Why did Briareus help Zeus?

Briareus, one of the Hecatoncheires, helped Zeus during the Titanomachy because Zeus promised him freedom and a place of honor. After being imprisoned by Uranus, Briareus and his brothers were released by Zeus, who sought their immense strength to defeat the Titans. In gratitude for his liberation and the opportunity to fight against their common enemies, Briareus pledged his loyalty to Zeus. This alliance ultimately contributed to Zeus's victory and the establishment of his rule over the cosmos.
