Rupert, King of Germany

Rupert of the Palatinate was born 5 May 1352 into the House of Wittelsbach. He became Elector Palatine in 1398 as Rupert III, one of the prince-electors who chose the Holy Roman Emperor. Two years later, in 1400, he was elected King of the Romans, the designation for a ruler of Germany who had not yet been crowned emperor by the Pope. He spent the next ten years navigating the fractured politics of the Empire, never achieving the imperial coronation that would have completed his claim. He died 18 May 1410, still holding the title he'd won but never fully realized.
