Salvestro de’ Medici, who in 1370 had held the office of Gonfalonier, sought to put an end to the tyranny of party when he was again appointed Gonfalonier in the spring of 1378. The reigning faction, though mistrusting him, dared not oppose him, for fear of the multitude, who were in his favour. His attempt to diminish the authority of the Capitano and re-open the way to office to the excluded ones (_Ammoniti_) brought on a violent insurrection of the common people. This ‘tumulto dei ciompi,’ as it was called, placed Florence for a time under mob-rule, and would have degenerated into the wildest anarchy but for the energy of one poor man, Michele di Lando, the woolcomber, whom the infuriated populace had raised to the chief magistracy, and who, with remarkable instinct, steered the State safely through the storm which threatened its ruin. This state of things lasted three years, during which the all-powerful mob became the tool of designing men, who wreaked their vengeance on the party that had so lately been supreme. The latter, however, in their turn seized the opportunity when the better sort among the populace were disgusted with the tyranny of their fellows, and overthrew the mobocracy, setting up in its place a conservative government, formed of the _Optimates_, or better citizens, under the lead of the Albizzi. Salvestro de’ Medici, the original author of the revolt, contributed nothing to its suppression. It was, perhaps, beyond his power to do anything. He died in 1388, and the name of the Medici became identical with that of representatives of the interests of the people. Five years later, when the oppressions of the Albizzi had excited general discontent, an armed body of the people marched to the house of Vieri de’ Medici, and asked him to be their leader. He was of the same branch of the family as Salvestro, but he prudently declined the proposed honour, and appeased the revolters.
