Pyotr Alexeevich Kropotkin (/kroʊˈpɒtkɪn, krə-/; Russian: Пётр Алексе́евич Кропо́ткин; December 9, 1842 – February 8, 1921) was a Russian activist, revolutionary, scientist and philosopher who advocated anarcho-communism.
Born into an aristocratic land-owning family, he attended a military school and later served as an officer in Siberia, where he participated in several geological expeditions. He was imprisoned for his activism in 1874 and managed to escape two years later. He spent the next 41 years in exile in Switzerland, France (where he was imprisoned for almost four years) and in England. He returned to Russia after the Russian Revolution in 1917, but was disappointed by the Bolshevik form of state socialism.
