The People's Commissariat for Internal Affairs (Народный комиссариат внутренних дел, Narodnyy Komissariat Vnutrennikh Del), abbreviated NKVD (НКВД  listen (help·info)) was the public and secret police organization of the Soviet Union that directly executed the rule of power of the Soviets, including political repression, during the era of Joseph Stalin.

The NKVD contained the regular, public police force of the USSR (including traffic police, firefighting, border guards and archives) but is better known for the activities of the Gulag and the Main Directorate for State Security (GUGB), which eventually became the Committee for State Security (KGB). It conducted mass extrajudicial executions, ran the Gulag system of forced labor camps, suppressed underground resistance, conducted mass deportations of entire nationalities and Kulaks to unpopulated regions of the country, guarded state borders, conducted espionage and political assassinations abroad, was responsible for influencing foreign governments, and enforced Stalinist policy within communist movements in other countries.

Ayn Rand ( /ˈaɪn ˈrænd/; born Alisa Zinov'yevna Rosenbaum, February 2 [O.S. January 20] 1905 – March 6, 1982) was a Russian-American novelist, philosopher, playwright, and screenwriter. She is known for her two best-selling novels The Fountainhead and Atlas Shrugged and for developing a philosophical system she called Objectivism.

Born and educated in Russia, Rand moved to the United States in 1926. She worked as a screenwriter in Hollywood and had a play produced on Broadway in 1935–1936. After two initially unsuccessful early novels, she achieved fame with her 1943 novel The Fountainhead. In 1957, she published her best-known work, the philosophical novel Atlas Shrugged. Afterward she turned to nonfiction to promote her philosophy, publishing her own magazines and releasing several collections of essays until her death in 1982.

Rand advocated reason as the only means of acquiring knowledge and rejected all forms of faith and religion. She supported rational and ethical egoism, and rejected ethical altruism. In politics, she condemned the initiation of force as immoral and opposed all forms of collectivism and statism, instead supporting laissez-faire capitalism, which she believed was the only social system that protected individual rights. She promoted romantic realism in art. She was sharply critical of the philosophers and philosophical traditions known to her besides Aristotle.

Joseph Vissarionovich Stalin (Russian: Иосиф Виссарионович Сталин; born Iosif Vissarionovich Dzhugashvili, Russian: Иосиф Виссарионович Джугашвили; 18 December 1878 – 5 March 1953) was the Premier of the Soviet Union from 6 May 1941 to 5 March 1953. He was among the Bolshevik revolutionaries who brought about the October Revolution in Russia in 1917 and later held the position of General Secretary of the Communist Party of the Soviet Union's Central Committee from 1922 until his death in 1953. While the office of the General Secretary was officially elective and not initially regarded as the top position in the Soviet state, Stalin managed to use it to consolidate more and more power in his hands after the death of Vladimir Lenin in 1924 and gradually put down all opposition groups within the Communist Party. This included Leon Trotsky, a socialist theorist and the principal critic of Stalin among the early Soviet leaders, who was exiled from the Soviet Union in 1929. Whereas Trotsky was an exponent of permanent revolution, it was Stalin's concept of socialism in one country that became the primary focus of Soviet politics.

Lavrentiy Pavlovich Beria (Georgian: ლავრენტი პავლეს ძე ბერია, Lavrenti Pavles dze Beria; Russian: Лавре́нтий Па́влович Бе́рия; 29 March 1899 – 23 December 1953) was a Soviet politician, Marshal of the Soviet Union and state security administrator, chief of the Soviet security and secret police apparatus (NKVD) under Joseph Stalin during World War II, and Deputy Premier in the postwar years (1946–1953).

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. He simultaneously administered vast sections of the Soviet state and served as de facto Marshal of the Soviet Union in command of the NKVD field units responsible for anti-partisan operations on the Eastern Front during World War II, as well as for acting as barrier troops and the apprehension of thousands of "turncoats, deserters, cowards and suspected malingerers". Beria administered the vast expansion of the Gulag labor camps and was primarily responsible for overseeing the secret defense institutions known as sharashkas, critical to the war effort. He also played the decisive role in coordinating the Soviet partisans, developing an impressive intelligence and sabotage network behind German lines. He attended the Yalta Conference with Stalin, who introduced him to U.S. President Franklin D. Roosevelt as "our Himmler". After the war, he organized the communist takeover of the countries of Central Europe and Eastern Europe. Beria's uncompromising 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 in no small part due to Soviet espionage against the West organized by Beria's NKVD.
