Juan Domingo de Zuñiga y Fonseca

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.

This could not prevent Spain and its defences from playing a minor part in the following Franco-Dutch War (1672–1678).

In 1705 under the French king Philip V of Spain he left the State Council together with the Marquis of Mancera.

In 1710 his wife died without issue and Méndez de Haro decided to dedicate the rest of his life to God and became a Catholic priest.
