The Ciompi Revolt of 1378

The Ciompi Revolt of 1378 was one of the most remarkable social and political upheavals in medieval Florence. At the height of the city’s powerful textile economy, workers with little formal political representation challenged the guild-dominated government and, for a brief period, gained a voice within the Florentine Republic.

The revolt reveals a side of Florence that can easily disappear behind Renaissance masterpieces and magnificent palaces. Long before the Medici transformed the city’s political landscape, Florence was a commercial republic shaped by merchants, guilds, artisans and thousands of labourers whose work created much of its wealth.

This article forms part of our History of Florence – Complete Guide and develops one of the central social tensions explored in The Medieval Republic of Florence – Guilds, Power and Civic Life.

Who Were the Ciompi?

The term Ciompi is generally associated with lower-status workers employed in Florence’s enormous wool industry. Many performed difficult stages of cloth production for businesses controlled by members of the powerful Arte della Lana, the Wool Guild.

These labourers were essential to the Florentine economy. However, economic importance did not automatically bring political influence.

The republic organised much of civic participation through recognised guilds. Workers who lacked membership in one of them therefore had very limited opportunities to participate formally in government.

This contradiction lay at the heart of the crisis. Florence depended on the labour of thousands of people who helped create its prosperity while excluding many of them from the institutions through which political power was exercised.

Florence and the Wealth of Wool

To understand the Ciompi Revolt of 1378, it is necessary to understand the importance of cloth. Medieval Florence was one of Europe’s major centres for the production and finishing of high-quality woollen textiles.

Florentine merchants obtained raw materials through international trading networks. Wool then passed through numerous specialised stages before finished cloth could be sold across Europe and the Mediterranean.

The industry generated enormous wealth. Successful merchants could build family fortunes, participate in government and invest in banking, property, churches and charitable institutions.

Yet this prosperity depended on a large workforce whose economic security could be precarious. Considerable differences in wealth and political status therefore existed within the same production system.

The Guild Republic

Florence was not governed by a hereditary duke or king in 1378. It was a republic whose political institutions were closely connected with the city’s guild system.

The most influential guilds represented major commercial and professional interests. Membership could provide not only economic protection and professional identity but also access to public office.

At the centre of government stood the Signoria, whose members included the Priori and the Gonfaloniere di Giustizia. Although the system was designed to prevent permanent domination by one person, political participation remained far from universal.

Workers without recognised guild representation stood largely outside this formal constitutional framework.

Why Did the Ciompi Revolt?

The uprising did not result from one grievance. Economic insecurity, taxation, political exclusion and resentment towards established guild elites all contributed to the tensions that erupted in 1378.

Florence had also experienced decades of instability. The fourteenth century brought warfare, financial crises, the Black Death of 1348 and continuing political struggles among powerful groups.

These pressures affected different sections of society in different ways. Workers without guild representation possessed few formal mechanisms through which grievances could be addressed.

Their demands therefore concerned not only wages or working conditions but also recognition and political participation.

The revolt ultimately became a challenge to the question of who had the right to belong politically to the Florentine Republic.

The Tumulto dei Ciompi Begins

During the summer of 1378, political tensions in Florence intensified. What began within a broader struggle among established political factions widened as workers and other excluded groups entered the conflict.

In July, crowds gathered, buildings associated with political opponents were attacked and the existing order came under extraordinary pressure.

The centre of Florence became the centre of the uprising. Piazza della Signoria and the government palace – today’s Palazzo Vecchio – were not distant symbols of authority. They were the places where political power was physically exercised.

For a brief moment, people normally excluded from formal government forced themselves into the heart of the republic.

Michele di Lando

The figure most closely associated with the revolt is Michele di Lando. Contemporary and later accounts identify him as a worker connected with the wool industry, often described as a carder.

In July 1378, Michele di Lando became Gonfaloniere di Giustizia, one of the highest offices in the Florentine Republic.

His elevation was extraordinary. A man associated with the labouring population had suddenly reached the centre of civic government.

Yet his position was difficult from the beginning. He had to negotiate between demands from below and the need to restore order in a city whose political institutions and economy were under enormous strain.

As the revolt developed, Michele increasingly came into conflict with more radical participants who expected further political and economic change.

The Creation of New Guilds

One of the most important achievements of the revolt was the recognition of new guild organisations representing groups previously excluded from the established political system.

Three new guilds were created. One represented the Ciompi themselves, while the others represented lesser artisans and tradesmen who had also lacked adequate political representation.

This mattered because guild recognition opened the possibility of participation in government.

The uprising therefore briefly changed the constitutional structure of Florence rather than simply replacing one group of officeholders with another.

For a short period, the boundaries of Florentine political citizenship became wider.

A Government Under Pressure

The success of the uprising immediately created new problems. The coalition responsible for political change contained groups with different interests and expectations.

Some participants wanted political recognition. Others sought economic relief, changes in taxation or greater protection from employers.

More radical workers demanded further concessions after the first reforms had already been achieved. Meanwhile, merchants and established guild members feared losing political authority and disrupting the economy on which their own prosperity depended.

Michele di Lando increasingly positioned himself between these competing forces.

The alliance that had made the uprising successful therefore began to fracture.

The War of the Eight Saints and Florence’s Political Crisis

The broader background to 1378 included Florence’s recent conflict with Pope Gregory XI, known as the War of the Eight Saints.

The war placed substantial financial and political pressure on the republic. Taxation required to finance conflict added to existing tensions, while struggles among Florence’s ruling groups weakened consensus within government.

The Ciompi Revolt therefore did not erupt in an otherwise stable city. It occurred during a period when diplomatic, economic and political pressures had already placed considerable strain on the republic.

The Radicalisation of the Revolt

By August 1378, some Ciompi believed the new political arrangements did not go far enough. A more radical organisation emerged and attempted to impose additional demands on the government.

This development placed Michele di Lando directly against sections of the movement that had helped bring him to power.

The conflict culminated around Piazza della Signoria. Forces supporting the government confronted the more radical insurgents, who were defeated.

The extraordinary political experiment created during the uprising began to unravel almost as quickly as it had emerged.

Why Did the Ciompi Revolt Fail?

The revolt faced several fundamental problems. The groups involved did not form one unified social or political movement, and their aims differed considerably.

Moreover, Florence’s established economic elites retained substantial institutional influence and financial resources.

Disruption of textile production also threatened the livelihood of the workers themselves. Once moderate artisans and sections of the guild population withdrew their support from more radical demands, the Ciompi became increasingly isolated.

Political representation won during the uprising was gradually dismantled. By 1382, a substantially more restrictive oligarchic political order had been firmly restored.

Was the Ciompi Revolt a Workers’ Revolution?

The uprising is sometimes described as one of the earliest workers’ revolts in European history. The comparison is understandable, but it requires caution.

Concepts such as an industrial working class, modern trade unions and socialist politics belong to much later periods. Fourteenth-century Florence operated according to very different economic and political structures.

Nevertheless, the revolt was exceptional because economically subordinate workers collectively demanded recognition within a political system from which many had been excluded.

For this reason, historians of labour, republican government and popular politics continue to study the events of 1378.

What Happened After the Revolt?

The immediate political gains of the Ciompi proved short-lived. Their guild was abolished, while the broader expansion of participation was gradually reversed.

Florence subsequently moved towards government dominated by a narrower group of wealthy and influential citizens.

The political order that emerged after the crisis helped shape the republic during the decades preceding the rise of Medici influence.

Yet the revolt could not simply be erased from Florentine memory. It had demonstrated that groups normally excluded from government could organise collectively and temporarily transform the institutions of one of Europe’s wealthiest cities.

The Ciompi, the Black Death and Fourteenth-Century Florence

The revolt becomes easier to understand when placed within the broader crises of the fourteenth century. The Black Death had devastated Florence only thirty years earlier, while financial collapses and warfare repeatedly disrupted economic life.

The great banking houses of the Bardi and Peruzzi had already failed during the century, demonstrating how vulnerable Florence could be despite its commercial sophistication.

Population loss, shifting labour conditions and political tension therefore formed part of the world in which the Ciompi uprising occurred.

The revolt was not an isolated explosion. It belonged to a century in which Florence repeatedly had to rebuild political and economic stability after severe shocks.

From the Ciompi to the Medici

The uprising occurred more than half a century before Cosimo de’ Medici established the political dominance that made his family synonymous with Renaissance Florence.

Nevertheless, the events of 1378 formed part of the political world from which Medici power eventually emerged.

Florence remained a republic characterised by complicated alliances among guilds, wealthy families and social groups. The memory of instability encouraged later elites to value control and consensus, even while republican institutions formally survived.

Understanding the Ciompi therefore helps explain why fifteenth-century Florence could simultaneously celebrate republican liberty and tolerate the growing informal influence of powerful families.

Our guide to The Medici Family: The Dynasty That Shaped Florence follows the later development of this political world.

The Ciompi and Florence’s Great Families

The uprising also reveals the contrast between ordinary workers and the powerful family networks that dominated much of Florentine politics.

Dynasties such as the Bardi, Peruzzi, Albizzi, Strozzi and later the Medici could combine commercial wealth with marriage alliances, property and access to political office.

Workers without recognised guild status possessed none of these advantages.

Our Most Famous Florentine Families in History guide provides the opposite side of this social landscape and helps explain just how unequal access to political influence could be.

Where to Find the Story of the Ciompi in Florence

Unlike the Medici, the Ciompi did not leave behind grand family palaces or monumental chapels. Their historical presence is therefore harder to see.

Yet the landscape of the uprising survives through the streets and institutions of central Florence.

Piazza della Signoria

The great civic square stood at the heart of political life and became a crucial setting during the uprising. Standing here today makes it easier to understand how directly public protest confronted the government.

Palazzo Vecchio

Known in the fourteenth century as the Palazzo della Signoria, the building housed the institutions the Ciompi sought to enter and influence. Michele di Lando exercised his extraordinary political authority within this civic world.

Via dei Calzaiuoli and the Medieval Centre

The streets around Piazza della Signoria connected government with commercial and artisan districts. Although their appearance has changed substantially, they still reveal how compact the political and economic geography of medieval Florence was.

Orsanmichele

Few buildings demonstrate the relationship between commerce, religion and guild identity as clearly as Orsanmichele. Its guild niches make it an ideal place to understand how deeply economic organisations were embedded in civic life.

Why the Ciompi Revolt of 1378 Matters

The Ciompi Revolt of 1378 matters because it exposes the tensions hidden beneath the prosperity of medieval Florence. The city’s celebrated textile economy created extraordinary wealth, but political influence was distributed very unevenly among the people who participated in it.

For a brief period, workers normally outside the recognised guild system entered the government and attempted to redefine political participation.

Their success lasted only a short time, yet the event challenged assumptions about who possessed the right to exercise civic power.

The revolt also reminds us that Florence’s history was not created only by famous bankers, merchants, artists and ruling families. Anonymous men and women who washed, combed, carded, spun, dyed and finished cloth were equally essential to the economy that made the city powerful.

Seen from this perspective, the Ciompi Revolt is not a marginal episode. It belongs to the larger story of how wealth, labour and political power interacted in medieval Florence.

Frequently Asked Questions About the Ciompi Revolt

What was the Ciompi Revolt of 1378?

The Ciompi Revolt was a political and social uprising in Florence in which workers connected particularly with the wool industry, together with other excluded groups, challenged the established guild government and briefly gained formal political representation.

Who were the Ciompi?

The Ciompi were lower-status labourers associated mainly with the Florentine wool industry. Although their work was essential to the textile economy, they lacked their own recognised guild and therefore had little formal political representation.

Why did the Ciompi revolt?

The uprising resulted from a combination of political exclusion, economic insecurity, taxation and resentment towards the established guild elite.

Who was Michele di Lando?

Michele di Lando was a worker associated with the wool industry who emerged as a leading figure during the uprising. In July 1378, he became Gonfaloniere di Giustizia, one of the highest offices in the Florentine Republic.

Did the Ciompi take control of Florence?

For a brief period, the uprising transformed the city’s government and gave previously excluded groups formal representation. However, the movement quickly divided and more radical participants were defeated in August 1378.

How long did the Ciompi Revolt last?

The decisive phase took place during the summer of 1378. Although some political changes survived temporarily, the most radical period lasted only weeks.

What happened to the new Ciompi guild?

The guild created to represent the Ciompi was soon abolished as the political gains of the uprising were reversed. By 1382, Florence had returned to a substantially more restrictive political order.

Was the Ciompi Revolt the first workers’ revolution?

It is sometimes described as an early workers’ revolt, but modern concepts of class and industrial labour should be applied cautiously. Its importance lies in the collective political mobilisation of workers excluded from Florence’s guild-based political system.

Where did the Ciompi Revolt take place?

Much of the political confrontation centred on Piazza della Signoria and the Palazzo della Signoria, now Palazzo Vecchio. The wider movement was rooted in the workshops, streets and textile economy of medieval Florence.
