Mythology
According to Hesiod's Theogony, Tartarus was the third being to come into existence after Chaos and Gaea.

After Gaea gave birth to the Hecatoncheires and the Cyclopes, Uranus threw them into Tartarus because of their ugly appearance. Cronus promised his mother that he would release his siblings after overthrowing his father, however, he broke his promise and kept his siblings in their prison.

After Zeus overthrew his father, he imprisoned his father and uncles in Tartarus for fighting against him.
