The Titans are the older kind of gods in Greek mythology. The original Twelve Titans were children of Gaia (Mother Earth) and Uranus (Father Sky). Their leader was Cronus, who overthrew his father Uranus and became ruler of the gods. Cronus' consort was his sister Rhea. Their children were Zeus, Hades, Poseidon, Hera, Demeter and Hestia. Cronus and the Titans were overthrown by Zeus, his youngest son. They fought a war called the Titanomachy. The Titans are depicted in Greek art less often than the Olympians.
