The Massacre at Béziers occurred on 22 July 1209 during the sack of Béziers by crusaders. It was the first major military action of the Albigensian Crusade.

The Albigensian Crusade or Cathar Crusade (1209–1229) was a military and ideological campaign initiated by Pope Innocent III to eliminate Catharism in Languedoc, what is now southern France. The Crusade was prosecuted primarily by the French crown and promptly took on a political aspect. It resulted in the significant reduction of practicing Cathars and a realignment of the County of Toulouse with the French crown. The distinct regional culture of Languedoc was also diminished.

This Pedro Berruguete work of the 15th century depicts a story of Saint Dominic and the Albigensians, in which the texts of each were cast into a fire, but only Saint Dominic's proved miraculously resistant to the flames.
