Bolesław III the Generous

Bolesław III the Generous (1291–1352), eldest son of Henry V the Fat, was Duke of Legnica, Brzeg and Wrocław from 1296. He married Margareta, daughter of Wenceslaus II of Bohemia, and after the Přemyslids died out in 1306 claimed the Bohemian crown: he took Opava in 1308 but renounced his claim at Olomouc in 1311.

The 1311 division left him Brzeg, and he could not retake Wrocław from his brothers. He became a Bohemian vassal in 1329, and in 1342 abdicated Legnica to his sons Wenceslaus I and Louis I, retiring to Brzeg.
