Who was the leader of the Titans and father of Zeus?

The story behind the answer

Cronus is correct: he was the youngest Titan who overthrew his father Uranus to become leader and then fathered the first Olympians—Hestia, Demeter, Hera, Hades, Poseidon, and Zeus. Fearing a prophecy that his children would dethrone him, Cronus swallowed them at birth, but Rhea hid baby Zeus, who later forced Cronus to disgorge his siblings and led the Olympians to victory in the Titanomachy.

Context check: Uranus was the sky and father of the Titans (not their leader), Prometheus
