Casimir

Casimir, the name or title of many Polish princes. Casimir I., in 1041, made Christianity the prevailing religion of Poland, and Casimir III. - called the Great (1333-1370) - did much for his country. He founded a university, schools, and hospitals, and showed such regard for the lower classes of his subjects as won for him the title of King of the Peasants. He also greatly befriended the Jewish race out of love for his Jewish mistress. He drove back the Tartars who were threatening his kingdom, and added the Little and Red Russias to his territory.
