Dirk VII of Holland (d. 1203), Count of Holland from 1190 to 1203. He was elder son of Floris III and Ada of Scotland. There was civil war in the Holy Roman Empire, so the emperor had to give to make friends. Henry VI, Holy Roman Emperor supported Dirk by giving him the right to levy toll on Flemish traders in Geervliet. Henry also gave the Grote Waard (Dordrecht and surroundings) to Holland at the cost of the bishopric of Utrecht. He made Holland inheritable for females. Wikipedia
