Pax Historia

Pax Historia is a Y Combinator-backed company that the first AI-powered grand strategy platform. The company participated in the Winter 2026 batch of Y Combinator.

Pax Historia is an alternate-history sandbox game where players choose a country, a moment in time, and rewrite the course of history. What if Rome never fell? What if the Soviet Union survived? What if Genghis Khan ruled for another generation?

We go beyond history, too.

Pax Historia was part of Y Combinator's Winter 2026 cohort, has a team of approximately 3 employees, and is actively operating.
