History
The period of fragmentation of Poland began in 1138, after the Testament of Bolesław III Krzywousty. According to the testament, Duke Henry of Sandomierz was granted the Land of Sandomierz. Since the duke was too young, the newly created province was temporarily ruled by High Duke Władysław II the Exile. In 1146, after another conflict with the junior dukes, Wladyslaw II was forced to flee abroad, and the Duchy of Sandomierz was transferred to Henry.
Henry died in 1166, killed by the Old Prussians. Since he was childless and had no wife, part of his province, with Wislica, was inherited by his youngest brother, Casimir II the Just, while Sandomierz was seized by Bolesław IV the Curly. The province remained divided until 1173, when Casimir II the Just reunited it.
