Interior ministry in the context of Ministry of Home Affairs (Indonesia)

The Great Purge or Great Terror (Russian: Большой террор, romanized: Bol'shoy terror), also known as the Year of '37 (37-й год, Tridtsat' sed'moy god) and the Yezhovshchina (ежовщина [(j)ɪˈʐofɕːɪnə], lit. 'period of Yezhov'), was a political purge in the Soviet Union from 1936 to 1938. After the assassination of Sergei Kirov by Leonid Nikolaev in 1934, Joseph Stalin launched a series of show trials known as the Moscow trials to remove suspected dissenters from the Communist Party of the Soviet Union (especially those aligned with the Bolshevik party). The term "great purge" was popularized by historian Robert Conquest in his 1968 book, The Great Terror, whose title alluded to the French Revolution's Reign of Terror.

The purges were largely conducted by the NKVD (People's Commissariat for Internal Affairs), which functioned as the interior ministry and secret police of the USSR. In 1936, the NKVD under Genrikh Yagoda began the removal of the central party leadership, Old Bolsheviks, government officials, and regional party bosses. Soviet politicians who opposed or criticized Stalin were removed from office and imprisoned, or executed, by the NKVD. The purges were eventually expanded to the Red Army high command, which had a disastrous effect on the military. The campaigns also affected many other segments of society: the intelligentsia, wealthy peasants—especially those lending money or other wealth (kulaks)—and professionals. As the scope of the purge widened, the omnipresent suspicion of saboteurs and counter-revolutionaries (known collectively as wreckers) began affecting civilian life.

The Ministry of Internal Affairs of the USSR (MVD; Russian: Министерство внутренних дел СССР (МВД), romanized: Ministerstvo vnutrennikh del SSSR) was the interior ministry of the Soviet Union from 1946 to 1991. The MVD was established as the successor to the NKVD during the reform of the People's Commissariats into the Ministries of the Soviet Union in 1946 as part of a broader restructuring of the government. The MVD did not include agencies concerned with secret policing unlike the NKVD, with the function being assigned to the Ministry of State Security (MGB), which had been established during the Second World War. The MVD and MGB were briefly merged into a single ministry from March 1953 until the MGB was split off as the Committee for State Security (KGB) in March 1954.

This resulted in a system where one agency was responsible for domestic and foreign intelligence gathering, espionage, surveillance and secret police functions, and another responsible for the regular civilian police forces, fire departments and internal security troops. The MVD was headed by the Minister of Internal Affairs and responsible for many internal services in the Soviet Union such as the Militsiya, the national police force, the Internal Troops, which served as the USSR's national gendarmerie, the OMON riot control units, Traffic Safety, prisons, the Gulag system as well as the successive penal colonies, and the internal migration system. From 1966-1968, it was briefly known as the Ministry of Public Order Protection. The MVD was dissolved upon the dissolution of the Soviet Union in December 1991 and succeeded by its branches in the post-Soviet states, the largest being the Russian MVD, which inherited its predecessor's functions, though its Internal Troops would later become their own independent service - the National Guard.
