Henry also gave Holland the Grote Waard (Dordrecht and its surroundings), at the cost of the bishopric of Utrecht.
He also set aside the Salic law for the succession to the County of Holland, which meant that it could be inherited by a female heir.
In 1196, Dirk temporarily gained the princely authority of the bishopric of Utrecht.
This meant war with Count Otto I of Guelders.
Otto was defeated at the Battle of the Grebbeberg.

William was supported by some of the West Frisians as well.
In 1202 Dirk allied himself with Otto of Guelders, and they both attacked Brabant.
