Margaret of Bohemia
Margaret of Bohemia (21 February 1296–8 April 1322) was a daughter of King Wenceslaus II of Bohemia. Betrothed by her father to Bolesław III the Generous, Duke of Legnica and Brzeg, she married him in 1308.
The match gave Bolesław a claim to the Bohemian crown after the Přemyslid dynasty died out in 1306, although the crown passed to John of Luxembourg. She died on 8 April 1322, one day after giving birth to her youngest son Nikolaus; her surviving sons were Wenceslaus I and Louis I the Fair.
