The history of the world’s great religions is often written in blood. This documentary explores the complex relationship between faith and violence, from the triumphant expansion of Islam and the devastating Mongol invasion of Baghdad in 1258, to the motivations behind the Crusades. We investigate key concepts like Jihad and the surprising cultural exchange between Muslim and Christian knights. Finally, we examine how the Christian-on-Christian brutality of the Thirty Years’ War led directly to the formation of the modern, secular state, changing the balance of religious and political power forever.
