What were the differences in ideology between John Locke and Thomas Hobbes?

Locke thought rulers could stay in power if they had the consent of those they governed. If the ruler was a tyrant, then the people had the right to rebel and set up a new government or appoint a new ruler.

Hobbes thought rulers should have absolute power. If people entered into such a contract, the people could not rebel, even if the ruler was a tyrant.
