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.
