Bolesław II the Horned

Bolesław II the Horned (c. 1220–1278) was a Silesian Piast, son of Henry II the Pious. He succeeded when his father fell fighting the Mongols at Legnica in 1241, but soon lost Kraków and other lands. In 1248 he divided Lower Silesia and took Legnica.

He was excommunicated for jailing the Bishop of Wrocław and did penance in 1261. In 1277, allied with Rudolf of Germany, he captured Henry IV of Wrocław and won at Stolec. He died in December 1278, leaving Henry V, Bolko I and Bernhard; his son Henry V succeeded him.
