- Committee for State Security
- Komitet gosudarstvennoy bezopasnosti
The KGB was the main security agency for the Soviet Union from 1954 until its collapse in 1991. Formed in 1954 as a direct successor of such preceding agencies as 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.
