In 1573 he was called by Philip II to succeed the Fernando Álvarez de Toledo, 3rd Duke of Alba as governor of the Spanish Netherlands, then in revolt against the Spaniards.He was rather moderate in comparison to Alba, requesting Philip to grant a general amnesty to all, with the exception of persistent heretics, and to permit the emigration of those who would not comply.In February 1574 the rebels had conquered the port of Middelburg, but Requesens's army obtained a victory against the troops of Louis of Nassau at the Battle of Mookerheyde, during which William the Silent's two brothers died.However, at this point the money for funding his troops was exhausted; Requesens had to find an agreement with William the Silent, the leader of the Flemish opposition, with the mediation of the Emperor Maximilian II.Requesens died suddenly at Brussels in 1576, to be replaced in the now totally chaotic Netherlands by John of Austria, half-brother of King Philip II of Spain.
