House of Wittelsbach - Reign in The Holy Roman Empire

Reign in The Holy Roman Empire

The Wittelsbach family was the ruling dynasty of the German territories of Bavaria from 1180 to 1918 and of the Electorate of the Palatinate from 1214 until 1805; in 1815 the latter territory was partly incorporated as Rhine Palatinate into Bavaria, which was elevated to a kingdom by Napoleon in 1806.

On Duke Otto II's death in 1253, the Wittelsbach possessions were divided between his sons: Henry became Duke of Lower Bavaria, and Louis II Duke of Upper Bavaria and Count Palatine of the Rhine. When Henry's branch died out in 1340 the duchy was reunited under Emperor Louis IV, a son of Duke Louis II.

The family provided two Holy Roman Emperors: Louis IV (1314–1347) and Charles VII (1742–1745), both members of the Bavarian branch of the family, and one German King with Rupert of the Palatinate (1400–1410), a member of the Palatinate branch.

The House of Wittelsbach split into these two branches in 1329: Under the Treaty of Pavia, Emperor Louis IV granted the Palatinate including the Bavarian Upper Palatinate to his brother Duke Rudolf's descendants, Rudolf II, Rupert I and Rupert II. Rudolf I this way became the ancestor of the older (Palatinate) line of the Wittelsbach dynasty, which returned to power also in Bavaria in 1777 after the extinction of the younger (Bavarian) line, the descendants of Louis IV.
