On October 11, 1274, Rudolf I of Bavaria, known as “the Stammerer,” was born in Basel. He became Duke of Upper Bavaria and Count Palatine of the Rhine from 1294 until 1317, navigating conflicts with his brother Louis IV and the Habsburgs before losing his power in 1317. His descendants continued to shape the Wittelsbach dynasty, which traced its origins to his Basel roots. See the Wikipedia entry for more information.
