Nations on Earth serve as battlegrounds for the aliens' designs on Earth and are sites of both political and military conflict. Human factions, using councilors and armies, will compete to control nations in order to make use of their resources to fulfill their objectives.

Most nations in Terra Invicta correspond to a single real-world Earth country, although in several cases adjacent groups of small nations are aggregated into a single nation so they have more relevance to the scale of the game, and any inter-nation issues within these fake aggregates generally take place below the scale of the simulation. Factions function as something like covert investors in nations, and with enough focus they can take control over the nation's economy and foreign policy.

== National Stats ==
[[File:Nations screen.png|thumb|320px|Nation Stats view]]
The prosperity and stability of Earth's nations, already tenuous in many places, has been thrown into doubt in light of the alien arrival. Different events throughout the game may alter the qualities of a nation significantly. These circumstances are tracked and made visible to the player, who can take various actions to modify them.

===Population===

Nations are composed of regions that each have populations measured in millions. The total population of a nation is one of its most important stats, as population has significant effects on nearly all other stats, including but not limited to:
* Monthly IP production.
* Research output.
* The maximum amount of Mission Control Cap that can be built in each region.
* The maximum amount of armies that the nation can build.
* Spoils money output.
* Cohesion.
* Influence income from public support.
* Pollution output.

As a result, nations with larger populations tend to have far greater long-term potential. On the other hand, nations with larger populations are also slower to change their nation stats, because of the need to apply these changes to a larger number of people.

====Population Scaling for Nation Stat Changes====

The following nation stats are considered to apply to the entire population of the nation:
* Government
* Unrest
* Cohesion
* Inequality
* GDP per Capita
* Education
* Sustainability

As a result, most changes to these stats are slowed down in nations with larger populations. Specifically, the amount of change is divided by (the nation's population / 50 million) ^ 0.35.

Notably, the monthly IP production of a nation is multiplied by (the nation's population) ^ 0.35.
Consequently, two nations with different populations but otherwise identical stats would usually develop themselves at the same rate.

====Population Growth====

As of 0.4.84, the game calculates the annual population growth of a region as follows:

[[File:PopGrowth.png]]

WHAT THAT MEANS:
* Lower [[Nations#Education|education]] increases population growth by roughly 0.42% for each point of education below roughly 11, up to a maximum of roughly 4.08%.
* Higher [[Nations#Cohesion|cohesion]] decreases population growth by roughly 0.06% for each point of cohesion, up to a maximum of roughly 0.62%.
* Higher [[Nations#Per_Capita_GDP|GDP per capita]] increases population growth by roughly 0.098% for every 10k GDP per capita, up to a maximum of roughly 1.77%.
* Distance from the equator decreases population growth by 0.115739931206548% multiplied by the square root of the absolute latitude of the region.
* Every nation and region has a pop growth modifier, which is defined in plain text in TINationTemplate.json and TIRegionTemplate.json in the game files. These values are normally added directly to the annual population growth, but slowly fade away over time. After 25 years, they are completely removed.
* [[Aliens#Alien Xenoforming|Xenoflora]] decreases population growth by -1% per 200 levels of xenoflora growth. For reference, whenever xenoflora growth exceeds 100 levels, 50 levels are spent to spawn a megafauna.
* Nuclear fallout decreases population growth by 4% per layer of nuclear fallout. These can be removed through massive investments into the Environment priority.

The above effects are summed up and then capped between -10% and +10% annual population growth.

Then the effects of severe [[Climate Change]] are applied:
* For every degree of temperature anomaly above or below 8 degrees, population growth decreases by 1%.
* This effect is doubled for ecologically vulnerable regions.
* This effect is halved for ecologically protected regions.

At the start of every month, the population of every region is changed to match its projected annual population growth rate. But a small amount of randomization between -0.0412% and +0.0412% is also added to this monthly population change.

If the region population decreases, the nation's [[Nations#Education|education]] does too. If you lose more than 0.5 million (no, it does not scale with total population), you get the maximum reduction of -0.005. This can add up quickly in a large nation with many regions, each reducing the education by a maximum of -0.005 every month.

Note: This education decrease is only applied by the automatic monthly population change. Loss of population from other sources such as war or natural disasters has no effect on education.

=== Government ===
<blockquote>
A nation's Government score measures the amount of democracy in a country, which represents things like civil liberties, popular selection of leaders, press freedoms, and rule of law via an independent judiciary. This impacts many things, including national stability and cohesion, research production, corruption, economic growth and the effectiveness of the military in controlling unrest.
</blockquote>
~ Terra Invicta Codex, 0.4.85.

In a nation with 50 million population:
* Government increases by 0.001 per Education whenever the Government priority is completed.
* Government decreases by 0.0025 whenever the Oppression priority is completed.
* Government decreases by 0.0005 whenever the Spoils priority is completed.
In nations with smaller or larger populations, these changes are sped up or slowed down. See [[Nations#Population_Scaling_for_Nation_Stat_Changes]] for more detail.

The Government score impacts the Cohesion score. A low Government score increases the Cohesion resting point, a middle score lowers the Cohesion resting point, while a high score draws the Cohesion resting point towards a central value of 5, and simultaneously increases research production. A higher Government score also lowers the Spoils priority requirement to keep the national elites happy in order to avoid resetting of CPs by coup d'etat and boosts economic growth. A lower Government score increases the effectiveness of the Oppression priority and armies at reducing unrest.

Goverment score ranges from 0 to 10:
{| class="wikitable"
! Government !! Score range
|-
| Totalitarian || 0-2
|-
| Authoritarian || 2-4
|-
| Anocracy || 4-6
|-
| Flawed Democracy || 6-8
|-
| Full Democracy || 8-10
|}

=== Unrest ===
<blockquote>
The Unrest score represents violent resistance to the political, economic or cultural status quo in this nation. High unrest hampers the economy and may result in a coup or revolution, which will transfer or clear many or all of the nation's Control Points at once. Unrest is fed by low Cohesion and low quality of life (per-capita GDP). The Oppression priority, the Stabilize mission, and armies can reduce it, especially in non-democracies.
</blockquote>
~ Terra Invicta Codex, 0.4.85.

In a nation with 50 million population:
* Unrest decreases by (0.1 - Government / 100) whenever the Oppression priority is completed.
In nations with smaller or larger populations, these changes are sped up or slowed down. See [[Nations#Population_Scaling_for_Nation_Stat_Changes]] for more detail.

Unrest score ranges from 0 to 10. Every 0.1 point of Unrest above 2 will decrease Investment Points by 1%, capping at 80% at 10 unrest.
{| class="wikitable"

|}

==== Base Unrest ====

Unrest changes relatively quickly (0.25 per month, and even +1 per month if cohesion=0) if it is not at its resting point. This resting point is calculated as:
* 10.5
* -1 per 10k GDP per capita
* -1 per cohesion
* -0.1 per friendly army in the nation, multiplied by the army health %, multiplied by (10 - Government). Note: This is turned off if the nation cannot afford to pay its army upkeep.

For the Alien Administration, the base unrest is then further reduced by <code>the average of the the nation's regions' xenoforming level (from 0 to 100) / 20</code>.

It's generally better to reduce unrest resting point before reducing its value with councilors and the oppression priority, otherwise it will grow back naturally and quickly.

==== Coups and revolutions ====

Naturally occurring coups and revolutions can happen at high levels of unrest; the Alien Administration cannot experience a coup but it can experience a revolution. The chances of coups and revolutions are checked every four days, with each nation assigned to one of the four days in the cycle. Revolutions will always occur if <code>unrest > 9.9</code> when checked. A naturally occurring coup will never happen if <code>democracy >= 8</code> and <code>unrest < 8</code>; otherwise the <code>daily chance of coup * 4</code> is checked.

The daily chance of coup is <code>((unrest * 2 - cohesion - democracy) / 10 + elite unhappiness) / 6000</code>. The elites' unhappiness is zero if the spoils priority weight percentage matches or exceeds the nation's [[#Corruption|corruption]] or if one faction owns all the nation's control points and that faction's <code>popularity >= 65%</code>; otherwise it is <code>corruption - spoils percent</code> as value from 0.0 to 1.0.

So natural coups can be countered by lowering unrest and increasing cohesion, democracy and spoils (up to the corruption level). The spoils priority may often be ignored if the level of unrest in a country is sufficiently low and the democracy/cohesion sufficiently high, even if the indicator appears red (but note that elite happiness or unhappiness will still be a modifying factor in the chance of targeted coups).

=== GDP ===
<blockquote>
A nation's GDP, or Gross Domestic Product, is a measure of its annual economic output in U.S. dollars adjusted by purchasing power parity. The nation's GDP determines how many Control Points a nation has, how many Investment Points it produces, and how difficult certain missions there are.
</blockquote>
~ Terra Invicta Codex, 0.4.85.

The number of Control Points that a nation has is its (GDP in billions)^0.25/2, rounded to the nearest integer between 1 and 6.

{| class="wikitable" style="text-align: center;"
! GDP (Bn) !! Control Points
|-
| 0-81 || 1
|-
| 81-625 || 2
|-
| 625-2401 || 3
|-
| 2401-6561 || 4
|-
| 6561-14641 || 5
|-
| 14641+ || 6
|}

Whenever a nation's GDP grows to the point where it would gain a new control point, the new control point is added to the left and assigned to the same faction that controls the executive control point.

Whenever a nation's GDP shrinks to the point where it would lose a control point, the leftmost control point is removed.

==== Monthly Investment Points ====
These represent the nation's economic surplus that can be distributed by factions with Control Points in the Priorities tab. The value is set by the nation's GDP and reduced by the number of armies it fields and by high levels of unrest.
* The base value is equal to <code>(GDP in billions)^0.35</code>.
* Unrest decreases Monthly Investment Points by 1% for every 0.1 point of Unrest above 2, capping at -80% at 10 unrest.
* Navies decrease Monthly Investment Points by 0.5 per navy.
* Armies stationed in their home regions decrease Monthly Investment Points by 0.5 per army.
* Armies stationed in another region decrease Monthly Investment Points by 1 per army.
The overall formula is (GDP in billions)^0.35 * (1 - max(unrest-2, 0)/10) - 0.5*(# navies) - 0.5*(# idle armies at home) - 1*(# other armies).

The value can be significantly increased during a turn by assigning a councilor to Advise the nation. The n-th advisor adds +(Advisor Admin / n)% to the Monthly Investment Points.

==== Per Capita GDP ====

<blockquote>
A nation's per-capita GDP is its '''Gross Domestic Product''' divided by its population. It represents the economic conditions for the average citizen of this nation. Nations with low per-capita GDP will face higher unrest while the people's needs are not being met. Putting investment points into the Economy priority can increase GDP. Conflict, population loss, and climate change are among the things that can cause it to decrease.
</blockquote>
~ Terra Invicta Codex, 0.4.85.

In a nation with 50 million population, the Economy priority increases the GDP per capita by:
* 3 (Base value), slightly increased by certain global Techs.
* +1.5 per Resource Region.
* +1.5 per Core Economic Region.
* +0.5 per Government.
* +1 per Education.
In nations with smaller or larger populations, these changes are sped up or slowed down. See [[Nations#Population_Scaling_for_Nation_Stat_Changes]] for more detail.

This means that for maximum GDP growth, you want more democracy, more education, as well as as many economic and resource regions as possible.

It must be noted that a significant economic growth in a nation may also carry negative consequences to the planet's climate stability. Climate change has a negative effect on GDP that is increased by Inequality.

====GDP Per Region====

When distributing GDP to regions within a country, the game distributes them based on economic modifiers. It pretends regions with colonies have 50% the people who actually live there, and that resource and core economic regions have 125%, then distributes GDP evenly based on that modified population. This effectively means that regional GDP per capita is higher in core economic and resource states than in "regular" regions, and are lower in colonies.

This has a great effect on population growth as described in the first section, as the GDP per capita calculation in that section is per region. It also affects the amount of Mission Control cap that can be built in each region.

=== Education ===

<blockquote>
A nation's Education value is scored based on the average years of schooling a citizen in this nation receives as well as the quality of education there. Nations with higher education scores produce more research and are more resistant to extreme propaganda but gain less cohesion from the Unity priority.
</blockquote>
~ Terra Invicta Codex, 0.4.85.

In a nation with 50 million population:
* Education increases by 0.005 whenever the Knowledge priority is completed.
** Multiplied by 8.5 / Education if Education < 8.5.
** Multiplied by 12 / Education if Education > 12.
* Education decreases by 0.001 whenever the Unity priority is completed.
In nations with smaller or larger populations, these changes are sped up or slowed down. See [[Nations#Population_Scaling_for_Nation_Stat_Changes]] for more detail.

{| class="wikitable"
! [[File:ICO education.png|25px]] Education !! Score range
|-
| Limited || 0-5
|-
| Developing || 5-8
|-
| Advanced || 8+
|}

Education is one of the largest factors influencing national research output aside from population.

==== Research ====

As of 0.4.84, a nation's research output is calculated as:
[[File:ResearchMonth.png]]

In other words:

A) Base of 12 + Education Score. Capped at Population / 2000.

B) Population in millions.

C) If the GDP per capita is $30000 or lower, use the number (GDPPC/15000)^0.6.

If the GDP per capita is higher than $30000, use 1.5157166 + 0.90942997 * (ln(GDPPC/15000) - 0.6931472) instead.

note: 1.5157166 is approximate value of 2^0.6, 0.90942997 is approximation of 0.6*2^0.6, and 0.6931472 is about ln2.

D) Scales by education squared, then linearly at 12: Education * Max(Education, 12)

E) Scales by the sixth root of Democracy, with a floor of 1 at 1 Government: Max(Government0.16666667, 1) (maximum of ~1.4678).

F) 75% efficient at 10 and 0 Cohesion, scales linearly to 125% at 5 Cohesion.

G) 100% efficient at 0 unrest and 0% efficient at 10 unrest, scales with unrest squared: 1-(unrest2)/100

H) n% per science advisor with diminishing return: 1% per science of first advisor + 0.5% per science of second advisor + 0.333333% from 3rd etc, always sorted by advisor bonus, descending (best advisor will count towards the first bonus).

These elements are combined as following: (A + B × C × D × E x 0.0075) × F × G × H

=== Mission Control ===

<blockquote>
Completing the Mission Control priority grants one Mission Control to the nation. New facilities will tend to go in regions that already have Mission Control facilities. A region's Mission Control maximum capacity is a function of the region's GDP and education.
</blockquote>
~ Terra Invicta Codex, 0.4.85.

This is Mission Control that the nation is providing each month to be distributed to owners of its control points.

Whenever the Mission Control priority is completed, a random region in the nation is selected to increase its Mission Control by 1. This random selection is slightly weighted to favor capital and core economic regions over colony regions. It cannot select regions that are currently occupied by war enemies. It also cannot select any regions that have reached (or exceeded) their Maximum Mission Control.

The Maximum Mission Control of a region is calculated as 1 + [[#GDP_Per_Region|Region GDP]] in billions / Max(200, 300 - 6 * [[Nations#Education|Education]]), rounded down to the nearest integer.

In practice, this formula is dominated by the region Population and nation GDPPC factors, so players who wish to rapidly increase their nation's Maximum Mission Control should focus on the Economy priority over the Knowledge priority.

=== Boost ===

<blockquote>
The Boost priority covers the construction of launch facilities for rockets and other surface-to-orbit craft, increasing the nation's total boost. The amount of boost created increases with proximity to the equator, and new facilities will tend to go in regions that are closer to the equator or already have launch facilities.
</blockquote>
~ Terra Invicta Codex, 0.4.85.

This is Boost that the nation is providing each month to be distributed to owners of its control points.

Whenever the Boost priority is completed, a random region in the nation is selected to increase its Boost production. This random selection is heavily weighted to favor the regions that already produce the most Boost, with a slight preference for regions that would gain more Boost production when selected. It also heavily prefers regions that are not currently occupied by war enemies.

The amount of Boost production a region gains depends on the latitude of its Launch Facility. Specifically, the region's annual Boost production increases by 0.4 - (Launch Facility Latitude / 250).

So the worst regions are Iceland and Arkhangelsk, whose Launch Facility Latitudes of 65 mean that each only gains 0.14 annual Boost production when selected. Whereas the best regions are the 26 regions with Launch Facilities that are practically on the Equator: each gains 0.4 annual Boost production when selected.

'''Note''': Nations that are part of federations will share their boost with all other federation members. Larger nations will receive a much larger share of the Federation's total boost, with each nation's share being proportional to (the number of its control points) ^ 3.

=== Funding ===

<blockquote>
The Funding priority directs national resources into legitimate government and private efforts to support space programs and other goals for the owners of its control points. While not as profitable as the Spoils priority, it does no harm to the nation.
</blockquote>
~ Terra Invicta Codex, 0.4.85.

This is money that the nation is providing each month to be distributed to owners of its control points.

Whenever the Funding priority is completed, the nation's annual funding grows by 10 + (the nation's GDP in billions)^0.25 / 2, rounded to the nearest integer.

Notably, this is very similar to the formula used to determine how many control points a nation has. Thus in practice, the annual funding of a nation grows by 10 + the number of control points whenever the Funding priority is completed.

The annual funding of a nation is capped at the nation's GDP in billions multiplied by 5.

'''Note''': Nations that are part of federations will share their funding with all other federation members. Larger nations will receive a much larger share of the Federation's total funding, with each nation's share being proportional to (the number of its control points) ^ 3.

=== Miltech ===
A nation's Military Technology value represents the capability of the nation's armed forces.

Miltech is increased by 0.00125 whenever the Miltary priority is completed. This is further increased for nations that are falling behind on Miltech. Specifically, the effect is multiplied by (best Human Nation's Miltech / this nation's Miltech).

Unification between two nations balances the Miltech score between the two nations. Miltech applies to both army strength, which changes together with national Miltech level, and regional defence power.

Miltech score ranges from 2 to infinity. The Miltech age also determines the visual appearance of armies.
{| class="wikitable" style="text-align: center;"
! Score range
| 2-3 || 3-4 || 4-5 || 5-6 || 6-7 || 7-infinity
|-

| '''Invasion Age''' [[File:Army Tech6.png|110px]]
| '''Fusion Age''' [[File:Army Tech7.png|110px]]
|}

Initially the Miltech score is capped at level 5, which can be increased by 0.5 with each of the following global research technologies:
* [[File:Tech info icon.png|24px]] Cybernetics
* [[File:Tech info icon.png|24px]] Applied Artificial Intelligence
* [[File:Tech material icon.png|24px]] Next-Generation Aerospace

* [[File:Tech military icon.png|24px]] Coilguns
* [[File:Tech military icon.png|24px]] Trans-Interface Warfare
* [[File:Tech military icon.png|24px]] Future Tech: Military Science

=== Armies ===

<blockquote>
Armies are powerful and expensive assets that belong to nations. Each army represents multiple divisions of troops, air support, and a logistics train sufficient for the unit to take and hold territory outside their home nation's borders. Naval armies are supported by a combat and transport fleet, and are able to cross oceans if the nation's naval score exceeds that of its enemies. Armies are bound to a particular control point in a nation; the owner of that control point commands the army's actions. Use of armies on foreign soil are subject the nation's relations; they may be stationed in allied nations and only enter the territory of hostile nations during war. Each nation may have one army per region it controls; if a region joins another nation, any armies based in that region will belong to the new nation.
</blockquote>
~ Nation UI Tooltip for Armies, Terra Invicta, 0.4.86.

An army needs two things: people and land.
* Each army needs its own unique home region that is:
** Not shared by any other army.
** Not a colony region.
** Not occupied by enemy forces.
* Each army needs 25 million population in the nation.
** Except the first army of each nation gets a discount: it only needs 5 million population.

Some nations do not begin with any military, and must first complete the Found Military priority before they can build any armies.

=== Navies ===
A nation's naval score is calculated by the number of navies it has attached to its armies multiplied by the nation's military technology score.

There are three possible navy states:
* '''No Navies:''' No army has any navy attached.
* '''Freedom of the Seas:''' At least one army has a navy attached and there are no enemies with a higher naval score.
* '''Blockaded:''' At least one army has a navy attached and there are enemies with a higher naval score.

A nation can only build navies if one of the following is true:
* It has at least 4 control points.
* It has 3 control points and at least 40000 GDPPC.

=== Exofighters ===

Human nations can build exofighters after [[Orbital Fighters]] is researched.

Whenever the Build Exofighter priority is completed, a region in the nation is selected to increase its Exofighters by 1. The region is selected as follows:
* Exclude all regions that are at their Maximum Exofighters.
* If any remaining region has zero Exofighters, then pick the one with the highest Boost production.
* Pick the one with the highest Boost production divided by the number of Exofighters already in the region.

The Maximum Exofighters of a region is calculated as:
* 0 if the Monthly Boost Production is less than 1.
* Min(64, Monthly Boost Production / 4), rounded up to the nearest integer.

=== Strategic Nuclear Barrages ===
The number of strategic nuclear barrages that may be launched from this nation. Each barrage will devastate a single region and cause massive environmental damage globally. Nuclear strikes are directed by the faction in control of the executive control point.

Nuclear weapons can target any region belonging to current war enemies, or owned regions with enemy forces present. Note that advanced defenses will prevent any attack.

=== Space Defenses ===

<blockquote>
The Space Defenses priority constructs a surface-to-orbit weapons array in one region in the nation. More valuable and populous regions will be protected first. Space Defenses prevent alien landings and nuclear strikes on the region it is located in, and fire back at fleets conducting orbital bombardment against targets in the region. The cost varies with the size of the region being protected.
</blockquote>
~ Nation UI Tooltip for Space Defenses, Terra Invicta, 0.4.86.

Human Nations can build Space Defenses after [[Trans-Interface Warfare]] is researched.

Space Defenses are built in the following order:
# The Capital region.
# The Core Economic regions, from highest population to lowest.
# The Resource regions, from highest population to lowest.
# The Non-Colony regions, from highest population to lowest.
# The Colony Regions, from highest population to lowest.

The amount of IP needed to build Space Defenses in a region is calculated as 50 × Region Area / Median Region Area, but capped between 25 and 100.

=== Cohesion ===
A nation's Cohesion represents the level of unity or conflict among the people of the nation. This includes cultural, ideological, ethnic and religious similarities and differences. High values describe a unified society that brooks little deviation or dissent. Middle values represent a diverse society that has both internal conflict and a healthy, creative counterculture. Middle-low values represent a high degree of political polarization, and the lowest values mean the nation's people are fragmented or even tribal.

In a nation with 50 million population:
* Cohesion changes by 0.01 towards the central value of 5 whenever the Knowledge priority is completed.
* Cohesion increases by 0.1 whenever the Unity priority is completed.
** This is reduced by 0.005 per [[Nations#Education|Education]].
** This is reduced by 0.005 per [[Nations#Government|Government]].
** This cannot be reduced below 0.025.
* If [[Nations#Government|Government]] > 5, then Cohesion decreases by 0.025 per [[Nations#Government|Government]] over 5 whenever the Oppression priority is completed.
In nations with smaller or larger populations, these changes are sped up or slowed down. See [[Nations#Population_Scaling_for_Nation_Stat_Changes]] for more detail.

Cohesion moves 0.1 per month towards its resting point. In nations with high inequality, cohesion can decrease even faster, up to 0.25 per month towards its resting point. This is rapid enough that it is usually better to move the resting point rather than trying to fight the tide. The resting point can be increased by decreasing [[#Inequality|inequality]] with the Welfare priority.

Cohesion score ranges from 0 to 10:
{| class="wikitable"

| Fragmented || 0-1 || rowspan=4 | Unrest increases

|}

==== Current cohesion ====

If a nation's current cohesion is different from its rest point, it will shift by +/- 0.1 per month until it reaches the rest point. In nations with high inequality, the decrease is sped up, up to a maximum of -0.25 per month. It can also be actively changed by events, or by player actions. It is:

'''raised by:'''
* Investment in the Unity priority
* Declaring war on an ''established'' rival (provided: the nation was at peace before declaring the war, its current cohesion is 2–8, and one of nations involved is not democratic)
* Getting declared war upon, while having at least 2 cohesion.

'''centered by:'''
* Investment in the Knowledge priority

'''lowered by:'''
* Declaring war on a ''new'' rival
* Destruction of armies
* Investment in the Oppression priority when Government > 5.

==== Resting Cohesion ====

Resting cohesion depends on the following factors:

=== Public Opinion ===

<blockquote>
The people of Earth all hold a particular viewpoint about the alien arrival. But people are malleable, and events and propaganda can sway them to a different point of view.

These viewpoints track with the ideologies of each faction, along with an "undecided" viewpoint in the middle of all of them. Ideologies have a position relative to each other; when events have a chance to change someone's opinion, they will typically move to something nearby -- a Resistance supporter could see their views radicalize to those of Humanity First, or soften to being simply undecided, for example.

Public support for your faction is a primary source of the influence resource. You will also receive bonuses on missions in nations where a large portion of the public is on your side.

A potential mover of public opinion are atrocities committed by a faction. Atrocities are actions that cause mass death or suffering, and responsible factions suffer the loss of supporters as a result. Atrocities are cumulative; as a faction commits more, the public opinion penalty increases dramatically.
</blockquote>
~ Terra Invicta Codex, 0.4.85.

Public support for a faction provides many benefits, including but not limited to:
; Influence Income
: For every one million supporters a faction possesses, their annual Influence income is increased by 0.5.
: This bonus applies even if the faction does not possess any of the nation's control points.
: With over 8 billion people on Earth, a faction with high public support around the globe could earn more than 200 Influence every month, just from their public support.
; Councilor Mission Support
: Most councilor missions that attempt to gain or maintain control of the nation have mission modifiers based on the nation's public opinion. Public support for a faction makes such missions significantly easier for them, and significantly harder against them.
: This is especially true in highly democratic nations.
: Specifically, the mission modifier has X points, where X = (10 + Government) * public support fraction for the faction.
; Preventing Organic Coups
: In very rare cases, high [[Nations#Corruption|Corruption]] in a nation can lead its elites to organically launch a coup even without outside intervention, if they are not sufficiently appeased by investments into the Spoils priority.
: But high public support (>65%) for the faction that owns the nation automatically prevents such organic coups from occurring.
; Post-Revolution Changes
: Whenever a revolution occurs in a nation, public support for the old control point owners is compared to public support for the new control point owners. If the new owners are significantly more popular with the public, the nation can experience large benefits: increased cohesion, reduced unrest, and reduced inequality.
; Cohesion Rest Value
: Public opinion affects the Cohesion Rest Value of a nation in two ways.
: First, factions that own a nation will find the nation to be significantly less cohesive when the public does not support them. This is represented as an X point penalty to the nation's Cohesion Rest Value, where X is twice the ideological distance between the average ideology of the factions that own the nation's control points and the population-weighted average ideology of the public.
: Note: ideological distance is calculated using good old pythagoras.
: Second, a public with wildly differing views is naturally far less cohesive than a public that bands together to support one ideology. This is represented as an X point penalty to the nation's Cohesion Rest Value, where X is calculated as follows:
: 1. Set X to be the public opinion's standard deviation.
: 2. Divide X by the worst possible standard deviation (this is when the two most different ideologies are each supported by exactly half the public).
: 3. Subtract 0.5 from X.
: 4. Multiply X by 6.
: Note: X can actually be negative, meaning that the Cohesion Rest Value can actually be increased by a highly unified public opinion.

==== Changing Public Opinion ====

A nation's public opinion can be changed by applying Propaganda to it. Each piece of propaganda is defined by two things: the '''faction ideology''' it is aimed at, and the '''strength''' of the propaganda. For example, a typical public campaign mission applies Propaganda for the councilor's faction, with a strength of roughly 10.

===== How Propaganda Works =====

[[File:Terra Invicta Ideology Map.JPG|thumb|320px|Faction Ideology Chart]]

Whenever Propaganda of strength X for a faction F is applied on a nation, the population of the nation is split into roughly (population / 100) ^ 0.5 groups, where each group fully supports one ideology. Then for each group:
* Nothing happens if any of the following are true:
** X >= 0 and the group already supports faction F. Because this is just preaching to the choir.
** X < 0 and the group does not support faction F.
** An X% chance roll fails, indicating that the propaganda failed to convince the group.
* If X >= 0, then:
** There is a 10/X chance that the group's ideology moves towards F's ideology by 1 unit, then moves to the closest matching ideology.
** Otherwise the group's ideology moves towards F's ideology by 2 units, then moves to the closest matching ideology.
* If X < 0, then:
** There is a 10/X chance that the group's ideology moves by 1 unit in a completely random direction away from F (but in 3 dimensions), then moves to the closest matching ideology.
** Otherwise the group's ideology is moved to a completely random coordinate within a square of length 2 that is centered on the group's original ideology, and then the group moves to the closest matching ideology.

===== Sources of Propaganda =====

These include but are not limited to:
; A Successful Councilor Public Campaign
: Applies propaganda for the councilor's faction with strength X, where X is calculated as:
: 1. Set X = 10.
: 2. If the mission is a critical success, multiply X by 2.
: 3. Add the Earth Interface Hab Module bonus from Broadcast Outlets, Communications Hubs, and Media Centers to X (capped at +9).
: 4. Multiply X by 115% if [[Appeal to Hope Messaging]] has been researched. (Only available to [[The Resistance]], [[Project Exodus]], and [[The Academy]].)
: 5. Multiply X by 125% if [[Appeal to Fear Messaging]] has been researched. (Only available to [[Humanity First]], [[The Initiative]], [[The Protectorate]], and [[The Servants]].)
{{SpoilerBox}}
: 6. Multiply X by 125% if [[Enslave the Masters]] has been researched. (Only available to [[The Initiative]].)
{{SpoilerBoxEnd}}
: 7. Add a random value between -3.5 and +3.5 to X.
; A Unity Priority Completion
: Applies propaganda for each faction that owns any of the nation's control points.
: Propaganda strength is 5 multiplied by the number of control points owned by the faction, but the Religion control point counts as 4 control points.
: Propaganda strength is also affected by [[Nations#Population_Scaling_for_Nation_Stat_Changes|Population Scaling]].
; A Spoils Priority Completion
: Applies propaganda for each faction that owns any of the nation's control points.
: Propaganda strength is ([[Nations#Education|Education]] + [[Nations#Government|Government]]) multiplied by -0.125 multiplied by the fraction of the nation's control points owned by the faction.
; An Army Destroyed
: Applies propaganda for the faction that controlled the army on the home nation of the army.
: Propaganda strength is [[Nations#Government|Government]] multiplied by -1.
; A Martyr Councilor Killed
: Applies propaganda for the councilor's faction on every nation.
: Propaganda strength is 35.
; An [[Factions#Atrocity|Atrocity]] Committed
: Applies propaganda with strength X for the faction responsible on every nation, where X is calculated as:
: 1. Set X to the total number of atrocities committed by the faction, including the newest atrocity.
: 2. Multiply X by -0.333.
: 3. Divide X by 2 if [[Total War Framing]] has been researched. (Only Available to [[Humanity First]], [[The Initiative]], and [[The Servants]].)
; [[Publicize Alien Threat]] Researched
: Applies propaganda with strength 10 for the faction responsible on every nation.
: Only Available to [[Humanity First]], [[The Resistance]], and [[Project Exodus]].

=== Sustainability ===
<blockquote>
A nation's Sustainability value represents its ability to prevent emissions of greenhouse gases into the atmosphere from the economic activity within its borders. It represents the offset from expected emissions of Carbon Dioxide, Methane, and Nitrous Oxide based on the nation's GDP, population, and presence of oil resource regions.
</blockquote>
~ Terra Invicta Codex, 0.4.85.

In Terra Invicta, every nation has a Pollution Multiplier that caps at 10. This Pollution Multiplier multiplies:
* The amount of [[Climate_Change#Greenhouse_Gas_(GHG)_Sources|Greenhouse Gases]] that the nation passively produces each month.
* The amount of [[Climate_Change#Greenhouse_Gas_(GHG)_Sources|Greenhouse Gases]] that the nation produces whenever it completes the Spoils priority.

The Pollution Multiplier initially cannot go below a minimum value of 0.3325. But researching all of the following technologies would reduce this minimum value down to the limit of 0:
* [[Arrival International Development]] reduces the minimum by 0.05.
* [[Designer Lifeforms]] reduces the minimum by 0.05.
* [[Integrated Earth-Space Economy]] reduces the minimum by 0.05.
* [[Clean Energy]] reduces the minimum by 0.1.
* [[Climate Change Mitigation]] reduces the minimum by 0.1.

In a nation with 50 million population:
* The Pollution Multiplier increases by 0.0005 whenever the Spoils priority is completed.
** This is further increased by 0.0005 per Resource Region.
* The Pollution Multiplier decreases by -0.005 whenever the Environment priority is completed.
** Multiplied by the Pollution Multiplier / 2 if the Pollution Multiplier > 2.
** Multiplied by Max(0.25, the Pollution Multiplier / 0.5) if the Pollution Multiplier < 0.5.
** Divided by the number of layers of nuclear fallout within the nation, if the nation has any layers of nuclear fallout.

In nations with smaller or larger populations, these changes are sped up or slowed down. See [[Nations#Population_Scaling_for_Nation_Stat_Changes]] for more detail.

'''Note''': Region damage, such as from natural disasters and war, can rapidly increase a nation's Pollution Multiplier.

A nation's Sustainability value is calculated as:
* 10 if the Pollution Multiplier = 0.
* 9.99+ if (1 / the Pollution Multiplier) > 9.99.
* 9.9+ if (1 / the Pollution Multiplier) > 9.9.
* 1 / the Pollution Multiplier otherwise.

Once a nation's Sustainability value reaches 10 (its Pollution Multiplier reaches 0), the Environment priority will begin to remove [[Climate_Change#Greenhouse_Gas_(GHG)_Sources|Greenhouse Gases]] from the atmosphere.

At this point, there is a significant change: the [[Nations#Population_Scaling_for_Nation_Stat_Changes | population scaling]] effect gets inverted. A larger population is now a boon: the amount of [[Climate_Change#Greenhouse_Gas_(GHG)_Sources|Greenhouse Gases]] removed whenever the Environment priority is completed is now multiplied by (the nation's population / 50 million) ^ 0.35.

Hence, a player who wishes to fix the [[Climate_Change|Climate]] should aim to make the most populated nations reach Sustainability 10, and then heavily invest into the Environment priority.

=== Inequality ===
<blockquote>
A nation's Inequality score is a measure of how wealth and income is distributed in the nation. High values mean the nation doesn't have much of a middle class. Inequality grows by a little as a product of normal economic activity (the Economy Priority) or by a lot because of corruption (the Spoils Priority). Resource regions in a nation can contribute to inequality. High inequality reduces Cohesion as the nation divides into haves and have-nots. It is countered by use of the Welfare priority.
</blockquote>
~ Terra Invicta Codex, 0.4.85.

In a nation with 50 million population:
* Inequality increases by 0.00015 whenever the Economy priority is completed.
** This is further increased by 0.0001 per Resource Region.
* Inequality increases by 0.0025 whenever the Spoils priority is completed.
** This is further increased by 0.001 per Resource Region.
* Inequality decreases by 0.005 whenever the Welfare priority is completed.
In nations with smaller or larger populations, these changes are sped up or slowed down. See [[Nations#Population_Scaling_for_Nation_Stat_Changes]] for more detail.

Inequality score ranges from 1 to 9:
{| class="wikitable"
! [[File:ICO inequality.png|25px]] Inequality !! Score range
|-
| Very Low || 1-2
|-
| Low || 2-3
|-
| Moderate || 3-4
|-
| High || 4-5
|-
| Very High || 5-6
|-
| Extreme || 6-9
|}

'''Note''': Whenever a nation's Inequality would grow beyond 9, the excess amount is instead subtracted from Cohesion and added to Unrest.

===Corruption===
Corruption is a hidden value which determines what percentage of the economy the elites want diverted to spoils. If this is not done then coups become easier to perform against the nation, to the point where they might even naturally occur without any faction's involvement. Conversely, spoiling more than the elites want will cause them to protect your nation from councilor coup attempts.

As of 0.4.84, corruption is calculated as follows:

[[File:Corruption.png]]

In other words, for human nations, corruption is calculated as follows:
* 50% base value.
* Decreased by 2.65515% for every point of Government score.
* Decreased by 0.57342% for every point of Cohesion.
* Decreased by 2.748746667% for every 10k GDP per capita.
* Multiplied by 0.8 if the [[A Common Concern]] project has been researched.
** Note: Only available to [[The Resistance]], [[The Academy]], [[Project Exodus]], and [[The Servants]].
* Capped from below at 5%.

The Alien Administration always has 0% corruption.

== Priorities ==
The settings in the Priorities tab control the distribution of Investment Points, which represent surplus economic capital generated by the nation.

The owner of each control point may direct a share of investment Points into any number of priorities, either by selecting a present in the dropdown menu or setting them directly by clicking a spot in the grid.

Investment points are distributed by setting weights (0,1,2 or 3) for each priority, and the amount of investment going to a particular priority depends on the total number of weights set for a particular control point.

Investment Points gradually fill buckets for each priority; once filled, the nation receives the effects of that priority, and in most cases it may be filled again.

Some priorities will be highlighted red if they are considered critical to the nation.

=== Direct Investment ===
Direct Investment allows a faction to purchase Investment Points in a certain priority with Money, Influence, and/or Ops. The cost increases with the nation's GDP. If the nation was recently conquered in war, most Influence costs are halved (with the notable exception of Funding). The number of Investment Points that may be purchased each calendar year in any nation is capped at 12 × (Population in Millions × 48.75) ^ 0.175 × (GDP in Billions)^0.175, rounded to the nearest integer.

=== Elites ===
Each nation requires a certain percentage of Investment Points to be put into the Spoils priority. Failing to provide enough Investment Points into Spoils, shown by the priority becoming red, increases the chance of a coup d'etat. See [[Nations#Corruption]] for details on how this percentage is calculated.

== Control Points ==
Control Points represent key nodes of political and economic power in a nation. The number of control points is set by the fourth root of the nation's GDP: <code>max(round(((GDP in billions)^0.25)/2),6)</code>.

The faction that owns a control point has loyal followers in positions of authority. Control points grant their faction a portion of the nation's critical resources, control over the nation's armies, and the ability to direct economic priorities.

Certain powerful policies, such as joining and leaving federations and merging nations, require Consolidated control of the executive, which means the executive faction either gained control of the nation through war or revolution, or must have held continuous control of the executive point for 180 days.

Once a faction has accumulated a sufficient amount of control in multiple nations, additional control points cost influence per month to maintain, and Crackdown and Purge missions against the faction's control points will receive a bonus. The cost increases with the more control points a faction owns, and the size of the economy of each nation the faction owns control in. Control points that have sustained a Crackdown do not cost any influence to maintain.

When a faction is over the control point capacity, agents from other factions get a bonus operation strength against the control points of this faction. The bonus strength is 0.333 per 1 point over the capacity (+1 strength per every 3 points over the capacity). Missions that get this bonus are: Crackdown, Purge, Enthrall Elites and Dominate Nation.

Every nation has between 1 and 6 control points, depending on their GDP. The "cost against cap" to hold the entire nation is equal to GDP ^ 0.6 / 2, divided up equally among the control points.

Each faction will receive a fraction of funding, research, boost, mission control and spoils money produced by the nation. That fraction is equal to a proportion of controlled CPs versus all CPs of a nation.

If there are armies controlled by the nation, getting control of CP may also grant you direct control of said armies. CPs with armies attached to them are shown with yellow star in a green hexagon symbol next to them. If there is more than one army attached to a control point then the number of attached armies is shown over the symbol.

To gain control over a neutral CP one must perform a successful Control Nation mission with one of their councillors. Under normal circumstances, in nations with over 1 CP, executive CP can only be controlled if you already have a point in a nation and it is the last CP to be taken. If every nation has all of their CPs controlled by factions, Control Nation mission becomes unavailable. In that case you would need to perform a successful purge mission on an enemy controlled CP.

To increase purge chances, it is recommended to conduct crackdown on these CPs first. Another alternative to Control Nation is Coup d'Etat. It can either be performed with your councillor or happen naturally. Successful Coup d'Etat missions will turn all the CP from that nation to your faction, while Coup d'Etat happening on its own will reset all of CPs in the country to neutral; this allows every faction to conduct Control Nation missions. Coup d'Etat is a lot more likely to be successfully performed or occur in nations with high unrest, so boosting chances often needs Increase Unrest missions beforehand.

One more alternative is to simply use war. When armies conquer a nation's capital region, all control points in the nation switch owners to whichever faction conquered them.

=== Control Point Types ===

Control points come in a variety of types. Their type depends on the national [[Nations#Government|Government]] and other conditions, and provides a related bonus for the faction controlling it.

== Policies ==
Policies are actions the executive faction of a nation can take to dramatically alter the course of the nation. A councillor can use the Set Policy mission to enact policies. Certain policies require the target nation to accept them, the success rate depending on how similar the two nations are. Such policies are always acceptted if the same faction has executive control of both nations. Possible policies are:
{| class="wikitable"
! width=1% | Policy !! width=55% | Effects !! Requirements
|-
| '''Declare War'''
| Go to war against the rival nation and all its allies with armies or nuclear weapons. Own allies can choose to join the war.
|
* Any army
* Target is a rival
* Not breakaway nation
|-
| '''Seek Peace'''
| End a war against the targeted nation and all its allies.
|
* War leader
* Target is at war with this nation
* Target nation accepts (can be skipped by controlling its executive control point)
|-
| '''Grant Independence'''
| Targeted nation or region becomes independent. Gain control of all its control points.
|
* Parent nation of a breakaway nation or another nation has claims on regions controll by this one
* Consolidated control of the executive control point
|-
| '''Cede Territory'''
| Targeted nation gains control of all claimed territories controlled. If there is a rivalry it is ended.
|
* Another nation has claims to at least one controlled region
* If there is only one claimed region it must not have the Capital Region classification
* Consolidated control of the executive control point
|-
| '''Disband Army'''
| Disband one of the nation's armies.
|
* Any army
|-
| '''Disband Warheads'''
| Remove up to 5 Strategic Nuclear Barrages from the nation. If the last one is removed also cancel all progress on the nuclear weapons priority.
|
* Any strategic nuclear barrage
* Consolidated control of the executive control point
|-
| '''Declare Independence'''
| Removes the breakaway nation state. Go to war against the parent nation. Own allies can choose to join the war.
|
* Breakaway nation
* Target is the parent nation
|-
| '''Leave Federation'''
| Leaves the targeted federation.
|
* Member of a federation
* Consolidated control of the executive control point
|-
| '''Federation'''
| Creates a Federation with the targeted nation, or join theirs if they're already in one.
|
* Allied with the targeted nation for some time
* Claims to one of the federation's regions or federation has a clain to one of the nation's regions
* Not a rival or at war with any of the federation's members
* Not breakaway nation
* Not already in a federation
* Consolidated control of the executive control point
* Target nation accepts (can be skipped by controlling its executive control point)
|-
| '''Unification'''
| Both nations unite into a single nation. For each priority category, half of the joining nation's progress is added to all of the receiving nation's progress. Education, Per Capita GDP and Inequality are averaged depending on population. Miltech is averaged based on the number of armies. If the joining nation has a space program, the absorbing nation gains it. If the absorbed country has a nuclear program and the joining nation does not, all nukes are lost. All breakaway nations of the joining nation become independent. May cause regions of the joining nation to secede if Cohesion is below 5. Government remains unchanged but if the joining nation has more Government score than the absorbing nation, Unrest increases by half of the difference.
|
* Claims to the target nation's capital region
* Member of the same federation or original nation for some time
* Consolidated control of the executive control point
* Consolidated control of the executive control point of the targeted nation
* Control of all control points in the targeted nation

A symbol of a hand casting a ballot, found in the top right corner of overview screen, prompts a tooltip in which the available national policies are listed. Here one can also find cooldown periods for countries, with whom diplomatic actions may become available after the timer expires.

=== Federations ===
Federations are groupings of closely aligned nations that are pledged to provide mutual defence and share space program funding and boost. They are led by the predetermined member with the most significant international ambitions.

At the game start date there are two federations:
* [[File:Flag European Union.png|50px]] '''European Union:''' France (leader), Czech Republic, Slovakia, Germany, Italy, Spain, Benelux, Alpine States, Poland, Portugal, Sweden, Finland, Ireland, Northern Balkan States, Baltic States, Hungary, Romania, Bulgaria, Greece, Denmark
* [[File:Flag Eurasian Union.png|50px]] '''Eurasian Union:''' Russia (leader), Kazakhstan, Belarus, Armenia, Kyrgyzstan

When a federation or unification is created it will have the name and flag of its initial nation. However certain nations will create federations or unifications with unique names and flags.

===Unification===
If the capital region of an absorbed country (Kazakhstan inside Russia, Tigray inside Ethiopia, etc) is not claimed by the absorbing nation (e.g. EU with extra claims absorbing Russia), there's a chance the country becomes a breakaway, like Taiwan is at game start. The chance is 75% if the absorbed nation has 0 cohesion, scaling to 0% if the absorbed nation has 5 cohesion. This chance applies per region that happens to be a capital, and creates a breakaway state that takes all claimed regions with it.

For instance, if the EU absorbed a Russia that had absorbed central asia, there are five regions they do not have claims on that happen to be capital regions; kyrgyzstan, tajikistan, uzbekistan, turkenistan, and nur-sultan. If Russia has a cohesion of 3, that means every one of these regions have a 30% chance of creating a breakaway. Kazakhstan would Almaty along for the ride. If the EU had a democracy score lower than 7, any armies stationed in breakaways would be destroyed. A democracy score higher than 7 means there is no breakaway state; the country just becomes independent.

=== Claims ===
Some nations have claims on regions that aren't theirs. These are the regions they may acquire through warfare or secession movements. Several social science projects can unlock new claims during the campaign.

Completing certain research projects will increase the number of claims. The following claims exist at the start:
* [[File:Flag France.png|30px]] France has a claim on every member of the [[File:Flag European Union.png|30px]] European Union and United Kingdom, Southern Balkan States, Ukraine, Moldova and Georgia and Sevastopol ([[File:Flag Russia.png|30px]] Russia)

[[File:Relations tab.png|thumb|320px|Relations view]]

== Foreign Relations ==
The Relations tab describes the relations between different nations.
* '''Allies''' are nations that will support this nation when attacked, and may hold a policy vote to join a war started by this nation. Allies may host one another's armies as well.
* '''Rivals''' are nations with which this nation may go to war.

Changes in relations between nations are accomplished by policy votes, which may be initiated by a councilor or by the nation itself. Actions that improve relations also trigger a cooldown between the nations for improving relations again.

There are a few restrictions on who can ally and become rivals. Two nonadjacent nations with only one or two control points may not form alliances or rivalries unless one also has a navy. Nations allied with breakaway nations cannot ally with the breakaway's parent nation, and vice versa.

Improving relations requires the consent of the targeted nation. This can be skipped by controlling the executive control points in both nations.

Hovering over the alliance option will also show the detailed requirements for federation and unification.

=== Breakaway Nations ===
Nations that secede from another nations become breakaway nations. Breakaway nations are always Rivals with their parent nations and cannot declare wars, join wars or join federations. Allies of breakaway nations are also always Rivals with the parent nation. This state can be ended by either the breakaway nation using the Declare Independence policy or the parent nation using the Grant Independence policy.

When the game starts there are four breakaway nations - Taiwan, Palestine, South Yemen, and Somaliland.
