Agnes of Hohenstaufen
Agnes of Hohenstaufen (1176–1204) was the daughter and heiress of Conrad, Count Palatine of the Rhine. To reconcile Staufen and Welf, she was betrothed as a child to Henry, eldest son of Henry the Lion.
When Emperor Henry VI instead planned to wed her to King Philip II of France, her mother Irmengard married the pair in early 1194. From 1195 she ruled the Palatinate with Henry, and bore the future Count Palatine Henry VI and two daughters.
