In the vast expanse of the cosmos, borders are mere lines drawn on a map. Ideas, on the other hand, have no such limits. Your empire was founded on its Ethics. In Stellaris: Willpower, those values evolve into Ideologies with the power to sway the stars, turning your beliefs into a galactic force. Your Ideology can rally entire civilizations, but it can also turn inward. If your authority weakens, colonies may radicalize and rise against you.
The galaxy is ready to believe. What will you teach?
Unlock the complete 2026 roadmap for Stellaris! The Stellaris: Season 10 Expansion pass is a journey through resilience and movement.
Whether you are wandering the stars with Stellaris: Nomads or rooting your empire in the indomitable spirit of Stellaris: Willpower, this year redefines how empires survive, adapt, and conquer.
An Ethic backed with fanatic conviction can become an Ideology that crosses borders. Once you establish your Ideology, you can start spreading it across neighboring systems using Starbases, Hyper Relays, and Ideological Beacons into other Empires.
Foreign populations may adopt your values, forming Fanatic Factions corroding your enemies from within. However, staying true to your values becomes critical as you spread your Tenets across the Galaxy. Without an eye for your Momentum, internal factions might start revolting as they demand you stay true to your values.
A relocatable Galactic Hall gives your Ideology a visible place on the galactic map. Above a colony, it strengthens local output and Ideological Reach. At the frontier, it carries your message into contested space.
Galactic Halls come with a design for every Ethic (yes, there is a biological one too!).
Who says winning the galaxy requires conquering it?
Discover a different route to victory: make the Galaxy follow you, and defeat all the Fallen Empires. Convert populations, draw other empires into your orbit, and sustain the Momentum that fuels your Willpower. As your Ideology spreads across the Galaxy, prove that yours are the ideas that will save everyone from the threats of the Fallen Empires.
Ideological power extends into diplomacy. Empires can adopt your doctrine, and Federation laws can establish an official belief for the alliance. The same struggle reaches the Galactic Community, where you can denounce rival doctrine.
Espionage Operations can manipulate Ideological Reach, sow doubt, and incite revolt where your beliefs have already taken hold. If covert pressure fails, a new Casus Belli will allow you to impose your Ideology through war. It is still persuasion, only with more battleships.
