Diplomacy between plantoids and arthropoids

Diplomacy in Stellaris draws on the model of previous Paradox games and offers an alternative to warmongering. It should be noted that the dialogue at the initial contact screen has no effect on opinion or further diplomacy.

Envoys

Envoys are minor Leaders and can be assigned to various diplomatic tasks. Once an Envoy is assigned to a task it cannot be reassigned again for a year. Envoys can be assigned to the following tasks:

  • Improve Relations with another empire, which grants +1 Diplomacy opinion.png Opinion per month to and from the target empire (up to +200) and removes the Relation requirement for positive diplomatic actions
  • Harm Relations with another empire, which grants -1 Diplomacy opinion.png Opinion per month to and from the target empire (up to -200) and removes the Relation requirement for negative diplomatic actions
  • Assign to the Federation, which grants by +1 Federation cohesion.png Cohesion per month to the Federation
  • Assign to the Galactic Community, which grants +10% Diplomatic weight.png Diplomatic Weight

Diplomatic Actions

Many diplomatic actions have a 10-year cooldown once chosen. Some of these are unilateral while others need to be accepted by both sides which becomes a matter of acceptance. Most diplomatic actions require certain Relations or an envoy being sent to improve or harm Relations.

Maintaining any form of lasting treaty generates Diplomacy trust.png Trust, which increases Diplomacy opinion.png Opinion. The maximum amount of Trust obtainable is limited by the most valuable treaty between both parties. Finishing the Diplomacy tradition tree grants +50 trust cap. Trust decays if there is no new income.

Agreements

Agreements are mutually-beneficial diplomatic actions that when offered by an empire the other must accept for them to take effect. Agreements can be ended at any time by either empire but will bring a temporary Diplomacy opinion.png Opinion malus.

Agreements and Ethics Attraction

Some diplomatic relationships affect the ethics attraction within an Empire. Running deals can have a great impact, based on the empire ethics of the other party - always dragging their own population towards a certain Ethic. The wrong friend can cause internal issues for an Empire.

  • War: Militarist.png Militarist
  • Rivalry: Militarist.png Militarist
  • Defensive Pact, Federation, or Migration Access: Egalitarian.png Egalitarian, Xenophile.png Xenophile, Spiritualist.png Spiritualist
  • Research Agreement: Materialist.png Materialist
  • Subject: Spiritualist.png Spiritualist if the overlord is spiritualist too

Genocidal Diplomacy

Empires with the Civic fanatic purifiers.png Fanatic Purifiers civic can only engage in diplomacy with empires of the same primary species. Sharing the civic is not necessary although if they do it grants +200 Diplomacy opinion.png Opinion.

Empires with the Civic machine terminator.png Determined Exterminator civic can only engage in diplomacy with empires with Auth machine intelligence.png Machine Intelligence authority or the Ap synthetic evolution.png Synthetic Evolution Ascension Perk.

Empires with the Civic devouring swarm.png Devouring Swarm or Terravore civics cannot engage in diplomacy at all, not even with identical empires.

Favors

Favors can be traded via diplomatic trade or obtained through events and have two purposes. First, an empire can call upon Favors to add another empire's Diplomatic Weight to theirs when voting Resolutions in the Galactic Community as long as they don't already vote identically. Second, Favors increase the acceptance rate of certain diplomatic agreements or federation laws by +5 for each Favor. An empire can owe another empire up to 10 Favors.

Multiple empires can call upon Favors from the same target empire.

Attitude

Each empire will have a specific attitude towards other empires dictated by their AI personality, diplomatic interactions and the relative power of both empires.
