a Spanish military and political figure. In 1667 Méndez de Haro went to the Spanish Netherlands, where he became Captain General of the Cavalry in 1669. In 1670 he was appointed Governor of the Habsburg Netherlands and Captain General in the absence of Don John of Austria the Younger. In 1671, when war threatened between France and the Netherlands, Spain allied itself to the Netherlands and Méndez de Haro became Spanish supreme commander in the North. He organised defences, fortifying the Spanish fortresses along the French border.
