Gaspar de Guzmán y Pimentel, 1st Duke of Sanlúcar, 3rd Count of Olivares, GE known as the Count-Duke of Olivares (taken by joining both his countship and subsequent dukedom) (January 6, 1587 – July 22, 1645), was a Spanish royal favourite of Philip IV and minister. As prime minister from 1621 to 1643, he over-exerted Spain in foreign affairs and unsuccessfully attempted domestic reform. His policy of committing Spain to recapture Holland led to a renewal of the Eighty Years' War while Spain was also embroiled in the Thirty Years' War (1618–1648). In addition, his attempts to centralise power and increase wartime taxation led to revolts in Catalonia and in Portugal, which brought about his downfall.
