Federal Counterintelligence Service

The Federal Counterintelligence Service of the Russian Federation (FSK RF; Федеральная служба контрразведки Российской Федерации) was the main security agency of Russia. It superseded the Ministry of Security of the Russian Federation, and was an overall successor agency to the Soviet Union's KGB, which had dissolved two years prior to the FSK’s creation. It existed from 1993 to 1995, when it was reorganized into the Federal Security Service (FSB).

Origin
On November 26, 1991, the President of the RSFSR Boris Yeltsin issued a decree on the transformation of the republican State Security Committee (KGB) into the Federal Security Agency of the RSFSR (AFB). On January 24, 1992, by decree of the President of Russia, the Ministry of Security of the Russian Federation was created on the basis of the abolished Federal Security Agency of the RSFSR and the Inter-Republican Security Service of the USSR.

On December 21, 1993, by decree of the President of the Russian Federation, the Ministry of Security was abolished and the Federal Counterintelligence Service of the Russian Federation (FSK) was created in its place.
