In Greek mythology, the Titanomachy (, ) was a ten-year series of battles fought in Thessaly, consisting of most of the Titans (an older generation of gods, based on Mount Othrys) fighting against the Olympians (the younger generations, who would come to reign on Mount Olympus) and their allies. This event is also known as the War of the Titans, Battle of the Titans, Battle of the Gods, or just the Titan War. The war was fought to decide which generation of gods would have domain over the Universe; it ended in victory for the Olympians.
