Philip ll of Spain (1527-98)

Hapsburg monarch
The Hapsburg king of Spain, Philip II used his position to promote the Catholic Counter-Reformation. Too mistrustful to delegate, he ruled autocratically, miring his empire in a bureaucracy that exacerbated his own indecisiveness.
Before he was king of Spain, Philip was married to Mary Tudor, queen of England, daughter of Henry VIII and half sister to Elizabeth I. In 1556 he inherited Spain, its dominions in Italy and the New World, and the Netherlands. Announcing "I do not propose nor desire to be the ruler of heretics," he set out to impose Catholicism through force and the brutal means of the Inquisition, exiling Christianized Muslims from Granada and fighting to crush Protestantism in the Netherlands, England, and France. The "Invincible Armada," sent to invade and convert England was destroyed by a storm, adding to huge costs that crippled the state.
Despite this, the Spanish Empire reached its greatest extent and power during Philip's reign and his magnificent palace, El Escorial, in which he died, is one of Europe's greatest architectural monuments.
