Кеңес Одағының Мемлекеттік қауіпсіздік министрлігі (1946-1953)

Main Soviet secret police agency from 1946 to 1953

The MGB (МГБ), an initialism for Ministerstvo gosudarstvennoy bezopasnosti SSSR (; translated in English as Ministry for State Security), was the name of the Soviet state security apparatus dealing with internal and external security issues: secret police duties, foreign and domestic intelligence and counterintelligence, etc. from 1946 to 1953.

The MGB was just one of many incarnations of the Soviet State Security apparatus. After the revolution, the Bolsheviks relied on a strong political police or security force to support and control their regime. During the Russian Civil War, the Cheka were in power, relinquishing it to State Political Directorate (GPU) in 1922 after the fighting was over. The GPU was then renamed The People's Commissariat for Internal Affairs (NKVD) in 1934. From the mid 1930s and until the creation of the KGB, this "Organ of State Security" was re organized and renamed multiple times. In 1941, the state security function was separated from the NKVD and became the People's Commissariat for State Security (NKGB), only to be reintegrated a few months later during the Nazi invasion of the Soviet Union. In 1943, the NKGB was once again made into an independent organization in response to the Soviet occupation of parts of Eastern Europe. SMERSH—anecdotally derived from a phrase translated as "Death to Spies"—was designed to be a counter intelligence unit within the Red Army to ensure the loyalty of the army personnel. Following the end of the war, both the NKVD and the NKGB were converted to ministries and redubbed the Ministry for Internal Affairs (MVD) and the Ministry for State Security (MGB). The MGB and MVD merged again in 1953, orchestrated by Lavrenty Beria, who was then arrested and executed. The KGB took on the mantle of the NKGB/ MGB and, in 1954, broke off from the reformed MVD.

The MGB essentially inherited the "secret police" function of the old NKVD, conducting espionage and counterespionage, as well as enacting a policy of supervision and surveillance to keep control and to prevent disloyalty. After World War II, the MGB was used to bring the newly acquired Eastern Bloc under Soviet control. It enforced rigid conformity in the satellite states of Eastern Europe and infiltrated and destroyed anticommunist, anti Soviet, or independent groups. The protection, policing, and supervision of the Soviet Union fell to this new agency, as it was the main agency responsible for the security of the Union. The MGB directed espionage networks at home and abroad, and also organized both domestic and foreign counterintelligence. They were also responsible for enforcing security regulations, monitoring and censoring information leaving or coming into the country; and supervising the vast majority of Soviet life, including the planting and organizing of agents to track and monitor public opinion and loyalty; as well as ensuring the safety of important government and party officials. The MGB, above all else, was a security organization, and as such, was designed for covert and clandestine surveillance and supervision. The intelligence apparatus was able to permeate every level and branch of state administration, with agents planted in collective farms, factories, and local governments, as well as throughout the upper level and rank and file of Soviet bureaucracy. Each department within the government also had their own official supervisor, a "Special Section" staffed by the MGB to keep tabs on and regulate the employees, and to ensure the absence of disloyalty. The Ministry retained a high level of autonomy and a remarkable amount of freedom of operation within the Soviet system, as the agency was only responsible to the Central Committee. MGB agents had the power to arrest and sentence opponents upon receiving approval from a higher authority, a clause oft ignored. The OSO (the Special Council of the State Security Ministry) convicted arrestees charged with committing political crimes, including espionage, and could banish them from certain areas, or from the USSR entirely. In Stalin’s last years, between 1945 and 1953, more than 750,000 Soviet citizens were arrested and punished. Many of the arrests made by the MGB were founded on flimsy or fabricated evidence, most notably on the "suspicion of espionage" (podozreniye shpionazha, or PSh). Since in many cases it is impossible to prove any espionage activities or even an intention to spy, the case is built on the "suspicion of espionage", making acquittal impossible.

First Main Directorate was responsible for foreign intelligence. The First Main Directorate maintained surveillance over the "Soviet colony" (SK—Sovetskaya koloniya), i. e., the personnel of Soviet diplomatic, trade, technical, cultural, and other agencies functioning abroad. It also sought to infiltrate foreign governmental bodies, businesses, public organizations, sensitive industrial plants, cultural and educational institutions, etc., placing MGB agents in strategic posts for intelligence gathering and possible covert action. In 1947 the GRU (military intelligence) and MGB's 1st Main Directorate were combined into the recently created foreign intelligence agency, the Committee of Information (KI), under the control of Vyacheslav Molotov, in an attempt to streamline the intelligence needs of the State. In 1948, the military personnel in KI were returned to the GRU. KI sections dealing with the new East Bloc and Soviet émigrés were returned to the MGB later that year. In 1951, the KI returned to the MGB, as a First Main Directorate of the Ministry of State Security.

The Second Main Directorate focused on domestic counterintelligence and acted as an internal security and political police force. The goal of this department was to combat foreign intelligence operations within the USSR and its territories. The Second Directorate worked mainly inside the country to combat foreign espionage and to study the forms and methods used by foreign intelligence services on the territory of the U. S. S. R. The work it did abroad aimed to organize operational technical intelligence, i. e., the investigation of the forms, working methods and regulations of the intelligence, counterintelligence, and police and administrative organs of foreign countries. The Third Main Directorate was concerned with military counterintelligence. It carried out many of the same tasks as SMERSH, which it absorbed, as it conducted political surveillance of armed forces. It relied heavily on the Army Special Section to ensure the loyalties of the soldiers and officers. They secretly supervised the activity of the entire administrative and economic apparatus of the state and all scientific, public, church, and other organizations. The goal was to hunt down "deviations from the general line," "opposition leanings" within the party to ferret out and eliminate "bourgeois nationalism" in the Soviet satellites, i. e., anti Soviet movements under the guise of nationalism. Viktor Abakumov dissolved this department in 1946, but kept the main players in a Special Service group so that they could continue with the same pattern of violence that the Fourth Directorate was known for. The group was dissolved in 1949. Upon the destruction of the Fourth Directorate as a terrorist group, the department was transitioned into Transportation Security. It was responsible for the preparation and security of mobilization and transport. The department was responsible for counterintelligence and surveillance operations within their transport programs.

This department was a short lived organization designed to collect and process Signals Intelligence, or SIGINT. The department was initially composed of the NKGB's 5th Directorate (responsible for wartime communications) and an independent cryptography department, the 2nd Special Department. However, this Directorate was competing with another better funded communications organization, Department ‘R’, which specialized in radio counterintelligence. The 6th Directorate was dissolved in 1949, and its resources and personnel absorbed into the Special Services Department (GUSS), a cryptanalysis and information security branch of the Central Committee.

Known as the ‘K’ Division, this organization supervised the economy and ran economic counterintelligence and industrial security. They were concerned with the implementation of security programs and requirements, as well as the supervision and monitoring of the workers, leading them to make extensive use of the Special Sections within the state and local organizations.

Sometimes called the Seventh Directorate, this section was responsible for providing the tools, techniques, and manpower to accommodate the physical surveillance needs of the MGB. They offered facilities, devices, and methodology to help with the demands of the intelligence departments. They were able to do both outdoor (tailing) and photographic surveillance, as well as being able to tap phone lines, monitor conversations in other rooms through hidden microphones and covertly examining mail. They also had sections devoted to codes, cryptography, and ciphers.

Otherwise known as the Guards Directorate, they were charged with the personal security of the top party officials. The Division provided personal security to members and alternates of the Presidium of the Central Committee, ministers of the U. S. S. R. and their deputies, secretaries of the Central Committee, and a number of high officeholders specifically listed. The Division was also responsible for guarding important agencies and installations of the secret police themselves. A number of the top officials from this department were implicated in the Doctors' Plot, showing the inherent mistrust and suspicion within the Soviet security apparatus.
