Francis I was a significant monarch of the Valois dynasty who reigned as King of France from 1515 until his death in 1547. He was a great patron of the arts, initiating the French Renaissance by attracting many Italian artists to work for him, including Leonardo da Vinci. His reign was marked by intense rivalry with Holy Roman Emperor Charles V, leading to a series of wars for control of Italy and other territories. Despite military setbacks, his cultural and architectural legacy, such as the Château de Chambord, profoundly shaped French national identity.
