Victor-Marie Hugo (26 February 1802 – 22 May 1885) was a French poet, playwright, novelist, essayist, visual artist, statesman, human rights activist and exponent of the Romantic movement in France.

In France, Hugo's literary fame comes first from his poetry but also rests upon his novels and his dramatic achievements. Among many volumes of poetry, Les Contemplations and La Légende des siècles stand particularly high in critical esteem, and Hugo is sometimes identified as the greatest French poet. Outside France, his best-known works are the novels Les Misérables and Notre-Dame de Paris. Though a committed conservative royalist when he was young, Hugo grew more liberal as the decades passed; he became a passionate supporter of republicanism, and his work touches upon most of the political and social issues and artistic trends of his time. He is buried in the Panthéon.

Victor Hugo was the third and last son of Joseph Léopold Sigisbert Hugo (1773–1828) and Sophie Trébuchet (1772-1821); his brothers were Abel Joseph Hugo (1798–1855) and Eugène Hugo (1800–1837). He was born in 1802 in Besançon (in the region of Franche-Comté) and lived in France for the majority of his life. However, he was forced into exile during the reign of Napoleon III — he lived briefly in Brussels during 1851; in Jersey from 1852 to 1855; and in Guernsey from 1855 to 1870 and again in 1872-1873. There was a general amnesty in 1859; after that, his exile was by choice.

Hugo's early childhood was marked by great events. The decades prior to his birth saw the overthrow of the Bourbon Dynasty in the French Revolution, the rise and fall of the First Republic, and the rise of the First French Empire and dictatorship under Napoléon Bonaparte. Napoléon was proclaimed Emperor two years after Hugo's birth, and the Bourbon Monarchy was restored before his eighteenth birthday. The opposing political and religious views of Hugo's parents reflected the forces that would battle for supremacy in France throughout his life: Hugo's father was an officer who ranked very high in Napoleon's army. He was an atheist republican who considered Napoléon a hero; his mother was an extreme Catholic Royalist who is believed to have taken as her lover General Victor Lahorie, who was executed in 1812 for plotting against Napoléon. Since Hugo's father, Joseph, was an officer, they moved frequently and Hugo learned much from these travels. On his family's journey to Naples, he saw the vast Alpine passes and the snowy peaks, the magnificently blue Mediterranean, and Rome during its festivities. Though he was only nearly six at the time, he remembered the half-year-long trip vividly. They stayed in Naples for a few months and then headed back to Paris. Sophie followed her husband to posts in Italy (where Léopold served as a governor of a province near Naples) and Spain (where he took charge of three Spanish provinces). Weary of the constant moving required by military life, and at odds with her unfaithful husband, Sophie separated temporarily from Léopold in 1803 and settled in Paris. Thereafter she dominated Hugo's education and upbringing. As a result, Hugo's early work in poetry and fiction reflect a passionate devotion to both King and Faith. It was only later, during the events leading up to France's 1848 Revolution, that he would begin to rebel against his Catholic Royalist education and instead champion Republicanism and Free thought.

Young Victor fell in love and against his mother's wishes, became secretly engaged to his childhood friend Adèle Foucher (1803-1868). Unusually close to his mother, he felt free to marry Adèle (in 1822) only after his mother's death in 1821. They had their first child Léopold in 1823, but the boy died in infancy. Hugo's other children were Léopoldine (28 August 1824), Charles (4 November 1826), François-Victor (28 October 1828) and Adèle (24 August 1830). Hugo published his first novel the following year (Han d'Islande, 1823), and his second three years later (Bug-Jargal, 1826). Between 1829 and 1840 he would publish five more volumes of poetry (Les Orientales, 1829; Les Feuilles d'automne, 1831; Les Chants du crépuscule, 1835; Les Voix intérieures, 1837; and Les Rayons et les ombres, 1840), cementing his reputation as one of the greatest elegiac and lyric poets of his time. Victor Hugo was devastated when his oldest and favorite daughter, Léopoldine, died at age 19 in 1843, shortly after her marriage. She was drowned in the Seine at Villequier, pulled down by her heavy skirts, when a boat overturned. Her young husband died trying to save her. Victor Hugo was traveling with his mistress at the time in the south of France, and learned about Léopoldine's death from a newspaper as he sat in a cafe. He wrote many poems afterwards about his daughter's life and death. His most famous poem is probably Demain, dès l'aube, in which he describes visiting her grave.

Like many young writers of his generation, Hugo was profoundly influenced by François-René de Chateaubriand, the famous figure in the literary movement of Romanticism and France’s preëminent literary figure during the early 1800s. In his youth, Hugo resolved to be “Chateaubriand or nothing,” and his life would come to parallel that of his predecessor in many ways. Like Chateaubriand, Hugo would further the cause of Romanticism, become involved in politics as a champion of Republicanism, and be forced into exile due to his political stances. The precocious passion and eloquence of Hugo's early work brought success and fame at an early age. His first collection of poetry (Odes et poésies diverses) was published in 1822, when Hugo was only twenty years old, and earned him a royal pension from Louis XVIII. Though the poems were admired for their spontaneous fervor and fluency, it was the collection that followed four years later in 1826 (Odes et Ballades) that revealed Hugo to be a great poet, a natural master of lyric and creative song.

Victor Hugo's first mature work of fiction appeared in 1829, and reflected the acute social conscience that would infuse his later work. Le Dernier jour d'un condamné (The Last Day of a Condemned Man) would have a profound influence on later writers such as Albert Camus, Charles Dickens, and Fyodor Dostoevsky. Claude Gueux, a documentary short story about a real-life murderer who had been executed in France, appeared in 1834, and was later considered by Hugo himself to be a precursor to his great work on social injustice, Les Misérables. But Hugo’s first full-length novel would be the enormously successful Notre-Dame de Paris (The Hunchback of Notre Dame), which was published in 1831 and quickly translated into other languages across Europe.

Hugo turned away from social/political issues in his next novel, Les Travailleurs de la Mer (Toilers of the Sea), published in 1866. Nonetheless, the book was well received, perhaps due to the previous success of Les Misérables. Dedicated to the channel island of Guernsey where he spent 15 years of exile, Hugo’s depiction of Man’s battle with the sea and the horrible creatures lurking beneath its depths spawned an unusual fad in Paris: Squids. Hugo returned to political and social issues in his next novel, L'Homme Qui Rit (The Man Who Laughs), which was published in 1869 and painted a critical picture of the aristocracy. However, the novel was not as successful as his previous efforts, and Hugo himself began to comment on the growing distance between himself and literary contemporaries such as Flaubert and Émile Zola, whose realist and naturalist novels were now exceeding the popularity of his own work. His last novel, Quatre-vingt-treize (Ninety-Three), published in 1874, dealt with a subject that Hugo had previously avoided: the Reign of Terror during the French Revolution. 

After three unsuccessful attempts, Hugo was finally elected to the Académie française in 1841, solidifying his position in the world of French arts and letters. A group of French academiciens, particularly Etienne de Jouy was fighting against the "romantic evolution" and had managed to delay Victor Hugo's election. Thereafter he became increasingly involved in French politics. He was elevated to the peerage by King Louis-Philippe in 1841 and entered the Higher Chamber as a pair de France, where he spoke against the death penalty and social injustice, and in favour of freedom of the press and self-government for Poland. However, he was also becoming more supportive of the Republican form of government and, following the 1848 Revolution and the formation of the Second Republic, was elected to the Constitutional Assembly and the Legislative Assembly. When Louis Napoleon (Napoleon III) seized complete power in 1851, establishing an anti-parliamentary constitution, Hugo openly declared him a traitor to France. He relocated to Brussels, then Jersey, and finally settled with his family on the channel island of Guernsey at Hauteville House, where he would live in exile until 1870. While in exile, Hugo published his famous political pamphlets against Napoleon III, Napoléon le Petit and Histoire d'un crime. The pamphlets were banned in France, but nonetheless had a strong impact there. He also composed or published some of his best work during his period in Guernsey, including Les Misérables, and three widely praised collections of poetry (Les Châtiments, 1853; Les Contemplations, 1856; and La Légende des siècles, 1859). He convinced the government of Queen Victoria to spare the lives of six Irish people convicted of terrorist activities and his influence was credited in the removal of the death penalty from the constitutions of Geneva, Portugal and Colombia. He had also pleaded for Benito Juarez to spare the recently captured emperor Maximilian I of Mexico but to no avail.

Although Napoleon III granted an amnesty to all political exiles in 1859, Hugo declined, as it meant he would have to curtail his criticisms of the government. It was only after Napoleon III fell from power and the Third Republic was proclaimed that Hugo finally returned to his homeland in 1870, where he was promptly elected to the National Assembly and the Senate. He was in Paris during the siege by the Prussian army in 1870, famously eating animals given to him by the Paris zoo. As the siege continued, and food became ever more scarce, he wrote in his diary that he was reduced to "eating the unknown." When Hugo returned to Paris in 1870, the country hailed him as a national hero. Despite his popularity Hugo lost his bid for reelection to the National Assembly in 1872. Within a brief period, he suffered a mild stroke, his daughter Adèle’s internment in an insane asylum, and the death of his two sons. (Adèle's biography inspired the movie The Story of Adele H.) His wife Adèle had died in 1868. His faithful mistress, Juliette Drouet, died in 1883, only two years before his own death. Despite his personal loss, Hugo remained committed to the cause of political change. On 30 January 1876 Hugo was elected to the newly created Senate. The last phase of his political career is considered a failure. Hugo took on the role of a maverick and got little done in the Senate.

In February 1881 Hugo celebrated his 79th birthday. To honor the fact that he was entering his eightieth year, one of the greatest tributes to a living writer was held. The celebrations began on the 25th when Hugo was presented with a Sèvres vase, the traditional gift for sovereigns. On the 27th one of the largest parades in French history was held. Marchers stretched from Avenue d'Eylau, down the Champs-Élysées, and all the way to the center of Paris. The paraders marched for six hours to pass Hugo as he sat in the window at his house. Every inch and detail of the event was for Hugo; the official guides even wore cornflowers as an allusion to Cosette's song in Les Misérables.

Victor Hugo's death on 22 May 1885, at the age of 83, generated intense national mourning. He was not only revered as a towering figure in literature, he was a statesman who shaped the Third Republic and democracy in France. More than two million people joined his funeral procession in Paris from the Arc de Triomphe to the Panthéon, where he was buried. He shares a crypt within the Panthéon with Alexandre Dumas and Émile Zola. Most large French towns and cities have a street named for him. The avenue where he died, in Paris, now bears his name.
