Stephen III of Bavaria

Stephen III (1337–1413), called the Magnificent, was the eldest son of Duke Stephen II of Bavaria and Elizabeth of Sicily. From 1375 he ruled Bavaria jointly with his brothers, until the 1392 partition gave him Bavaria-Ingolstadt, where he founded the Ingolstadt line.

He repeatedly fought his brothers and nephews over their shares, supported King Rupert against the Luxemburgs, and backed the failed Munich citizens' uprising of 1403. His daughter Isabeau married Charles VI of France. A final bid to reconquer Tyrol in 1410 failed, and he died at Niederschönenfeld in 1413.
