French–Breton War
From Warlike
The French–Breton War lasted from 1487 to 1491. The cause of this war was the approaching death of the Breton Duke Francis II of Brittany, who had no clear successor. If not resolved, this meant a resumption of issues from a previous War of the Breton Succession (1341–1364), which had rival claimants allying with England or France, resulting in an ambiguous peace treaty that failed to prevent future succession disputes.
