Who was the King of Poland during the 1100's?
Kingdom of Poland (1025–1385)
Duke Bolesław III the Wrymouth, who reigned from 1102 to 1138, tried to end the repeated struggles between various claimants by setting the government of Poland on a more formal footing. In his testament, he divided his lands into five Duchies and distributed them among his sons.
History of Poland
Poland was established as a state under the Piast dynasty, which ruled the country between the 10th and 14th centuries. Historical records referring to the Polish state begin with the rule of Duke Mieszko I. Mieszko, whose reign commenced sometime before 963 and who continued as the Polish monarch until his death in 992, chose to be baptized in the Western Latin Rite, probably on 14 April 966, following his marriage to Princess Doubravka of Bohemia, a fervent Christian. This event has become known as the baptism of Poland, and its date is often used to mark a symbolic beginning of Polish statehood. Mieszko completed a unification of the West Slavic tribal lands that was fundamental to the new country's existence. Following its emergence, Poland was led by a series of rulers who converted the population to Christianity, created a strong kingdom and fostered a distinctive Polish culture that was integrated into the broader European culture.
