HAGENBACH, PETER VON (c. Burgund ian courtier and governor of Alsace. A member of a noble family of the Sundgau, he was in 1453 in the service of Duke John I. of Cleves. After serving under various princes he joined the court of Charles the Bold (q.v.), duke of Burgundy, in 1469, and was made governor of the territories on the upper Rhine mortgaged to him by Sigismund of Austria. His government in Alsace was harsh and the towns of Rheingelden, Seckingen, Laufenburg and Waldshut rose in revolt against him. Other towns joined in the revolt. Hagenbach, who had no help from Charles except a few Picard soldiers, was seized on April Io, 1474, at Breisach, and imprisoned. Meanwhile Sigismund appeared at Basle to recover the mortgaged territories. The allies were determined on the death of the hated Hagenbach. He was tortured on May 5, and on May 9 was brought before a court at Breisach drawn from Strasbourg, Basle and other cities. He was condemned to death and beheaded the same evening.
