Mikhail Alexandrovich Bakunin (30 May [O.S. 18 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.
