Why Italians Emigrated: Famine, Wars, and Unification
Discover the historical causes of the great Italian emigration: rural poverty, Italy's unification, and wars that drove millions to leave the country.

Between 1876 and 1920, millions of Italians left their homeland in search of a better life on other continents, in one of the largest migratory movements in modern history. This exodus, known as the Great Emigration, had deep roots in rural poverty, the political transformations of Italy's unification, and the conflicts that marked the country in the 19th century. For millions of Brazilians of Italian descent today, understanding this historical context is essential not only to reconstruct their own genealogy, but also to understand the foundations of the Italian citizenship recognition process.
Italy Before Unification: A Mosaic of Kingdoms
Until 1861, Italy as a unified nation simply did not exist. The territory we know today as Italy was fragmented into a series of kingdoms, duchies, and territories controlled by foreign powers, such as the Austrian Empire, which dominated regions in the North like Lombardia and Veneto, and the Bourbon dynasty, which governed the Kingdom of the Two Sicilies in the South.
This political fragmentation generated profound economic and cultural differences between regions. The North, closer to European commercial centers, was beginning to develop incipient industrialization, especially in areas like Piemonte and Lombardia. The South, known as the Mezzogiorno, remained trapped in archaic agrarian structures, with large estates controlled by a few aristocratic families and a peasant population living in conditions of semi-slavery.
Up to that point, there was no unified national identity. People identified first with their town, their region, their dialect — often mutually incomprehensible between different parts of the territory. It was only through the Risorgimento process, led by figures such as Giuseppe Garibaldi, Camillo di Cavour, and Vittorio Emanuele II, that political unification began to take shape, culminating in the proclamation of the Kingdom of Italy in 1861.
Famine and Rural Poverty: The Engine of Emigration
While unification brought with it the promise of a modern state, the reality experienced by the rural population was quite different. Italy's agricultural economy, especially in the South, faced a structural crisis. Small landowners saw their lands become increasingly less productive, victims of outdated farming techniques, excessive fragmentation of properties through inheritance, and competition from imported agricultural products, mainly from the United States, which drove down grain prices in the European market.
The situation worsened even further with the phylloxera crisis, an insect that devastated Italian vineyards starting in the 1880s, destroying one of the main sources of income for many peasant families, especially in the regions of Veneto, Calabria, and Sicilia.
Add to this rural overpopulation: the available land simply was not enough to sustain the demographic growth of peasant families. In the Mezzogiorno, living conditions were particularly precarious, with epidemics, malnutrition, and alarming infant mortality rates. For millions of families, emigrating was not a choice made out of adventure, but a matter of survival.
Italian Unification and Its Social Consequences
The Risorgimento had promised a fairer and more prosperous country, but for much of the peasant population that promise never materialized. On the contrary: the newly unified state imposed a series of measures that worsened the lives of the poorest.
One of the most decisive factors was the significant increase in taxes, especially the tax on grain milling (the so-called tassa sul macinato), which directly affected the basic food supply of the poorest families. This disproportionate taxation sparked popular uprisings in several regions, but the central government maintained a fiscal policy aimed at financing the modernization of the North, further deepening regional inequality.
Another determining factor was the introduction of mandatory military service, which pulled young men away from agricultural work for years and exposed them to conflicts that had little to do with their local interests. For many families, emigrating was also a way to escape this obligation, especially among the young.
The result of these policies was a South that became increasingly impoverished and marginalized, while the North, favored by investments in infrastructure and industry, began to develop at a completely different pace. This regional disparity, incidentally, is a phenomenon that still marks the Italian economy today.
Wars and Political Instability
The conflicts that marked the unification process — such as the wars of independence against Austrian rule and the military campaigns led by Garibaldi — left a trail of economic destruction in various regions of the peninsula. Cities and rural areas that served as battlegrounds saw their productive structures compromised, further aggravating the already existing agricultural crisis.
Moreover, unification did not eliminate internal social tensions. Resistance movements, especially in the South, arose in response to the policies of the new central government, often violently suppressed by the forces of the newly formed Kingdom of Italy. This phenomenon, known as brigantaggio, generated even more instability and insecurity in rural areas.
Decades later, the effects of World War I would bring a new wave of economic hardship, further intensifying the migratory flows that had already been occurring since the late 19th century. The combination of wars, political instability, and economic crisis created a scenario in which emigrating seemed, for millions of Italians, the only viable way out.
Brazil as a Destination: Coffee and New Opportunities
While Italy was experiencing this crisis, Brazil was undergoing an economic transformation that would create a growing demand for labor. With the abolition of slavery in 1888, the large coffee plantation owners in southeastern Brazil, especially in São Paulo, urgently needed workers to replace enslaved labor in the fields.
The Brazilian government, in partnership with state governments, especially that of São Paulo, created subsidized immigration policies, offering free or reduced-cost passage for Italian families willing to work on coffee plantations. This policy particularly attracted families from Veneto, Lombardia, and Calabria, regions hit hard by the agricultural crisis.
The Italian immigrants on São Paulo's coffee plantations faced often harsh working conditions under the colonato system, but for many families it represented the possibility of accumulating resources and, eventually, acquiring their own land. Besides São Paulo, important Italian colonies formed in southern Brazil, especially in Rio Grande do Sul and Santa Catarina, where immigrants dedicated themselves mainly to family farming and viticulture, reproducing traditions brought from their regions of origin.
The Legacy of the Great Emigration for Descendants
The impact of this mass migration is still felt today. It is estimated that Brazil is home to one of the largest populations of Italian descendants outside Italy, distributed mainly across the states of São Paulo, Rio Grande do Sul, Santa Catarina, Espírito Santo, and Minas Gerais.
Many of these communities have preserved, over generations, traditions, religious festivals, cuisine, and even regional dialects that, in some cases, are no longer spoken in Italy itself. This cultural richness can be observed in various expressions that are part of Italian culture and traditions in Brazil, from popular festivals to regional Italian cuisine adapted to the Brazilian context.
Beyond its historical and cultural value, this heritage has a fundamental practical significance: it is precisely through the records of these immigrants who arrived in Brazil that descendants can, even today, prove their right to Italian citizenship through recognition of bloodline, known as jure sanguinis. Birth, marriage, and death certificates of these ancestors, often kept in parish or civil registry archives in Italy, are essential documents in this process.
For those wishing to begin this journey, the first step is usually detailed genealogical research, identifying the Italian ancestor who emigrated and gathering as much information as possible about their hometown, date of birth, and migratory path. This work can include everything from consulting family documents to carrying out a records search in Italy directly through Italian municipal and ecclesiastical archives.
Conclusion
The history of the Great Italian Emigration is, in essence, the story of millions of families who faced hunger, war, and inequality in search of a dignified life. Understanding this past is not just an exercise in historical memory, but also a way to honor the courageous journey of ancestors who crossed the Atlantic toward Brazil.
