Florence soon became tired of Savonarola. The city had become an unhappy place to live. Savonarola's promises that God would change things in the city did not come true, and his predictions of the end of the world did not happen. During his Ascension Day sermon on May 4, 1497, groups of young men rioted in the streets, people began singing and dancing, and the taverns reopened. The riot became a revolution.
