In Greek mythology, the Titans (Greek: Τιτάν—Ti-tan; plural: Τιτᾶνες—Ti-tânes) were a primeval race of powerful deities, descendants of Gaia (Earth) and Uranus (Heaven), that ruled during the legendary Golden Age. They were immortal huge beings of incredible strength and stamina and were also the first pantheon of Greco-Roman gods and goddesses.
In the first generation of twelve Titans, the males were Oceanus, Hyperion, Coeus, Cronus, Crius and Iapetus and the females - the Titanesses - were Mnemosyne, Tethys, Theia, Phoebe, Rhea and Themis. The second generation of Titans consisted of Hyperion's children Eos, Helios, and Selene; Coeus's daughters Leto and Asteria; Iapetus's sons Atlas, Prometheus, Epimetheus, Calypso and Menoetius; Oceanus' daughter Metis; and Crius's sons Astraeus, Pallas, and Perses.
The Titans were overthrown by a race of younger gods, the Olympians, in the Titanomachy ("War of the Titans"). This represented a mythological paradigm shift that the Greeks may have borrowed from the Ancient Near East
