== 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 as well as meeting an additional ethic, authority, civic, or completed tradition tree requirement.

=== 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|ink=Planetary_features#Federation Monument]] 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|link=Starbase#Offworld Trading Company]] 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}}
