The KGB (Komitet gosudarstvennoy bezopasnosti) was the main security and intelligence agency of the Soviet Union from 1954 to 1991, serving as the “sword and shield of the Communist Party” . It inherited the functions of earlier secret police bodies such as the Cheka, GPU, OGPU, NKVD, and MGB .
Structure and Directorates
The KGB was organized into chief directorates and specialized units, each with distinct responsibilities :
First Chief Directorate (Foreign Operations) – Conducted foreign intelligence, covert operations, and political, scientific, and technological intelligence gathering. It included geographic departments, training units, and a special forces group (spetsnaz) for reconnaissance and sabotage .
The Committee for State Security (Russian: Комитет государственной безопасности, romanised: Komitet gosudarstvennoy bezopasnosti, IPA: [kəmʲɪˈtʲed ɡəsʊˈdarstvʲɪn(ː)əj bʲɪzɐˈpasnəsʲtʲɪ]), abbreviated as KGB (Russian: КГБ, IPA: [ˌkɛɡɛˈbɛ]; ⓘ) was the main security agency of the Soviet Union from 1954 to 1991. It was the direct successor of preceding Soviet secret police agencies including the Cheka, OGPU, and NKVD. Attached to the Council of Ministers, it was the chief government agency of "union-republican jurisdiction", carrying out internal security, foreign intelligence, counter-intelligence and secret police functions. Similar agencies operated in each of the republics of the Soviet Union aside from the Russian SFSR, where the KGB was headquartered, with many associated ministries, state committees and state commissions.
