(born May 1, 1218, Limburg-im-Breisgau—died July 15, 1291, Speyer) First German king (1273–91) of the Habsburg dynasty. He inherited lands in Alsace, the Aargau, and Breisgau and extended his territory by marriage and through negotiation. Crowned king in 1273, he was recognized by Pope Gregory X only after promising to lead a new Crusade and to renounce imperial rights in Rome, the papal territories, and Italy. Rudolf defeated his rival Otakar II (1276, 1278) and gained lands in Austria, which he granted to his sons. He worked to combat the expansionist policies of France, but French influence at the papal court kept him from being crowned Holy Roman emperor. Although he created the core of later Habsburg territorial power, Rudolf was unable to make the throne a hereditary possession of his family, because the German electors would not raise his son to the kingship.

A civil war against his brother Louis IV due to new disputes on the partition of their lands was ended in 1313, when peace was made at Munich. Louis IV was elected German king in 1314 but Rudolf had voted for his opponent Frederick of Austria. In 1317 after another long controversy with Louis IV he lost the Palatinate and it was agreed that Rudolf gave up his rule until the conflict of Louis with Habsburg was ended. But then Rudolf died already in 1319, assumedly in England.
But by the Treaty of Pavia in 1329, Louis granted the Palatinate to Rudolf's sons Rudolf II "the Blind" and Rupert I and Rudolf's grandson Rupert II, a son of Adolf. This way finally Rudolf I and his grandson Rupert II became the ancestors 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.
