The trial of Joan of Arc began in Rouen, France, on January 9, 1431, before an ecclesiastical court presided over by Bishop Pierre Cauchon. The trial was conducted by an English-backed church tribunal on charges of heresy, which included wearing men's clothes and acting on what the court claimed were demonic visions.
The trial concluded with Joan being burned at the stake on May 30, 1431. The verdict was later overturned in 1456 after a reinvestigation found the original trial was "tainted by deceit and procedural errors".
