Conscious of his power, and rejoicing in the imperial title, he had no idea of playing an obscure part on the conspicuous stage of European affairs. With an eagle eye he watched the condition of the empire, and no less eagerly did he fix his eye upon the movements of those great southern powers, now becoming consolidated into kingdoms and empires, and marshaling armies which threatened again to bring all Europe under a dominion as wide and despotic as that of Rome. Charles VIII., King of France, crossed the Alps with an army of twenty-two thousand men, in the highest state of discipline, and armed with all the modern enginery of war. With ease he subjugated Tuscany, and in a triumphant march through Pisa and Siena, entered Rome as a conqueror. It was the 31st of December, 1394, when Charles, by torchlight, at the head of his exultant troops, entered the eternal city. The pope threw himself into the castle of St. Angelo, but was soon compelled to capitulate and to resign all his fortresses to the conqueror. Charles then continued his march to Naples, which he reached on the 22d of February. He overran and subjugated the whole kingdom, and, having consolidated his conquest, entered Naples on a white steed, beneath imperial banners, and arrogantly assumed the title of King of Naples, Sicily and Jerusalem. Alphonso, King of Naples, in despair, abdicated in favor of his son, Ferdinand; and Ferdinand, unable to oppose any effectual resistance, abandoned his kingdom to the conqueror, and fled to the island of Ischia. These alarming aggressions on the part of France, already very powerful, excited general consternation throughout Europe. Maximilian, as emperor, was highly incensed, and roused all his energies to check the progress of so dangerous a rival. The Austrian States alone could by no means cope with the kingdom of France. Maximilian sent agents to the pope, to the Dukes of Milan and Florence, and to the King of Arragon, and formed a secret league to expel the French from Italy, and restore Ferdinand to Naples. It was understood that the strength of France was such, that this enterprise could only be achieved through a long war, and that the allies must continue united to prevent France, when once expelled from Italy, from renewing her aggressions. The league was to continue twenty-two years. The pope was to furnish six thousand men, and the other Italian States twelve thousand. Maximilian promised to furnish nine thousand. Venice granted the troops of the emperor a free passage through her dominions.
