Conrad, Count Palatine of the Rhine

Conrad of Hohenstaufen was count palatine of the Rhine from 1156 until his death in 1195, a half-brother of Emperor Frederick Barbarossa. He built up a territorial base around Heidelberg, Alzey and the lower Neckar, laying the foundation of the later Electoral Palatinate. Through his daughter Agnes, who married Henry of Brunswick, son of Henry the Lion, the palatinate passed to the Welfs.
