The Titans were best known for their war against the Olympian gods. Many of these gods were captive within the stomach of their father, Cronus. After Zeus, king of the Olympian gods, freed his siblings the war with the Titans began. After ten long years of battle Zeus asked Gaia for help. She told him to release the Cyclopes and the hundred-handed ones. This led to Crius and the other Titans losing the long war.
Crius was one of the Greek Titans. The Titans were the principal gods of early Greek mythology. Crius and his siblings were the children of Uranus (Sky) and Gaia (Earth). He had five brothers; Coeus, Cronus, Hyperion, Lapetus, Oceanus; and six sisters; Mnemosyne, Phoebe, Rhea, Tethys, Theia, and Themis.
