The KGB, an initialism for Komitet gosudarstvennoy bezopasnosti (Russian: Комите́т госуда́рственной безопа́сности (КГБ); IPA: [kəmʲɪˈtʲɛt ɡəsʊˈdarstʲvʲɪnnəj bʲɪzɐˈpasnəsʲtʲɪ], translated in English as Committee for State Security), was the main security agency for the Soviet Union from 1954 until its break-up in 1991. Formed in 1954, as a direct successor of such preceding agencies as the Cheka, NKGB, and MGB, the committee was attached to the Council of Ministers.
