The Ministry of State Security (MGB) ( Russian: Министерство государственной безопасности (Ministerstvo Gosudarstvennoi Bezopasnosti)) was the name of the Soviet secret police agency from 1946 to 1953. The East German secret police agency, the Stasi, was also named "Ministry for State Security" and it is likely that it adopted the name of the agency that influenced it.
