I assume that you are asking about King Philip II of Spain as he is the most famous of the various rulers named Philip II. If so, Philip II was the king of Spain from 1556 to 1598. He was king during a time that Spain’s power was at its peak. Spain was getting huge amounts of wealth from its new colonies in the Americas. It controlled the Netherlands. It started to truly colonize the Philippines (named after Philip) during his reign. Philip is perhaps most famous in world history for ordering the disastrous attempted invasion of England by the Spanish Armada.
