BIOGRAPHY
Boleslaw was the second son of Wratislaw I, duke of Bohemia and Drahomira von Stodar. Boleslaw was duke of Bohemia from 929 to his death.

Boleslaw is notorious for the murder, possibly at the behest of his mother Drahomira, of his brother Wenceslas (later canonised as St. Wenceslas), the result of which brought him to the Czech ducal throne. Wenceslas was murdered during a feast on 28 September 929, on the day when Boleslaw's first son was born. He received the strange name of Strachkwas, which meant 'a dreadful feast'. Being remorseful for what he had done, Boleslaw promised to devote his son to religion and educate him as a clergyman. He kept his word.

Despite the fratricide, Boleslaw is generally respected by Czech historians as an energetic ruler. Citing Wenceslas' religious policies as the cause of Boleslaw's fratricide seems unlikely as Boleslaw in no way impeded the growth of Christianity in Bohemia, and in fact he actually sent his daughter Mlada, a nun, to Rome to ask permission to make Prague a bishopric.

One major policy shift after the death of Wenceslas related to Czech-German relations. It is usually asserted that Wenceslas was an obedient client of the German King Heinrich 'the Fowler'. Boleslaw, on the other hand, found himself almost immediately at war with Heinrich's successor Otto 'the Great'. This conflict, presumably consisting of border raids (the general pattern of warfare in this region at the time) between Boleslaw on one side and the margrave of the Ostmark on the other, reached its conclusion in 950 when Boleslaw signed a peace with Otto. It cannot be said for certain if Boleslaw became a vassal of the German king, but it is known that he led a Czech force in alliance with Otto at the great victory over the Magyars at the Lech river (on 10 August 955). He had also helped Otto to crush an uprising of Slavs on the Lower Elbe in 953.

Czech historians also claim that Boleslaw expanded his power into Silesia, Lusatia, and Moravia, but no dates are given for these alleged conquests. If they did occur, they must have been only transitory gains because Boleslaw's successors had to conquer them all over again. Boleslaw saw the growth of Polish strength to the north of his borders and he accordingly arranged for his daughter Dobrawa to marry the Piast prince Mieszko I in 965. Boleslaw died on 15 July 967 and was succeeded by his son Boleslaw 'the Pious'.
