The Renaissance began in Italy, specifically northern Italian city-states like Florence, for several reasons: wealth from trade, powerful merchant class, and classical Greek/Roman heritage. Florence dominated the Italian Renaissance, with the Medici family as prominent patrons of the arts under figures like Cosimo and Lorenzo de' Medici. The Renaissance saw a rebirth of interest in classical works and humanism that focused on human potential and reason over religious tradition. This led to developments in realism and perspective in artistic works by figures like Michelangelo, Leonardo, and Raphael.
