The KGB, also known as the Soviet Secret Police, was a highly feared intelligence agency responsible for suppressing dissent and enforcing Soviet ideology during the Cold War. Synonyms for the KGB include the Committee for State Security, the Cheka, the NKVD, and the MGB. These organizations were all predecessors to the KGB and were established at different points in Soviet history. Each had its own specific functions, but all were characterized by their brutal tactics, including torture, imprisonment, and execution. Despite the KGB's dissolution in 1991, its legacy continues to shape modern-day Russia and international politics.
