Count-Duke of Olivares,
Caspar de Guzmán (1587-1645) Spanish nobleman and politician,
Duke of San Lücar. He was born in Rome where his father was an ambassador.
He was the favorite of Philip IV of Spain, and his prime minister for 22
years. He wrung money from the country to carry on foreign wars. His attempts
to rob people of their privileges provoked insurrections and roused the
Portuguese to shake off the Spanish yoke in 1640, and the king was obliged
to dismiss and exile him in 1643.
