The result of that bloody struggle was really a victory for the Arti Maggiori, the Arti Minori being bribed with promises and thus separated from the populace, who had sided with the Parte Guelfa, which was beaten for ever. The oligarchy was saved, but the struggle between rich and poor was by no means over. Soon the older Guilds seem to lose grip, and we see instead great trusts arising, associations of wealth, and above all, Banking Companies. What was wanting in Florence, as elsewhere in Italy, was some legitimate authority that might have guided the people in their desire for power. As it was, the city became divided into classes, each anxious to gain power at the expense of others, the result being an oligarchy, continually a prey to schism, merely waiting for a despot to declare himself. Seemingly in the hands of a group of families without any legitimate right, the government was really in the power of one among them, and thus of one man, the head of it, Maso degli Albizzi. Brilliant, clever, and fascinating, Maso ruled with a certain strength and generosity; but Florence was a city of merchants, and between the Scylla of oligarchy and the Charybdis of despotism, was really driven into the latter by her economic position. The Duke Gian Galeazzo of Milan closed the trade routes, and Florence was compelled to fight for her life. Pisa, too, had to be overcome, again for economic reasons, and in 1414 a long war with King Ladislaus brought Cortona into the power of the Republic; but all these wars cost money, and the taxes pressed on the poor, who obtained no advantage from them. Maso's son Rinaldo, who succeeded him before the wars were over, had less ability than his father, and was certainly less beloved; he seems, however, to have been upright and incorruptible. He was, nevertheless, capable of mistakes, and, while engaged in war with Milan, attempted to seize Lucca. At length, when the grumbling of the poor had already gone too far, he readjusted the taxes, and thus alienated the rich also. His own party was divided, he himself heading the more conservative party, which refused to listen to the clamour of the wealthier families for a part in the government, while Niccolo Uzzano, with the more liberal party, would have admitted them. Among these wealthy families excluded from the government was the Medici.
