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 +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 an empire that adopts the Tradition diplomacy the federation.png Federation tradition from the Diplomacy tree, whether that be through Unity or through an origin. Empires with the Civic barbaric despoilers.png 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 Energy Credits.png Energy Output reduced by -15%. This tax doesn't apply to Energy Credits.png Energy generated from trade.

When a member leaves or is kicked from a Federation it gains a Diplomacy truce.png Truce with the Federation.

Leaving a Federation will grant a temporary -200 Diplomacy opinion.png Opinion with all Federation members.

Federation types[edit]

The Federation type determines what perks will the Federation 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 requires the Federations DLC.

Federation projects[edit]

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 -50 Federation cohesion.png Cohesion.

  • Federation default.png Galactic Union and Federation research.png Research Cooperative Federations have as objective 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 Physics Research 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 +30 Federation cohesion.png Cohesion and each member will gain +10% Physics Research Physics and +5% Society Research Society Research Research for 10 years
    • If not all members participated each member that participated will gain +10% Physics Research Physics Research for 6 years
  • Hegemony Hegemony Federations have as objective building a monument. Members that agree gain a temporary +30 Diplomacy opinion.png Opinion with the president while those that refuse gain -50 Diplomacy opinion.png Opinion with the president. If more than half of the members disagree the Federation will lose 100 Federation cohesion.png Cohesion and the president will lose 50 Influence.png 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 +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 +50 Diplomacy opinion.png Opinion with the president. Once all member special projects are completed the project is completed.
    • If all members participated the Federation will gain +100 Federation cohesion.png Cohesion and the president will gain the D monument in space.png Federation Monument planetary feature on the capital
    • If not all members participated the Federation will gain +25 Federation cohesion.png Cohesion
  • Federation military.png Martial Alliance Federations have as objective a Federation-wide fleet exercise. Members that agree gain a temporary +50 Diplomacy opinion.png Opinion with the president while those that refuse gain -50 Diplomacy opinion.png Opinion with the president. If more than half of the members disagree the Federation will lose 100 Federation cohesion.png Cohesion and the president will lose 50 Influence.png 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 +100 Federation cohesion.png Cohesion and the each member will gain +15% Mod ship fire rate mult.png Fire Rate for 25 years
    • If not all members participated the Federation will gain +50 Federation cohesion.png Cohesion and the each member that participated will gain +15% Mod ship fire rate mult.png Fire Rate for 25 years
  • Federation trade.png Trade League Federations have as objective creating a shipping standard. Within two years each member must generate in a star system at least 50 Trade value.png Trade Value. Members that fail will gain -10% Trade value.png Trade Value until the project is complete. Members that succeed will gain +5% Consumer goods.png Consumer Goods and -10% Trade value.png Trade Value, or only -5% if the system's Starbase has an Sb offworld trading company.png 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 +5% Consumer goods.png Consumer Goods and +12% Trade value.png Trade Value
    • If not all members participated each member that participated will gain +2.5% Consumer goods.png Consumer Goods and +10% Trade value.png Trade Value

Federation Cohesion[edit]

Cohesion Federation cohesion.png is a measure of how unified a Federation is and ranges from +100 to -100. It has the following effects:

  • Each 10 points of Cohesion above 0 adds +1 XP per month to a Federation, up to +10 at +100 Cohesion Federation cohesion.png.
  • Each 10 points of Cohesion below 0 adds -1 XP per month to a Federation, up to -10 at -100 Cohesion Federation cohesion.png.
  • Each 4 points of Cohesion above 0 adds +1 Acceptance for changing Federation Laws.
  • Each 4 points of Cohesion below 0 adds -1 Acceptance for changing Federation Laws.
  • Cohesion below 90 reduces the Acceptance for increasing the Centralization Law by -50.

The following incur immediate Cohesion Federation cohesion.png changes:

  • -100 whenever a member joins or leaves the Federation.
  • -50 whenever Federation Type changes
  • -10 whenever Federation Centralization Law changes
  • -5 whenever any other Federation Law changes
  • -10 whenever a failed vote occurs

The following incur monthly Cohesion Federation cohesion.png changes:

  • +1 for each envoy assigned to the Federation
  • -0.25 for each member of the Federation
  • -0.15 multiplied by the number of different ethics, minus 3 (moderate and fanatic ethics of the same type will count as different ethics)
  • -0.5 for each opposed ethics (unclear as of yet what gives the exact number of opposed ethics)

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:

Level 2 3 4 5
XP 1200 3600 8400 18000

A Federation's experience is capped at 18000, meaning that at level 5 any negative Cohesion will downgrade the Federation level.

Federation Fleet[edit]

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.

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

The federation can include one Juggernaut regardless of whether any member empire has one of their own.

Federation laws[edit]

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 −10 Federation cohesion.png Cohesion.

Federation Centralization[edit]

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.

Type Federation cohesion.png Monthly cohesion Required level Description
Minimal 0 1 The Federation's influence over its members is kept at a minimum.
Low −1 2 The level of Federation influence over member states are kept very low.
Medium −2 3 The Federation has a good deal of influence over its members, while still allowing some independent governing.
High −3 4 The Federation's influence over its member states is almost absolute.
Very High −4 5 The Federation has sovereign control over how member states are being governed.

Fleet Contribution[edit]

The Fleet Contribution law determines how much Mod fleet size add.png naval capacity is transferred from federation members to the federation fleet. The availability of laws is heavily affected by the federation type.

Type Federation cohesion.png Monthly cohesion Mod fleet size add.png Transferred naval capacity Max Fleet Size Required centralization Desctiption
Federation default.png Galactic Union Hegemony Hegemony Federation military.png Martial Alliance Federation research.png Research Cooperative Federation trade.png Trade League

Medium −0.5 20% 400 Medium Low Low Very High Medium This federation has a moderate collaborative military effort.
High −0.75 30% 600 High High Medium No.png Very High This federation has a extensive collaborative military effort.

Federation Fleet Construction[edit]

The Federation Fleet Construction law determines who can build ships for the federation fleet.

Type Effects Required Centralization
Everyone All members can build ships for the federation fleet Minimal
Only Leader Only the federation president can build ships for the federation fleet Low

Succession Type[edit]

The Succession Type law determines how the next federation president is chosen once their term is up.

Type Federation cohesion.png Monthly cohesion Effects Required centralization DLC
Rotation -0.5 Leadership is rotated among each Federation member Minimal
Strongest −1 The empire with the highest succession power becomes the next president Minimal if Hegemony
High if Other
Random The next president is chosen randomly Minimal Federations
Challenge The empire that wins the challenge becomes the next president Low Federations

Succession Power[edit]

If the Succession Type law is set to Strongest then this law will define what criteria is used to determine which empire is "the strongest".

  • Economy chooses the president based on economic power
  • Diplomatic Weight chooses the president based on diplomatic weight
  • Technology chooses the president based on technology level
  • Fleets chooses the president based on fleet power

Challenges[edit]

If the Succession Type law is set to Challenge then this law will define what the challenge for the choosing the next president will be. Empires that do not meet the challenge requirements will be forced to drop out from the competition.

Challenge Description Empire drops out if
