The friends of the king and those who opposed Lando and his followers, were either of noble families or the highest of the people, and all Guelphs; but their adversaries being in power they could not discover their minds without incurring the greatest danger. Being, however, determined to deliver themselves from such disgraceful tyranny, they secretly wrote to King Robert, requesting him to appoint for his vicar in Florence Count Guido da Battifolle. The king complied; and the opposite party, although the Signory were opposed to the king, on account of the good quality of the count, did not dare to resist him. Still his authority was not great, because the Signory and Gonfaloniers of the companies were in favor of Lando and his party. During these troubles, the daughter of King Albert of Bohemia passed through Florence, in search of her husband, Charles, the son of King Robert, and was received with the greatest respect by the friends of the king, who complained to her of the unhappy state of the city, and of the tyranny of Lando and his partisans; so that through her influence and the exertions of the king's friends, the citizens were again united, and before her departure, Lando was stripped of all authority and send back to Agobbio, laden with blood and plunder. In reforming the government, the sovereignty of the city was continued to the king for another three years, and as there were then in office seven Signors of the party of Lando, six more were appointed of the king's friends, and some magistracies were composed of thirteen Signors; but not long afterward the number was reduced to seven according to ancient custom.
