Albigensian Crusade

In this episode, we focus on the Albigensian Crusade, the brutal twenty-year campaign launched by Pope Innocent III to destroy the Cathar movement in southern France. We examine how the Cathars’ dualist beliefs and rejection of the Catholic Church’s authority made them a target for both religious condemnation and military violence. The episode also explores how northern crusaders and French royal forces used the conflict to crush resistance in Languedoc, transforming a spiritual campaign into a major political conquest. Beyond the war itself, we look at the rise of the Medieval Inquisition, which helped eliminate the remaining Cathar presence through preaching, investigation, and prosecution. Ultimately, the Albigensian Crusade reshaped southern France and remains deeply controversial for the scale of its violence and the lasting debate over whether it can be understood as an early form of genocide.
