Louis V, Duke of Bavaria

Louis V, called the Brandenburger (1315–1361), was the eldest son of Emperor Louis IV, who set him over Brandenburg as a boy. In 1323 the eight-year-old was enfeoffed with the march, ending the Brandenburg Interregnum. Defeat at Kremmer Damm in 1332 forced him to give up Pomerania.

In 1342 he married the Tyrolean heiress Margaret before her first marriage was dissolved, winning Tyrol but drawing excommunication. In 1347, while he was away in Prussia, Margaret beat back Charles IV's attack on Schloss Tirol, and that year he inherited Upper Bavaria.

In 1351, at odds with Brandenburg's nobles, he ceded the march to his half-brothers by the Treaty of Luckau. The Golden Bull of 1356 gave his Bavarian line no electoral vote. He died at Zorneding in 1361.
