Did cronus bary his children alive?

Yes, in Greek mythology, Cronus swallowed his children alive to prevent them from overthrowing him, as he had done to his father, Uranus. He feared that one of his offspring would eventually dethrone him, so he consumed each child immediately after their birth. However, his wife, Rhea, managed to save their youngest child, Zeus, by deceiving Cronus and hiding the baby. Zeus later led a rebellion against Cronus, ultimately freeing his siblings and defeating him.
