General Notes
Henry was the eldest son of Duke Henry the Lion, from his marriage to Matilda, eldest daughter of King Henry II of England and Eleanor of Aquitaine. He grew up in England and became count palatine of the Rhine through his 1193 marriage to Agnes, heir to the Staufen count. When his younger brother Otto became one of two rival kings of the Holy Roman Empire in 1198, Henry at first supported him, but switched sides to Philip of Staufen in 1203. After he inherited significant properties in northern Germany from his brother William in 1213, he ceded the Palatinate to his son Henry, and moved north. He left his northern German properties to William's son, Otto. Henry died in 1227 and is entombed in Brunswick Cathedral.
