In Greek mythology, the Titans and Titanesses were members of the second generation of divine beings, descending from the primordial deities and preceding the Olympians. Based on Mount Othrys, the Titans most famously included the first twelve children of Gaia (Mother Earth) and Uranus (Father Sky). They ruled during the legendary Golden Age, and also comprised the first pantheon of Greek deities.
The first twelve Titans were the females Mnemosyne, Tethys, Theia, Phoebe, Rhea, and Themis and the males Oceanus, Hyperion, Coeus, Cronus, Crius, and Iapetus. They begat more Titans: Hyperion’s children Helios, Selene, and Eos; Coeus’ children Leto and Asteria; Iapetus’ sons Atlas, Prometheus, Epimetheus, and Menoetius; Oceanus’ daughter Metis; and Crius’ sons Astraeus, Pallas, and Perses. Just as Cronus overthrew his father Uranus, the Titans were overthrown by Cronus’s children (Zeus, Hades, Poseidon, Hestia, Hera and Demeter), in the Titanomachy (or “War of the Titans”).
Cronus is the youngest of the Titans, son of Ouranos and Gaia. Kronos’ father, Ouranos, who was jealous of all his sons, threw them back into the depths of the earth (Tartaros). Kronos’ mother Gaia wanted revenge and urged Kronos to castrate his father, which Kronos did with a sickle. He then became ruler in place of his father. He married his sister Rhea, but he didn’t want any of the children from this marriage alive since his parents had predicted that one of those children would take his rule away. As soon as the children were born, he devoured them with skin and hair.
