The Titans (Greek: Τiτᾶνες, Titânes - "Straining ones") were members of the second generation of immortal beings in Greek mythology. Though many beings were referred to as Titans in the myths, the term is usually used in reference to the twelve children of Gaia and Ouranos.
They ruled the cosmos prior to the Olympians, with whom they fought for control of the universe in a series of battles known as the Titanomachy. The Olympians emerged victorious, as many of the Titans were cast into Tartarus.
