Otto IV of Scheyern

Otto IV of Scheyern (c. 1083–1156), second son of Count Eckhard I of Scheyern, accompanied Henry V on his Italian campaign of 1110–1111 and took part in the seizure of Pope Paschal II to force him to crown Henry emperor, for which Otto was excommunicated.

After his family moved its seat to Wittelsbach Castle near Aichach, he styled himself Otto of Wittelsbach from 1116, giving the dynasty its name. He became Count Palatine of Bavaria in 1120 and founded Indersdorf Abbey to atone for the papal kidnapping. His son Otto the Redhead became the first Wittelsbach Duke of Bavaria.
