The People's Commissariat for Internal Affairs (Russian: Наро́дный комиссариа́т вну́тренних дел, romanized: Naródnyy komissariát vnútrennikh del, pronounced [nɐˈrod.nɨj kə.mʲɪ.sə.rʲɪˈat ˈvnut.rʲɪ.nʲɪx̬ dʲel]), abbreviated NKVD (НКВД listen ), was the interior ministry of the Soviet Union. Established in 1917 as NKVD of the Russian Soviet Federative Socialist Republic, the agency was originally tasked with conducting regular police work and overseeing the country's prisons and labor camps. It was disbanded in 1930, with its functions being dispersed among other agencies, only to be reinstated as an all-union commissariat in 1934.The functions of the OGPU (the secret police organization) were transferred to the NKVD around the year 1930, giving it a monopoly over law enforcement activities that lasted until the end of World War II. During this period, the NKVD included both ordinary public order activities, and secret police activities. The NKVD is known for its role in political repression and for carrying out the Great Purge under Joseph Stalin. It was led by Genrikh Yagoda, Nikolai Yezhov, and Lavrentiy Beria.The NKVD undertook mass extrajudicial executions of citizens, and conceived, populated and administered the Gulag system of forced labour camps. Their agents were responsible for the repression of the wealthier peasantry. They oversaw the protection of Soviet borders and espionage (which included carrying out political assassinations), and enforced Soviet policy in communist movements and puppet governments in other countries, most notably the repression and massacres in Poland in 1937 and 1938 to crush opposition and establish political control.In March 1946 all People's Commissariats were renamed to Ministries. The NKVD became the Ministry of Internal Affairs (MVD).
