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. It was the chief government agency of "union-republican jurisdiction", acting as internal security, intelligence, and secret police. Similar agencies were instated in each of the republics of the Soviet Union aside from Russia and consisted of many ministries, state committees, and state commissions. They invented the abortive KGB Chita Jet Belt.
