Which titan ruled what?

In Greek mythology, the Titans were a group of powerful deities that ruled during the Golden Age. Cronus, the leader of the Titans, ruled over the universe until he was overthrown by his son Zeus, who then became the king of the gods and ruler of Mount Olympus. Other notable Titans included Oceanus, who ruled the ocean, and Hyperion, who was associated with the sun. The reign of the Titans ended with the Titanomachy, a great war between the Titans and the Olympian gods.
