Count Lev Nikolayevich Tolstoyɪvʲɪtɕ tɐlˈstoj] ; 9 September [O.S. 28 August] 1828 – 20 November [O.S. 7 November] 1910), usually referred to in English as Leo Tolstoy, was a Russian writer. He is regarded as one of the greatest and most influential authors of all time.
Born to an aristocratic family, Tolstoy achieved acclaim in his twenties with his semi-autobiographical trilogy, Childhood, Boyhood and Youth (1852–1856), and with Sevastopol Sketches (1855), based on his experiences in the Crimean War. His War and Peace (1869), Anna Karenina (1878), and Resurrection (1899), which is based on his "youthful sins," are often cited as pinnacles of realist fiction and three of the greatest novels ever written. His oeuvre includes short stories such as "Alyosha the Pot" (1911) and "After the Ball" (1911) and novellas such as Family Happiness (1859), The Death of Ivan Ilyich (1886), The Kreutzer Sonata (1889), The Devil (1911), and Hadji Murat (1912).
