Władysław II the Exile
Władysław II the Exile (1105–1159), eldest son of Bolesław III Wrymouth, was high duke of Poland and duke of Silesia from 1138 under his father's settlement. His bid to centralize power brought war with his younger half-brothers; after he blinded their ally, the brothers expelled him from Poland in 1146.
He took refuge with his wife's imperial kindred and died in exile in 1159. His sons recovered Silesia in 1163, becoming the founders of the Silesian Piasts.
