Renaissance Humanism marked a shift from medieval thinking to a focus on human potential and classical learning. This movement, spanning the 14th to 17th centuries, began in Italy and spread across Europe, influencing art, literature, and philosophy. Key figures like Petrarch and Shakespeare shaped the era's literary landscape. The sonnet form evolved, reflecting humanist ideals of individual expression and exploration of love, beauty, and the human condition. This period's emphasis on reason and creativity laid the foundation for modern literature.
