When the commons were freed from the domination of the emperors, the feudal lords retained their power where they had sufficient land to preserve their pre-eminence. They shared or lost it from that or other causes, particularly from commerce, which brought other means of power to life which rivalled theirs. When these two kinds of nobles ceased to be rivals, they agreed in order to rule. The hatred of the people against the nobles hurried towns under the yoke of some of these powerful men, who had made it believed that they sincerely took the popular side. That is what cost the republic of Milan her proud liberty. In Genoa some ambitious nobles took the same means to preserve influence. The Dorias and Spinolas contracted an alliance with the people, and aided with feigned zeal in the introduction of democratic forms into the government. Other republics fell into an excess of distrust. Injustice nourished hatreds and deprived the state of its most illustrious citizens.[b] AN EMPEROR ONCE MORE IN ITALY On the 25th of November, 1308, the diet of Germany named Henry VII of Luxemburg as successor to Albert of Austria; and this election suddenly brought Italy back to the same struggle for her independence which she had so heroically supported against the two Fredericks. From the death of the second Frederick, fifty-eight years had passed since she had seen an emperor. Rudolf of Habsburg, Adolphus of Nassau, and Albert of Austria had too much to do in Germany to occupy themselves with this constantly agitated country, where they could demand obedience only with arms in their hands. Henry VII was a brave, wise, and just prince; but he was neither rich nor powerful. He secured to his son, by marriage, the crown of Bohemia, which had excited some jealousy among the Germans; and he believed it would be expedient, in order to avoid all quarrel in the empire, to quit it for some time. To flatter the national vanity, he determined on an expedition to Italy. Henry, himself a Belgian, had no power but in Belgium and the provinces adjoining France. From Luxemburg he went through the county of Burgundy to Lausanne. Here he received, in the summer of 1310, the ambassadors of the Italian states, who came to do him homage. He entered Piedmont, by Mont Cenis, towards the end of September, accompanied by only two thousand cavalry, the greater part of whom were Belgians, Franc-Comtois, or Savoyards. This force would have been wholly insufficient to subdue Italy; but Henry VII presented himself there as the supporter of just rights, of order, and, to a certain degree, of liberty.
