Dirk VII, Count of Holland

Dirk VII of Holland (died November 4, 1203, Dordrecht), also known as Dietrich in German, Thierry in French, and Theodoric in English, was Count of Holland from 1190 to 1203. He was the elder son of Floris III and Ada of Huntingdon.

Thanks to a civil war in the Holy Roman Empire, Henry VI, Holy Roman Emperor had to find ways to make friends. The Emperor supported Dirk by giving him the right to levy tolls on Flemish traders in Geervliet. 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. In 1197 Dirk van Are was elected as the new bishop. As such, he recovered the princely authority of Utrecht. The Hohenstaufens were losing the civil war, so Count Dirk changed sides and gave his allegiance to the Welfs.

The Frisians in Oostergo and Westergo supported Dirk's brother William, who invaded Holland. 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. Brabant claimed Holland, Utrecht and Guelders as dukes of Lotharingia. Den Bosch and Geertruidenberg were sacked during this campaign. Duke Henry I of Brabant took Dirk prisoner at Heusden. As well as having to pay a high ransom, he had to accept the Duke of Brabant as his overlord in southern Holland and the Bishop of Utrecht as his overlord in northern Holland.

Dirk's daughter Ada inherited the County of Holland in 1203. She married Louis II, Count of Loon, who became Count of Holland.
