Our modern world begins with the Protestant Reformation. The term itself is objected to by Catholics, who claim that there was little real reform. But the importance of the event, whether we call it reform or revolution, is undenied. Previous to 1517 the nations of Europe had formed a single spiritual family under the acknowledged leadership of the Pope. The extent of the Holy Father's authority might be disputed, especially when he interfered in affairs of state. Kings had fought against his troops on the field of battle. But in spiritual matters he was still supreme, and when reformers like Huss and Savonarola refused him.
