Final answer:
Philip II spent much of his energies during the late 16th century attempting to suppress a rebellion against his rule in the Netherlands.
Step-by-step explanation:
Philip II spent much of his energies during the late 16th century attempting to suppress a rebellion against his rule in the Netherlands. War raged from 1568 until a truce was signed in 1609, and the seven northern provinces established their independence from Spain as the United Provinces of the Netherlands. Additionally, Philip II launched a naval attack on England in 1588 to restore it to the Catholic Church and end its support for Protestant rebels in the Spanish Netherlands, but the invasion failed.
