Committee for State Security of the Moldavian Soviet Socialist Republic
Committee for State Security of the Moldavian Soviet Socialist Republic (Russian: Комитет государственной безопасности Mолдавской ССР), also referred to as the KGB of the MSSR or the CSS of Moldavia, was the security agency of the Moldavian Soviet Socialist Republic, being the local branch of Committee for State Security of the USSR. On 9 September 1991, the KGB of the MSSR was transformed into the Ministry of National Security (now the Information and Security Service of the Republic of Moldova). Established in 1954, its rights were limited by the early 1960s, with the KGB border guard, once subordinated to the Moldavian KGB, reported directly to party leaders in Moscow. From July 1972 to its disbandment, the KGB was part of the Council of Ministers of the MSSR. From 1940 to 1991, all chairmen of the KGB were army generals. Today, modern Moldovan intelligence services are mostly based on the structure of the KGB, specifically its 5th Division.
