Otto II, Duke of Bavaria

Otto II (7 April 1206 – 29 November 1253), called the Illustrious (German: der Erlauchte), was the Duke of Bavaria from 1231 and Count Palatine of the Rhine from 1228.

At the age of sixteen, he was married to Agnes of the Palatinate, a granddaughter of Duke Henry the Lion and Conrad of Hohenstaufen.

Since that time also the lion has become a heraldic symbol in the coat of arms for Bavaria and the Palatinate.

Otto acquired the rich regions of Bogen in 1240, and Andechs and Ortenburg in 1248 as possessions for the Wittelsbach and extended his power base in Bavaria this way.

The Annales sancti Rudberti Salisburgenses record her betrothal in 1235 to Conrad, who later married Elisabeth.
