In the summer of 1378, the streets of Florence witnessed an unprecedented episode in medieval history: the Ciompi revolt, a popular uprising led by the poorest textile workers in the city. Marginalized from political life and exploited by powerful guilds, the Ciompi decided to take their destiny into their own hands, altering the balance of power in one of the most influential republics of the time.
Florence in the 14th century was one of the wealthiest city-states in Europe, driven by its thriving textile industry and international trade. However, this wealth was concentrated in the hands of a merchant elite that controlled the guilds and politics. The Florentine economy was dominated by large families of bankers and merchants, such as the Medici and Albizzi, who monopolized institutions of power. Meanwhile, the Ciompi, wage workers involved in wool carding and dyeing textiles, lacked representation within the guild system and lived under exhausting working conditions. According to Martines (2003, p. 214), "the Florentine oligarchy not only governed but also designed mechanisms to exclude the working classes from power."
The economic crisis and consequences of the Black Death had exacerbated the situation for workers. The plague, which ravaged Europe between 1347 and 1351, caused a drastic reduction in population and altered the economy. While in some regions this led to improvements in working conditions due to labor shortages, in Florence the elite imposed strict regulations to keep wages low and increase their profits. As Cohn (2006, p. 92) notes, "the economic difficulties following the Black Death increased inequality and despair among workers."
Moreover, the Florentine government implemented fiscal policies that disproportionately affected the less fortunate. Indirect taxes such as levies on bread and other basic goods increased the precariousness of workers' lives. The Signoria, Florence's governing body, systematically ignored requests for social and political reforms, increasing resentment among lower classes.
Popular discontent erupted in June 1378. The initial spark was a series of protests against corruption and abuses by the major guilds, particularly those linked to the textile industry. The Ciompi, supported by other disadvantaged sectors of the population, took to the streets of Florence and succeeded in overthrowing the city government. The revolt reached its peak when the Palazzo della Signoria, the center of Florentine political power, was occupied by insurgents.

For several weeks, workers established an unprecedented regime where they had a voice in politics. Under the leadership of Michele di Lando, a former wool carder, they succeeded in recognizing new guilds for unrepresented workers and approving reforms to improve their conditions. Brucker (1977, p. 143) describes this moment as "one of the few occasions in medieval history when manual laborers achieved real political influence."
The political organization of the Ciompi, however, was not exempt from internal conflicts. Not all sectors of the revolt had the same aspirations, and soon divisions emerged between skilled artisans and poorer workers. These tensions weakened the movement and facilitated its subsequent repression. In August 1378, the reaction of the merchant elite was brutal. With support from more affluent sectors and backing from other guilds, they organized a counter-revolution that crushed the revolt. Leaders were hunted down and executed, and concessions won were revoked. The Florentine oligarchy regained control and punished the Ciompi, ensuring they would not pose a threat again. As Najemy (2006, p. 211) highlights, "the Ciompi revolt ended up being a reminder of the fragility of alliances between different social strata."

The restoration of order meant the reinstatement of the old guild system, reinforced with measures to prevent new insurrections. Additional restrictions were implemented to limit worker organization and surveillance over popular sectors was intensified.
The Ciompi revolt left an indelible mark on Florence's history and in the memory of social struggles. Although their rebellion was suppressed, it highlighted latent tensions within medieval societies and served as a precedent for future popular movements. Fear of new uprisings led the Florentine elite to consolidate more authoritarian regimes and further restrict political participation by lower classes. The impact of the revolt did not limit itself to Florence. In other Italian city-states such as Siena and Milan, the working classes observed the Florentine events closely. As Rubinstein (1989, p. 187) explains, "the fear of new insurrections led Italian cities to consolidate more authoritarian regimes and further restrict political participation."
