Agnes of the Palatinate
Agnes of the Palatinate (1201–1267) was a daughter of the Welf Count Palatine Henry V and Agnes of Hohenstaufen. In 1222 she married Otto II Wittelsbach, a marriage through which the Wittelsbachs inherited the Palatinate and adopted the Palatine lion.
When Louis I died in 1231 she became duchess of Bavaria. Her five children included Louis II, father of Emperor Louis IV, Henry XIII and Elizabeth, wife of King Conrad IV. Agnes died in 1267 and was buried at Scheyern Abbey.
