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 Russia's occupation of Poland. In 1849, he was arrested in Dresden for his participation in the Czech rebellion of 1848 and deported to Russia, where he was imprisoned first in Saint Petersburg, then in the Shlisselburg fortress from 1854 and 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.
