Significant changes in social structures during the Renaissance were driven by a renewed interest in humanism, leading to shifts in art, science, and philosophy. The rediscovery of classical texts spurred advances in various fields, encouraging a focus on individual potential and human achievement. Additionally, the rise of the merchant class, influenced by trade and exploration, undermined established feudal systems and contributed to the growth of urban centers. This transformative period marked the transition from medieval to modern thought, impacting societal norms and paving the way for future intellectual movements.
