Mikhail Alexandrovich Bakunin (bəˈkuːnɪn ; 30 May 1814 – 1 July 1876) was a Russian revolutionary anarchist. He is among the most influential figures of anarchism and a major figure in the revolutionary socialist, social anarchist, and collectivist anarchist traditions. Bakunin's prestige as a revolutionary also made him one of the most famous ideologues in Europe, gaining substantial influence among radicals throughout Russia and Europe.
Bakunin grew up in Pryamukhino, a family estate in Tver Governorate. From 1840, he studied in Moscow, then in Berlin hoping to enter academia. Later in Paris, he met Karl Marx and Pierre-Joseph Proudhon, who deeply influenced him. Bakunin's increasing radicalism ended hopes of a professorial career. He was expelled from France for opposing the Russian Empire's occupation of Poland. After participating in the 1848 Prague and 1849 Dresden uprisings, Bakunin was imprisoned, tried, sentenced to death, and extradited multiple times. Finally exiled to Siberia in 1857, he escaped via Japan to the United States and then to London, where he worked with Alexander Herzen on the journal Kolokol (The Bell). In 1863, Bakunin left to join the insurrection in Poland, but he failed to reach it and instead spent time in Switzerland and Italy.
In 1868, Bakunin joined the International Workingmen's Association, leading the anarchist faction to rapidly grow in influence. The 1872 Hague Congress was dominated by a struggle between Bakunin and Marx, who was a key figure in the General Council of the International and argued for the use of the state to bring about socialism. In contrast, Bakunin and the anarchist faction argued for the replacement of the state by federations of self-governing workplaces and communes. Bakunin could not reach the Netherlands, and the anarchist faction lost the debate in his absence. Bakunin was expelled from the International for maintaining, in Marx's view, a secret organisation within the International, and founded the Anti-Authoritarian International in 1872.
