The Securitate (sekuriˈtate, Romanian for security) was the popular term for the Departamentul Securității Statului (Department of State Security), the secret police agency of the Socialist Republic of Romania. Previously, before the communist regime, Romanian secret police was called Siguranța Statului. It was founded on 30 August 1948, with help and direction from the Soviet MGB. Following the overthrow of Nicolae Ceaușescu in 1989, the new authorities assigned the various intelligence tasks of the DSS to new institutions.
The Securitate was, in proportion to Romania's population, one of the largest secret police forces in the Eastern bloc. The first budget of the Securitate in 1948 stipulated a number of 4,641 positions, of which 3,549 were filled by February 1949: 64% were workers, 4% peasants, 28% clerks, 2% persons of unspecified origin, and 2% intellectuals. By 1951, the Securitate's staff had increased fivefold, while in January 1956, the Securitate had 25,468 employees. At its height, the Securitate employed some 11,000 agents and had half a million informers for a country with a population of 22 million by 1985. Under Ceaușescu, the Securitate was one of the most brutal secret police forces in the world, responsible for the arrests, torture, and deaths of thousands of people.
The General Directorate for the Security of the People (Romanian initials: DGSP, but more commonly just called the Securitate) was officially founded on 30 August 1948, by Decree 221/30 of the Presidium of the Great National Assembly. However, it had precursors going back to August 1944, following the coup d'état of 23 August. Its stated purpose was to "defend democratic conquests and guarantee the safety of the Romanian People's Republic against both internal and external enemies."
The Securitate was created with the help of SMERSH, the NKVD counter-intelligence unit. The SMERSH operation in Romania, called Brigada Mobilă ("The Mobile Brigade"), was led until 1948 by NKVD colonel Alexandru Nicolschi.
