'' (c. 1630-32), by
Anton van Dyck (
Museu de Belles Arts,
Valencia). Moncada served as the Spanish ambassador to the
Holy Roman Emperor between 1624 and 1629, and had a very good relationship with
Albrecht von Wallenstein. The Emperor
Ferdinand II was very impressed by him. He then served as a counselor to Princess
Isabella Clara Eugenia of Spain, regent of the
Spanish Netherlands. While serving in
Brussels he tried to convince King
Philip IV of Spain to transfer the general management of affairs in his Netherlands possessions to Brussels and remove any responsibility for such matters from the government in
Madrid. His proposals to give the various peoples in the Netherlands, still under
Habsburg rule, more say in their governmental affairs were rejected. He was made the commander-in-chief of the Spanish navy in the Netherlands in 1630. On 12–13 March 1631, his seamen under command of Count
Jan VIII van Nassau-Siegen, were defeated at the
Battle of the Slaak. In 1632 he was put in charge of all Spanish forces in the Netherlands. In 1634 he was made interim-governor of the
Spanish Netherlands on the death of
Spanish Netherlands Governess
Isabella Clara Eugenia in December 1633. During this period, he commissioned a seated and
equestrian portrait from Anthony van Dyck. He died in 1635 of a fever, caught at the successful siege of the
Schenkenschanz near
Goch,
North Rhine-Westphalia,
Germany, near the current Dutch-German border. ==Literary work==
