Floris immediately wanted to resume war, but King Edward I of England, who had an interest in access to the great rivers for wool and other English goods, convinced Floris to stop hostilities with Flanders. When in 1292 Floris claimed the throne of Scotland in the Great Cause (his great-grandmother Ada being the sister of King William I of Scotland), he did not receive the expected support from Edward, but England did support his claims in a new, this time more successful, war on Flanders.
