Andreu Nin

Andreu Nin i Pérez (Spanish: Andrés Nin Pérez; 4 February 1892 – 20 June 1937) was a Spanish politician, trade unionist and translator. He is mainly known for his role in various Spanish left-wing movements of the early 20th century and, later, for his role in the Spanish Civil War. He is also known for his work translating Russian classics such as Ana Karenina, Crime and Punishment and some works by Anton Chekhov, from Russian into Catalan.

A teacher and journalist, during his youth he was involved in various political movements until he joined the anarchist Confederación Nacional del Trabajo (CNT). During his stay in Russia, he witnessed the Russian Revolution, which marked his conversion to Marxism. After his return to Spain, he later became one of the founders of the small but active Workers' Party of Marxist Unification (POUM). He eventually became a leading figure in Spanish revolutionary Marxism. He disappeared during the course of the Spanish Civil War, having been arrested by the Republican authorities following the "May Days".
