Lavrentiy Beria, Georgian-Russian general and politician (d. 1953)
Lavrentiy Pavlovich Beria (; Russian: Лавре́нтий Па́влович Бе́рия, tr. Lavréntiy Pávlovich Bériya, IPA: [ˈbʲerʲiə]; Georgian: ლავრენტი ბერია, romanized: lavrent'i beria, IPA: [bɛriɑ]; 29 March [O.S. 17 March] 1899 – 23 December 1953) was a Georgian Bolshevik and Soviet politician, Marshal of the Soviet Union and state security administrator, chief of the Soviet security, and chief of the People's Commissariat for Internal Affairs (NKVD) under Joseph Stalin during World War II, and promoted to deputy premier under Stalin from 1941. He later officially joined the Politburo in 1946.

Beria was the longest-lived and most influential of Stalin's secret police chiefs, wielding his most substantial influence during and after World War II. Following the Soviet invasion of Poland in 1939, he was responsible for organizing purges such as the Katyn massacre of 22,000 Polish officers and officials. Beria would later also orchestrate the forced upheaval of minorities from the Caucasus as head of NKVD, an act that was declared as genocidal by various scholars and, as concerning Chechens, in 2004 by the European parliament. He simultaneously administered vast sections of the Soviet state, and acted as the de facto Marshal of the Soviet Union in command of NKVD field units responsible for barrier troops and Soviet partisan intelligence and sabotage operations on the Eastern Front during World War II. Beria administered the expansion of the Gulag labour camps, and was primarily responsible for overseeing the secret detention facilities for scientists and engineers known as sharashkas.

After the war, he organised the communist takeover of the state institutions in central and eastern Europe. Beria's ruthlessness in his duties and skill at producing results culminated in his success in overseeing the Soviet atomic bomb project. Stalin gave it absolute priority, and the project was completed in under five years.After Stalin's death in March 1953, Beria became First Deputy Chairman of the Council of Ministers and head of the Ministry of Internal Affairs. In this dual capacity, he formed a troika with Georgy Malenkov and Vyacheslav Molotov that briefly led the country in Stalin's place.

A coup d'état by Nikita Khrushchev, with help from Marshal of the Soviet Union Georgy Zhukov, in June 1953 removed Beria from power. After being arrested, he was tried for treason and other offenses, sentenced to death, and executed on 23 December 1953. During his trial, and after his death, numerous allegations arose of Beria being a serial rapist and serial killer.
