Rupert (d. c.710), bishop of Worms and Salzburg. Frankish or possibly Irish by birth, he founded the monastery of St. Peter at Salzburg and the nunnery at Nonnberg, where his sister Ermentrude became abbess. He then acted as a missionary bishop in the Danube area with notable success. Later he evangelized and preached at Regensburg (Bavaria). Near Salzburg he developed the salt-mines, for which reason his iconographical emblem is a barrel of salt. Many churches in this area are dedicated to him. Feast: 27 March.

1352–1410, German king (1400–1410), elector palatine of the Rhine. He was elected German king after the deposition of Wenceslaus. Seeking the imperial crown, Rupert went to Italy. He attempted to intervene in Italian affairs and regain the former imperial city of Milan from Gian Galeazzo Visconti, but he was defeated and returned impoverished to Germany in 1402. Recognized (1403) by the Roman Pope Boniface IX, he adhered to the Roman popes in the Great Schism. When he sent envoys to plead for Gregory XII at the Council of Pisa, the council refused to recognize his title. Rupert was unable to exercise any control over the warring cities and nobles. At his death, two successors were elected, but in 1411 he was succeeded by Sigismund.
