Giuseppe Mazzini and his political thought is not well known outside of Italy. Here is an overview of his historical role that led to Italy’s unification, as well as a breakdown of his political, religious and social thought.
Giuseppe Mazzini (1805–1872) was an Italian revolutionary, political thinker, and one of the founding fathers of modern Italy.
Outside of Italy, Mazzini is not very well known, and his political thought has been mostly confined to academia or history books. However, he lived one of the most politically exciting lives during the turbulent years of the 1848 democratic revolutions and contributed significantly to the political debates that would shape both democratic movements in Europe and the international world order.
Here is a compiled overview of Giuseppe Mazzini’s life, thought, and ideas, as well as details about his major works and what books to read in order to learn more about him.

Giuseppe Mazzini’s Life and Historical Role
Giuseppe Mazzini’s political career spanned over four decades during which he was an active participant in Italy’s unification movement as well as in wider intellectual life. Here’s an overview of his life and how he contributed to Italy’s founding.
What is Giuseppe Mazzini known for?
Giuseppe Mazzini is known for his pivotal role in the Italian unification movement, Il Risorgimento. He is celebrated for orchestrating multiple insurrections against the monarchical and imperial rule of the Italian states. In Italy, he is regarded as one of the four founding fathers of the nation, alongside Giuseppe Garibaldi, Francesco Crispi, and Count Cavour.
What did Giuseppe Mazzini do?
Mazzini’s life was one of constant political action across several decades and in several countries. In 1831 from his exile in Marseilles, he founded Young Italy, a mass political movement with a clear program for a unified, republican Italy. In 1834, he extended that vision internationally with the founding of Young Europe, an alliance of democratic movements from Italy, Germany, Poland, and Switzerland aimed ultimately at a federated, democratic United States of Europe.
Throughout the 1830s and 1840s, he organized a series of insurrections against the Italian monarchies—all of which failed, but still kept the cause alive and the pressure on. In 1849, he reached his political peak as a Triumvir of the Roman Republic, demonstrating what a Mazzinian government could look like in practice: guaranteeing civil liberties and abolishing the death penalty.
In London, he founded several revolutionary associations, opened a school for Italian refugee children, contributed to numerous political journals, engaged directly with figures like John Stuart Mill and Thomas Carlyle, and developed the philosophical writings that would outlast all of his revolutionary activity.
Why was Giuseppe Mazzini exiled?
Mazzini was exiled from Italy due to his revolutionary activities against the Austrian imperial rule. He was arrested by the Piedmontese authorities and, after he was released due to a lack of evidence, he was given the choice either to accept internment in a small village in Piedmont or permanent exile, which he chose and went to Marseilles.
From Marseilles he was expelled after the French authorities came under pressure from the surrounding monarchies. He moved between Swiss cantons for years, constantly hunted by agents of Austria, France, and Piedmont, before eventually settling in London, which offered a relatively greater tolerance for political refugees. Even there he was not entirely safe: in 1844 the British government was caught secretly opening his correspondence and sharing its contents with the Austrian ambassador, in what became known as the Opening Letters Affair, a public scandal that paradoxically boosted his standing in British intellectual circles.
Mazzini spent the rest of his life moving between London, Switzerland, and occasional clandestine visits to Italy, and died in 1872 under a false name in Pisa, technically still a fugitive in the country he had helped to create.
What was the secret society founded by Mazzini?
The most significant society that Mazzini founded was Young Italy (Giovine Italia). Though he was a member of secret society the Carbonari, he left it earlier on because he believed the culture of total secrecy was an obstacle to building the popular mass movement that genuine revolution required. To this effect, Young Italy was to inspire a popular revolution and was in a sense Italy’s first political party: it had a membership structure, a clear ideological program, and a newspaper, and it recruited thousands of members across Italy and the Italian diaspora in Europe.
What was the relationship between Giuseppe Garibaldi and Mazzini?
Mazzini and Garibaldi, both instrumental in shaping modern Italy, collaborated to bring their vision to life. Garibaldi joined Young Italy and participated in the Savoy insurrection in 1834. However, their alliance crumbled due to profound ideological and tactical differences, particularly Garibaldi’s willingness to ally with the Piedmontese monarchy, which Mazzini considered a betrayal of their strict republican and unitarian principles.
Conversely, Garibaldi disliked Mazzini’s intellectual dogmatism, labeling him the “great doctrinaire” and criticizing him as a dictatorial egoist lacking practical military acumen. He accused Mazzini of trying to control events from afar. While Garibaldi occasionally acknowledged Mazzini’s contributions, famously toasting him in London in 1864 as his “friend and master” who had preserved the sacred flame of patriotism, their animosity ultimately prevailed. Garibaldi unjustly blamed Mazzini’s interference for military setbacks like the defeat at Mentana and flatly rejected Mazzini’s late-life attempts at reconciliation.
Where did Giuseppe Mazzini live in London?
Mazzini lived in a number of addresses in the Bloomsbury and areas of central London. He is associated with addresses on Devonshire Street (now Boswell Street) and later on North Gower Street, near Euston station. A blue plaque at 183 North Gower Street marks one of the homes where he lived. During his first London period he lodged near Thomas Carlyle in Chelsea, and he moved frequently throughout his years in the city. His time in London was intellectually rich despite being materially difficult: he developed close friendships with Carlyle and John Stuart Mill, contributed to numerous journals and newspapers, founded a school for Italian refugee children, and developed the philosophical writings that would define his legacy.

The 1844 Opening Letters Affair was a significant British political scandal that unfolded when Mazzini discovered that his private mail was being covertly intercepted, read, and resealed by the Post Office. He discovered it by observing altered postmarks and strategically placing poppy seeds and hairs in his letters as traps. The interception of Mazzini’s mail had been authorized by Home Secretary Sir James Graham to appease the Austrian government, resulting in the sharing of intelligence with foreign powers. Tragically, this led to the ambush and execution of the Bandiera brothers in southern Italy.
Mazzini exposed this constitutional violation by petitioning Parliament through MP Thomas Duncombe. The scandal sparked a massive public outcry and intense parliamentary debates, questioning the government’s role as an informant for despotic regimes. Prominent figures like Thomas Carlyle publicly defended Mazzini and condemned the government’s actions.
Despite the government’s attempts to justify the surveillance and Foreign Secretary Lord Aberdeen’s subsequent lie about leaking the intelligence, the scandal deeply embarrassed the ministers involved. Consequently, it dramatically increased British public sympathy for Mazzini and the Italian national cause.
What was the Roman Republic in 1849?
The Roman Republic of 1849, a brief democratic state established on February 9, 1849, emerged after Pope Pius IX fled. This Republic, founded through universal suffrage, abolished the Pope’s temporal authority, initiating a significant liberal experiment. It granted unprecedented civil liberties, including religious freedom, a free press, and equal citizenship before the law.
Giuseppe Mazzini arrived in Rome in March and was swiftly appointed to the governing Triumvirate alongside Aurelio Saffi and Carlo Armellini. He became the de facto political leader of the Republic. During his tenure as Triumvir, Mazzini demonstrated remarkable administrative skills, steering the state with a moderate, secular vision. He suppressed Jacobin-style anticlerical violence while advocating for social reforms.
However, when a French military intervention crushed the Republic and reinstated the Pope, Mazzini inspired a heroic military defense. Despite the city’s resistance, which ultimately collapsed in July 1849, he resigned his post and returned to exile. Rather than surrendering his republican principles by signing the capitulation, he chose to uphold his ideals.
Where is Mazzini buried?
Mazzini is buried at the Cimitero Monumentale di Staglieno in Genoa, one of the most celebrated monumental cemeteries in Europe. He died on March 10, 1872, in Pisa, under a false name, and his body was carried back to his native Genoa, where a funeral procession attended by an estimated 100,000 people mourned what many called the passing of the Soul of Italy. His tomb at Staglieno can be visited free of charge.

Mazzini's legacy is both significant and underappreciated, particularly outside Italy. Within Italy, he is recognized as one of the four founding fathers of the unified nation alongside Garibaldi, Cavour, and King Victor Emmanuel II. His portrait appears on the Italian one-euro coin, and streets, piazzas, and galleries across the country bear his name.
Internationally, his influence was enormous but often unacknowledged. His doctrine of national self-determination directly shaped the thinking of Woodrow Wilson, whose Fourteen Points carried clear Mazzinian echoes, as well as Sun Yat-sen, the founder of the Chinese Republic, Mahatma Gandhi, Jawaharlal Nehru, David Ben-Gurion, and José Rizal of the Philippines. The liberal international order that took shape after the First World War was, in important respects, a practical realization of ideas Mazzini had set out seventy years earlier.
Giuseppe Mazzini’s Beliefs and Political Thought
Mazzini had deeply idiosyncratic political and religious beliefs, but they were all aimed principally at his humanitarian goals and his desire to see Italy emancipated from foreign tyranny. Here is an overview of his beliefs as well as some insight into his ideas.
What were Mazzini's key beliefs?
Mazzini’s beliefs were founded on the principles of a form of patriotic democratic republicanism. His key political beliefs were the following:
Dio e Popolo: “God and the People” as the relationship a people has with God—as the giver of divine law—and the people—its executor.
Nation as Bridge: The nation for Mazzini was to act as a bridge between the individual and humanity in order to provide a tangible and practical path for the former to achieve the latter.
Humanity as Goal: Mazzini held that the goal was the unity of all humanity through working together as nations.
Duties before Rights: Duties were vital for giving rights direction and for providing individuals with equality within the nation and humanity.
Proto-Social Democracy: Mazzini believed in an active state in the economy that guaranteed property but also provided free national education and opportunities.
Democratic internationalism: He was strongly internationalist, seeing the liberation of all nationalities as the clear path for human emancipation. He was universalist in his democratic principle.
Was Mazzini opposed to individual rights?
Mazzini was not opposed to individual rights or civil liberties. In fact, he believed they were necessary for an individual to fulfill their duties. For Mazzini, individual rights alone were not sufficient as they provided no direction, and he saw that rights were not useful for those who had no means of exercising them. For this reason, Mazzini believed duties were essential for the individual to use their liberty for the good of humanity.
Why did Mazzini want to unify Italy?
For Mazzini, Italian unification was both a practical political necessity and a moral imperative rooted in his broader philosophy. Practically, the Italy of his time was divided into numerous separate states, most under the control or influence of Austria, France, or the Papacy, leaving Italians politically oppressed and economically fragmented. That alone was sufficient injustice to demand action.
However, Mazzini's motivations went deeper than national liberation. Drawing on his concept of nationality, he believed that each nation had a distinct mission to contribute to the progress of humanity as a whole. Italy, as the home of Roman civilization and the Renaissance, had a particular duty to lead by example. A free, unified, republican Italy was not an end in itself but the necessary precondition for Italy to play its rightful part in the universal advance of human freedom.
Unification without a republic, in his view, was not true unification at all, which is exactly why the monarchical outcome of 1861 left him profoundly disillusioned.
How did Giuseppe Mazzini help unify Italy?
Mazzini's contribution to Italian unification was primarily ideological and organizational rather than military (though he did write pamphlets on how guerrilla war should be conducted). By founding Young Italy and giving the Risorgimento a coherent republican program, he transformed what had been a loose patriotic sentiment into a genuine mass movement.
While in exile in Marseilles, he met Garibaldi, who would go on to lead the military campaigns that made unification physically possible. He kept the insurrectionary pressure alive through decades of uprisings and agitation that forced the hand of more conservative figures like Count Cavour. Through the Roman Republic of 1849, however briefly, he showed what a democratic Italy could look like in practice.
What was Mazzini's ideology?
Mazzini’s ideology does not fit well into our modern definitions. Mazzini rejected both full-on liberalism as well as socialism and communism, while also being a strong opponent of absolute monarchy. Mazzini had idiosyncratic political beliefs that were far ahead of his time, combining aspects from both sides of the political spectrum. He was one of the earliest to advocate a mixed approach to economics, aligning him with the ideas of social democracy that came after him. However, the best description of Mazzini’s ideology for the time is patriotic democratic republicanism.
What was Mazzini's view on nationalism?
Mazzini’s view on nationalism was critical. While he is frequently described as a romantic nationalist, the truth is that he was a sharp critic of nationalism as it was commonly practiced in his time (and also he was underwhelmed by romanticism). He used the word "nationalist" to describe what he called the "selfish Nationalism of absolute powers"—the chauvinistic ideology deployed by monarchs and emperors to justify conquest, imperialism, and the suppression of other peoples. This kind of nationalism, which treated the nation as an end in itself, he regarded as morally and politically bankrupt.
His own position was built on a fundamentally different premise. He believed that the nation was a means toward humanity, not an end. Each people had the right to self-determination not because their nation was superior to others, but because self-governing democratic republics were the only durable foundation for international peace and human progress. He was just as committed to the freedom of the Poles and the Hungarians as he was to the freedom of Italians, and he built international organizations to give that commitment practical form.
So, was Giuseppe Mazzini an Italian nationalist?
As per the answer above, Mazzini would have strongly contested the nationalist label. He rejected the nationalist label throughout his life, and his political actions consistently reflected that rejection. The organizations he built, Young Europe, the European Central Democratic Committee, were explicitly internationalist.
That said, there is an honest complexity here. Mazzini was passionately devoted to Italy, spent his life fighting for its freedom, and believed Italians had a special mission to contribute to the world. In that sense, a certain kind of patriotism was central to everything he did. The distinction he drew (and insisted on) was between patriotism as a form of love and service, and nationalism as a form of domination and exclusion.
By modern definitions, he was closer to a patriot democratic republican and democratic internationalist than a nationalist in any conventional sense. Whether that distinction holds up under scrutiny is itself one of the more interesting questions his thought poses.
What kind of government did Mazzini want?
Mazzini wanted a democratic republic founded on universal suffrage, the separation of church and state, freedom of the press and of religious conscience, and strong local self-government as a check on centralized power. He regarded the republic and democracy as virtually synonymous, summarizing the democratic creed as "the progress of all through all, under the leading of the best and wisest."
He was uncompromising in his opposition to monarchy, which he considered incompatible with genuine democracy. But he was equally opposed to the concentration of power at the center of any republican government. He advocated for local self-government and civic participation as the essential counterweights to state authority, though he was an opponent of federalism for Italy, preferring national unity with local autonomy built in. His appreciation of localism was shaped by his experience in England.
Crucially, Mazzini insisted that the republican state had to be built from below, through a Constituent Assembly elected by popular vote, and not imposed from above by military conquest or royal decree. This is precisely why he refused to accept the outcome of Italian unification in 1861, and why he died in 1872 under a false name, technically still an outlaw in the country he had spent his life trying to create.
What was Mazzini’s views on Communism?
Mazzini was fiercely critical of Communism and had a particular disdain for Marx’s emphasis on historical materialism and class warfare. He believed that communism's fatal flaw was its foundation in materialism, which focused exclusively on satisfying physical wants while completely ignoring the moral, spiritual, and educational development of humanity.
Mazzini warned that Communism would inevitably result in absolute tyranny. He observed that a system where the government acts as the sole proprietor, possessor, and distributor of all capital, land, and labor is inherently despotic. To enforce absolute equality in production and consumption or to distribute goods according to dictated “wants,” society would require an arbitrary hierarchy of leaders. Seduced by the immense power concentrated in their hands, these new chiefs would quickly form a dictatorial "caste of masters" ruling over a caste of laborers. In this sense, he was essentially an early critic of the totalitarian tendency of large bureaucracies.
Above all, Mazzini was opposed to class struggle, seeing it as sectarian and undermining the patriotic unity of the nation, replacing the selfishness of the ruling classes with a new form of class-based egoism. Instead, he emphasized a more humanistic class collaboration.
Did Mazzini’s political thought influence Fascism?
Mazzini’s political thought was appropriated by the Italian Fascists—particularly Giovanni Gentile—who used his thoughts on national mission as a way to justify Italian imperialism and aggression. In many instances, Mazzini’s thought was stretched beyond their democratic republicanism and twisted into something that it categorically wasn’t.
However, Mazzini’s intellectual weaknesses in his approaches to duties over rights, thought and action, and his religious perspective toward politics, made it much more susceptible to totalitarian interpretations to appropriate. These were the parts that Mussolini would use to create Fascism.
Mazzini’s thought was also fundamental in inspiring many antifascist movements. For example, the antifascist organization led by Carlo and Nello Rosselli, Giustizia e Libertà, had Mazzinian roots. In reality, given Mazzini’s fierce opposition to monarchical despotism and tyranny, he would have likely vehemently opposed Fascism and the twisting of his views.
Was Mazzini a Christian? What were his religious beliefs?
Mazzini’s relationship with Christianity was complex and not altogether clear. His mother, Maria Drago, was a passionate Jansenist and instilled the young Mazzini with a strict moral code. Mazzini was a strong believer in God and held his political thought as a practical application of religious principles.
However, from his time at university to the end of his career, Mazzini was a strong anti-clerical and opposed the Papacy for its tyranny. He believed that between God and the people, there ought to be no intermediary and he was strongly against any kind of tyrannical theocracy. That being said, some have described Mazzini’s political beliefs as a political religion and have even gone as far as to suggest it is a form of “popular theocracy”.
Mazzini was deeply admiring of Jesus and believed him to have been a significant teacher of morality; however, he expressed his non-Christianity multiple times throughout his life and desired a “universal catholicism”, which could also be described as a sort of religious humanism.
Was Giuseppe Mazzini a Freemason?
Giuseppe Mazzini was not a Freemason, however the truth is also more nuanced. Mazzini was certainly associated with the secret association Carbonari who were mostly Freemasons, and Mazzini throughout many of the organizations he set up utilized symbols and secret passwords as part of the structure (for example with Young Europe).
This claim is owed to the forged Albert Pike letters. The American Confederate general Albert Pike is frequently cited in conspiracy literature as having exchanged letters with Mazzini about a shared Masonic or Illuminati project for world domination. These letters have been comprehensively debunked by historians as fabrications and anachronistic references to Fascism and Communism.
Also, his political philosophy, grounded in a deeply personal and unorthodox religious belief, was in many respects at odds with the rationalist and materialist tendencies more commonly associated with Masonic thought.
What Books Did Mazzini write?
Mazzini was a prolific writer throughout his life, producing pamphlets, political essays, and correspondence in enormous quantities. His major works include:
Major Works
Manifesto of Young Italy (1831): The founding document of his political movement, written during his first exile in Marseille, setting out his vision for a popular republican revolution that would liberate the Italian Peninsula from foreign domination and unite it under a republican government.
Thoughts on Democracy in Europe (1846–47): A series of essays published in the English People's Journal, critiquing liberalism, socialism, and communism, in which Mazzini rejected the materialism of French Fourierism and German communism, insisting that democracy must be an ethical and educational movement aimed at making man better rather than a mere pursuit of rights or material utility.
Note autobiografiche (1861–65): Autobiographical notes interspersed throughout the first eight volumes of his collected works, in which Mazzini provided a comprehensive history of the Italian political movement over the preceding thirty years, contextualising his past writings and explaining the development of his republican and unitarian ideals.
On the Duties of Man (Dei Doveri dell'Uomo, 1860): His most famous and enduring work, addressed to Italian workers, arguing that individual rights are insufficient without a corresponding sense of duty to family, country, and humanity, rejecting both the class struggle and socialism, and first published in instalments in his paper Apostolato Popolare in 1841–42 as well as in Pensiero ed Azione before being completed as a book in 1860.
Newspapers & Journals
Giovine Italia: A review and series of political pamphlets established in Marseille in 1832 as the official organ of the Young Italy association, openly preaching republican and unitarian beliefs to incite insurrection in Italy, and secretly smuggled into the country to evade censorship.
Jeune Suisse: A bilingual French and German journal founded by Mazzini in Bienne, Switzerland, in 1835, intended to foster a Swiss national identity and connect Swiss patriots with the broader Young Europe movement, before conservative European powers pressured the Swiss Diet to suppress it and banish Mazzini.
Apostolato Popolare: Published between 1840 and 1843 in London and Paris as the organ of the Union of Italian Workers, through which Mazzini aimed to educate the poorer classes, demand social reform, and counter the influence of foreign communist programmes he feared were distracting Italian exiles from the national cause.
Pensiero ed Azione: Founded in London in 1858 and later printed in Lugano and Genoa until 1860, its title—Thought and Action—reflecting Mazzini's core philosophy unifying theory and practice, used to promote European nationalities and Italian unification while opposing the diplomatic manoeuvres of Cavour and Napoleon III.
Compiled Works & Letters
Scritti Editi ed Inediti: The comprehensive collection of Mazzini's literary and political works, personally directed by him from the first Milan edition of 1861, gathering his pamphlets, journal articles, and translations bound together by his own autobiographical notes, and eventually expanded into a monumental National Edition of approximately 100 volumes.
Life and Writings of Giuseppe Mazzini: A six-volume English edition published in London in 1870, translated and edited by his devoted supporter Emilie Ashurst Venturi, making the bulk of his collected Italian works accessible to the English-speaking public for the first time.
Letters to an English Family: A three-volume compilation edited by E. F. Richards (1920–22), containing Mazzini's extensive personal correspondence with the Ashurst family, who provided him with a second homeland and vital moral and financial support throughout his long exile in England.
