In the year 1340, new sources of disagreement arose. The great had two ways of increasing or preserving their power; the one, so to restrain the emborsation of magistrates, that the lot always fell upon themselves or their friends; the other, that having the election of the rectors, they were always favorable to their party. This second mode they considered of so great importance, that the ordinary rectors not being sufficient for them, they on some occasions elected a third, and at this time they had made an extraordinary appointment, under the title of captain of the guard, of Jacopo Gabrielli of Agobbio, and endowed him with unlimited authority over the citizens. This man, under the sanction of those who governed, committed constant outrages; and among those whom he injured were Piero de' Bardi and Bardo Frescobaldi. These being of the nobility, and naturally proud, could not endure that a stranger, supported by a few powerful men, should without cause injure them with impunity, and consequently entered into a conspiracy against him and those by whom he was supported. They were joined by many noble families, and some of the people, who were offended with the tyranny of those in power. Their plan was, that each should bring into his house a number of armed men, and on the morning after the day of All Saints, when almost all would be in the temples praying for their dead, they should take arms, kill the Capitano and those who were at the head of affairs, and then, with a new Signory and new ordinances, reform the government.
