Boleslaus I (the Gruesome) Duke of Bohemia ²⁰¹

  Notater:

Boleslaus I the Cruel, also called Boleslav I (Czech: Boleslav I. Ukrutný) (c.915 - 15 July, 967 or 972), was the ruler (kníže, "duke" or "prince") of the Duchy of Bohemia from 935 to his death. He was the son of Vratislaus I and the younger brother of his predecessor, Wenceslaus I.

Boleslaus is notorious for the murder of his brother Wenceslaus, through which he became Duke of Bohemia. According to tradition, Wenceslaus was murdered during a feast at precisely the time when a son of Boleslaus was born. The child was given a strange name: Strachkvas, which means "a dreadful feast". Remorseful for what he had done, Boleslaus promised to have his son educated as a clergyman and devote his life to religion.

Boleslaus blev gift med Biagota von Stockow.
