{{Hatnote|This article is about the "Federations" mechanics. For the DLC, see [[Federations (DLC)]].}}
{{version|3.3}}
[[File:Federation_fleet.png|thumb|320px|A Federation fleet from every species class.]]
Federations are groups of empires that band together for mutual benefit. A federation is a more in-depth version of a Defense Pact with its own set of laws, rules and perks. Diplomatic relations inside of a federation become more favorable: members do not generate border friction amongst themselves, build trust with each other to a cap of {{green|+100}} and share 10% of their victory score with each other. Players can set a name for their federation at creation or leave it random; the name can be changed at any time. In the default map view, all federation members share the same color.

A federation can only be created by one of three ways. An empire that adopts the [[File:Tradition_diplomacy_the_federation.png|link=Traditions#Diplomacy|21px]] Federation [[tradition]] from the Diplomacy tree may create a Federation with another empire, an empire that has an origin that gives them a federation, or during the late game "War in Heaven," the strongest empire in the galaxy will get an event to create a League of Non Aligned powers, even if that strongest empire doesn't have the [[File:Tradition_diplomacy_the_federation.png|link=Traditions#Diplomacy|21px]] Federation [[tradition]]. Empires with the {{iconify|Barbaric Despoilers}} civic can create only a Martial Alliance or Hegemony federation. An invited empire must have a positive acceptance score with an existing federation member for said member to vote for their addition. Hovering over the diplomatic choice will show which empires agree and disagree.

Members of a federation have their {{iconify|Energy}} Output reduced by {{red|-15%}}. This tax doesn't apply to {{iconify|Energy}} generated from trade.

When a member leaves or is kicked from a federation it gains a [[File:diplomacy truce.png|24px]] Truce with the federation.

Leaving a federation will grant a temporary {{red|-200}} {{iconify|Opinion}} with all federation members.

== Federation types ==
The federation type determines what perks the federation will provide at each level. The federation type can be changed as the game progresses by clicking on the federation type icon. Changing the federation type, however, will reset the federation level to 1.

The Galactic Union federation type is available by default but all other federation types require the {{iconify|Federations}} DLC. The Trade League federation type additionally requires the {{iconify|MegaCorp}} DLC in order to meet the requirements.

=== Federation projects ===
Once 60 years pass, if a federation reached at least level 2 and is at peace its president may be offered the choice to start a joint project with the other federation members. The joint project lasts 10 years and requires each member to individually complete a special project. If not even a single member completes it the joint project will fail and the federation will gain {{red|−50}} {{iconify|Cohesion}}.
* {{iconify|Galactic Union}} and {{iconify|Research Cooperative}} federations have the objective of studying a space aurora. Each member will be given a special project above its capital starbase that requires a science ship with a level 2 or higher scientist and requires 200 {{iconify|Physics}} Research. Completing the special projects brings a choice but its effects are purely visual. The project is complete after 3 years or when every member finishes the special project.
** If all members participated the federation will gain {{green|+30}} {{iconify|Cohesion}} and each member will gain {{green|+10%}} {{iconify|Physics}} and {{green|+5%}} {{iconify|Society}} Research Research for 10 years
** If not all members participated each member that participated will gain {{green|+10%}} {{iconify|Physics}} Research for 6 years
* {{iconify|Hegemony}} federations have the objective of building a monument. Members that agree gain a temporary {{green|+30}} {{iconify|Opinion}} with the president while those that refuse gain {{red|−50}} {{iconify|Opinion}} with the president. If more than half of the members disagree the federation will lose 100 {{iconify|Cohesion}} and the president will lose 50 {{iconify|influence}}. If at least half of the members agree all members that agreed will be issued a special project above the president's capital which requires a construction ship and takes a year to complete, while the president will be issued a special project to give members {{green|+35%}} attraction towards the president's ethics which requires a science ship and takes 6 months to complete. Any member that finishes the special project will gain a temporary {{green|+50}} {{iconify|Opinion}} with the president. Once all member special projects are completed the project is completed.
** If all members participated the federation will gain {{green|+100}} {{iconify|Cohesion}} and the president will gain the [[File:D monument in space.png|24px]] Federation Monument planetary feature on the capital
** If not all members participated the federation will gain {{green|+25}} {{iconify|Cohesion}}
* {{iconify|Martial Alliance}} federations have as their objective a federation-wide fleet exercise. Members that agree gain a temporary {{green|+50}} {{iconify|Opinion}} with the president while those that refuse gain {{red|−50}} {{iconify|Opinion}} with the president. If more than half of the members disagree the federation will lose 100 {{iconify|Cohesion}} and the president will lose 50 {{iconify|influence}}. If at least half of the members agree the president and all members that agreed will be given a location in the Situation Log which they must reach with a fleet of at least 15 ships. Once each member reaches the location a hostile fleet of 5-9 ships will appear and must be defeated in 30 days. Once each fleet is defeated the project is completed.
** If all members participated the federation will gain {{green|+100}} {{iconify|Cohesion}} and each member will gain {{green|+15%}} {{iconify|Fire Rate}} for 25 years
** If not all members participated the federation will gain {{green|+50}} {{iconify|Cohesion}} and each member that participated will gain {{green|+15%}} {{iconify|Fire Rate}} for 25 years
* {{iconify|Trade League}} federations have the objective of creating a shipping standard. Within two years each member must generate in a star system at least 50 {{iconify|Trade Value}}. Members that fail will gain {{red|−10%}} {{iconify|Trade Value}} until the project is complete. Members that succeed will gain {{green|+5%}} {{iconify|Consumer Goods}} and {{red|−10%}} {{iconify|Trade Value}}, or only {{red|−5%}} if the  system's Starbase has an [[File:Sb offworld trading company.png|24px]] Offworld Trading Company building, and will be issued a special project on the system's Starbase that requires a construction ship. Once each member completes its special project all modifiers are removed and the project is completed.
** If all members participated each member will gain {{green|+5%}} {{iconify|Consumer Goods}} and {{green|+12%}} {{iconify|Trade Value}}
** If not all members participated each member that participated will gain {{green|+2.5%}} {{iconify|Consumer Goods}} and {{green|+10%}} {{iconify|Trade Value}}

== Federation Cohesion ==
Cohesion {{icon|cohesion}} is a measure of how unified a federation is and ranges from {{green|+100}} to {{red|-100}}. It has the following effects:
* Each 10 points of Cohesion above '''0''' adds {{green|+1}} XP per month to a federation, up to {{green|+10}} at {{green|+100}} Cohesion {{icon|cohesion}}.
* Each 10 points of Cohesion below '''0''' adds {{red|-1}} XP per month to a federation, up to {{red|-10}} at {{red|-100}} Cohesion {{icon|cohesion}}.
* Each 4 points of Cohesion above '''0''' adds {{green|+1}} Acceptance for changing federation laws.
* Each 4 points of Cohesion below '''0''' adds {{red|-1}} Acceptance for changing federation laws.
* Cohesion below {{green|90}} reduces the Acceptance for increasing the Centralization Law by {{red|-50}}.

The following incur '''immediate''' Cohesion {{icon|cohesion}} changes:
* {{red|-100}} whenever a member joins or leaves the federation.
* {{red|-50}} whenever federation Type changes
* {{red|-10}} whenever federation Centralization Law changes
* {{red|-5}} whenever any other federation law changes
* {{red|-10}} whenever a failed vote occurs

The following incur '''monthly''' Cohesion {{icon|cohesion}} changes:
* {{green|+1}} for each envoy assigned to the federation
* {{red|-0.25}} for each member of the federation
* {{red|-0.15}} multiplied by the number of different ethics, minus 3 (''moderate and fanatic ethics of the same type will count as different ethics'')
* {{red|-0.5}} for each opposed ethics (''Two opposing fanatics, or any combination with only a single fanatic will only count for one set of opposed ethics. Normal and fanatic on one side, and fanatic or normal and fanatic on the other will count for two.'')

If a federation loses the experience required for a level and fails to raise it above the required limit within 90 days, the federation level will downgrade and remove all perks from the previously held level. Each level requires the following amount of experience:
{|class = "wikitable" style="text-align:center;"
! Level
| 2 || 3 || 4 || 5
|-
! XP 
| 1200 || 3600 || 8400 || 18000
|-
! XP from previous level
| 1200 || 2400 || 4800 || 9600
|}
A federation's experience is capped at 18000, meaning that at level 5 any negative Cohesion will downgrade the federation level.

== Federation Fleet ==
Federations that have their Fleet Contribution law set to anything other than ''None'' feature a joint fleet in addition to the forces of the separate member empires, controlled by the current federation president. Federation fleets cost no maintenance and use the federation fleet capacity, to which every member contributes based on the Fleet Contribution law, up to 600. The fleets cannot exceed this cap. The Entente Coordination tradition doubles the naval capacity contribution of the members that adopt it while not reducing their own further. Federation fleets do not have a command limit.

The president designs the federation fleet ships via a special [[ship designer]] available in the federation menu and may use any [[technology]] available to any member empire. Regular ship designs cannot be used to build federation ships. The president's empire is responsible for commanding the federation fleets. Federation law determines whether any member of the federation or the president's empire alone can build ships for the federation fleet. Any AI federation member's research of a component-unlocking technology will auto-update the default federation designs, but not any player-created ones, adding theirs to the list instead. Since their designs are considered newer if you update your federation fleets at this time your fleet will become their design, which can be undesirable.

If a federation is disbanded, so is the federation fleet.

{{expansion|apc}}
The federation fleet has its own Titan limit, which does not affect the number of Titans its members can construct individually.

{{expansion|fed}}
The federation can include one Juggernaut regardless of whether any member empire has one of their own.

== Federation laws ==
Federation laws dictate how the federation operates and customize certain aspects of a federation. Any federation member can propose a law change. Hovering over any law will list the federation members that will oppose it. A failed vote will add {{red|−10}} {{iconify|Cohesion}}.

=== Federation Centralization ===
Federation Centralization determines what Federation laws are available and is limited by the current federation level. Raising centralization will incur increasingly higher cost to cohesion.

Each member is offered the chance to pay and place a bid or drop out. If multiple members placed a bid, then the offer is given again to those members. Bidding continues until all but one empire have dropped out. This remaining empire then becomes the new president and will also gain the option to invest the bids placed by all members, distribute them or appropriate them.
* Investing will give all federation members {{green|+10%}} {{iconify|Trade Value}} and {{green|+5%}} {{iconify|Energy Credits}} for a year
* Distributing will refund each member {{iconify|Energy Credits}} based on the sum made by all members
* Appropriating will grant the president {{iconify|Energy Credits}} based on the sum made by all members and give {{green|+5%}} {{iconify|Energy Credits}} and {{red|-100}} {{iconify|Opinion}} with all federation members for 50 years
