Michele di Lando turned against them ignoring their demands, led to the third stage of the revolt. Reaction At the end of August 1378, factionalism among the Ciompi and the radical persecution of enemies of the revolution, led di Lando to arrest two Ciompi leaders who had demanded constitutional reform. The next day, di Lando rode out of the palace with the standard bearer of justice and cleared the piazza of a militia from the three new guilds who were shouting "Long live the popolo minuto" and demanding the resignation of di Lando's government. The workers' militia returned and a battle for the Piazza della Signoria broke out between the Ciompi and the forces of the major and minor guilds led by the guild of butchers. The Ciompi and Sotto posti were slaughtered that day by the other guilds alongside the reformist forces under previous Ciompi leader di Lando, who also acted to crush the Eight Saints who were attempting to challenge his power in government. This day has been named one of the bloodiest in Florentine history. On September 1, citizens assembled in the piazza and approved the dissolution of the Ciompi guild. Nevertheless, the government continued to enact Ciompi-led reforms, such as the establishment of the estimo—a direct tax on household wealth on October 29, 1378. Overall, the Ciompi revolt consisted of complex social, economic and political factors, as well as the involvement of more than one group of workers such as the Ciompi. The hierarchical guild system played an important part in the conflict, as did guild members who were key in turning on the government and ending its short reign over the city. Although often portrayed as radical today, the demands and wishes of the wool workers and others involved were fairly modest and reform did not take the shape of a societal overhaul. The idea that the Ciompi could live harmoniously with all the other groups and guilds in society after they assumed government, however, was idealistic. Furthermore, the disillusionment experienced when the conflict continued especially after the collapse of the regime and the guilds dissolution certainly contributed to the decline of labour unrest in Florence's cloth industry in the years following and lack of political power that these sections of society continued to have.
