Rhea plotted against her husband
Uranus, Cronus's father, foresaw that his offspring would depose Cronus. Cronus began swallowing all of his children one by one out of fear of this prophecy. All five of his firstborn children were devoured by him. Mother Rhea was worried about being childless if she couldn't save her final child. Zeus was the last-born and youngest child.
The Goddess sought advice from her mother, Gaia, to protect him from Cronus. Gaia showed her a secret. She gave Cronus a stone wrapped in fabric that resembled a newborn when he requested for the last-born child. Cronus relaxed about the prophecy since he believed he had ingested all of his children. But Zeus was covertly brought to Crete by the goddess Rhea.
She needed assistance from her companions, the swashbuckling Kouretes and Dactyls, to get to Crete. They served as the baby Zeus' protector. She gave Amalthea and other nymphs the responsibility of looking after him in Crete. After leaving her kid behind in Crete, she went back to Cronus. Zeus was raised in Mount Ida's Dictean Cave.
She enlisted the aid of Metis and fooled Cronus into consuming a poisoned beverage at Zeus' return to Rhea. He drank, which caused him to expel everything in his stomach. One by one, every child he had swollen started to emerge. The final kid to emerge from Cronus' womb was Hestia. Zeus and his siblings intended to depose Cronus and give the new regime the name Titanomachy.
