The War of the Cow (1272–78), in French Guerre de la Vache, is a conflict between the Prince-Bishopric of Liège under Bishop John of Enghien and the Marquisate of Namur under Marquis Guy of Dampierre.
What begins as a dispute over stolen property between a peasant from one jurisdiction and a burgess from another becomes a major regional conflict requiring the arbitration of King Philip III of France, who orders the restoration of the status quo ante bellum in 1278.
