CASIMIR III

born April 30, 1310, Kujavia, Pol. died Nov. 5, 1370 byname Casimir the Great, Polish Kazimierz Wielki king of Poland from 1333 to 1370, called the Great because he was deemed a peaceful ruler, a peasant king, and a skillful diplomat. Through astute diplomacy he annexed lands from western Russia and eastern Germany. Within his realm he unified the government, codified its unwritten law, endowed new towns with the self-government of the Magdeburg Law, and founded Poland's first university. Casimir was the second king of the reunited and resuscitated Poland that for nearly two centuries had been split into numerous small principalities. His father, Wladyslaw I, who had succeeded in reuniting Great Poland and Little Poland, renewed the long-forgotten kingship with his coronation in Krakw in 1320. During his own reign, Casimir would continue the work of his father, adding two large and important regions (Red Russia and Masovia) to the country and making it a solid and respected partner among the other 14th-century powers in central Europe. In addition, he would provide the country with a well-organized government, and thus so strengthened feelings of popular unity that after his death (although he left no legal heir) there were no attempts at restoring the former duchies and principalities. Casimir's mother was Jadwiga, daughter of Boleslaw the Pious (Pobozny) of Great Poland. After the death of his elder brother in 1312, Casimir was regarded as heir and was prepared for the kingship by Jaroslaw, later archbishop of Gniezno and Casimir's counsellor. Upon his father's death Casimir became king of Poland in 1333. Of his three sisters, one, Elizabeth, who in 1320 married King Charles Robert of Hungary, figured prominently in his foreign and dynastic policy. The Editors of the Encyclopdia Britannica
