The Loon War (Dutch: Loonse Oorlog) was a war of succession over the County of Holland (and its dependency Zeeland) from 1203 until 1206, brought on by the death of count Dirk VII. The war was waged between Dirk's brother William of Frisia, and Dirk's daughter Ada who had quickly married count Louis II of Loon.
