In order to comprehend the battle of Fornovo in its bearings on Italian history, we must go back to the year 1492, and understand the conditions of the various States of Italy at that date. On April 8 in that year, Lorenzo de’ Medici, who had succeeded in maintaining a political equilibrium in the peninsula, expired, and was succeeded by his son Piero, a vain and foolhardy young man, from whom no guidance could be expected.
