The Würzburg witch trial, which took place in Germany in 1626–1631, is one of the biggest mass-trials and mass-executions seen in Europe during the Thirty Years War; 157 men, women and children in the city of Würzburg are confirmed to have been burned at the stake, mostly after first being beheaded; 219 are estimated to have been executed in the city proper, and an estimated 900 were killed in the entire Prince-Bishopric.
The Würzburg witch trial is among the largest Witch trials in the Early Modern period: it was one of the four largest witch trials in Germany alongside the Trier witch trials, the Fulda witch trials, and the Bamberg witch trials.
The first persecutions in Würzburg started with the consent of Julius Echter von Mespelbrunn, Prince bishop of Würzburg, and reached its climax during the reign of his nephew and successor Philipp Adolf von Ehrenberg. They started in the territory around the city in 1626 and evapourated in 1630. As so often with the mass trials of sorcery, the victims soon counted people from all society; also nobles, councilmen and mayors. This was during a witch hysteria that caused a series of witch trials in South Germany, such as in Bamberg, Eichstätt, Mainz and Ellwangen.
In the 1620s, with the destruction of Protestantism in Bohemia and the Electorate of the Palatinate, the Catholic reconquest of Germany was resumed. In 1629, with the Edict of Restitution, its basis seemed complete. Those same years saw, in central Europe at least, the worst of all witch-persecutions, the climax of the European craze.
