Boleslaus the Bashful

Boleslaus the Bashful, also called the Chaste (1226-1279), prince of Sandomierz, the son of Leszek the White, he assumed the throne in the Cracow province in 1243, having defeated Conrad of Mazovia. He failed to achieve his aims since the Sandomierz and Cracow provinces were invaded by the Mongols and attacked by Rus. In his foreign policy he relied on an alliance with Hungary, strengthened by his marriage with Kinga (Kunegunda), the daughter of the Hungarian king, Bela IV. He died leaving no heir. [art]
