NKVD

The NKVD came after OGPU which was the successor to the Cheka, the secret police under the Bolsheviks. Jews of the outfit controlled the slaves building the White Sea Canal at a cost of thousands dead. They also attacked private entrepreneurs, robbing, arresting, kicking them out of their homes. See The Jewish Century at page 221, written by a Jew from Russia on the point. There is a full listing at the Chronology of Soviet secret police agencies.

The OGPU became the NKVD in 1937 when QUOTE Jews "by nationality" constituted the largest single group among the "leading cadres" of the Soviet secret police (37 Jews, 30 Russians, 7 Latvians, 5 Ukrainians, 4 Poles, 3 Georgians, 3 Belorussians, 2 Germans and 5 assorted others). Twelve key NKVD departments and directorates, including those in charge of the police (worker-peasant militia), labor camps (Gulag), counterintelligence, surveillance, and economic wrecking were headed by Jews, all but two of them from the former Pale of Settlement. The people's commissar of internal affairs was Genrikh Grigorevich Yagoda UNQUOTE ex Page 224 of The Jewish Century by Yuri Slezkine, a Jew from Russia

State Political Directorate (OGPU)
QUOTE
Perhaps the most spectacular success of the GPU/OGPU was the Trust Operation of 1924-1925. OGPU agents contacted émigrés in western Europe and pretended to be representatives of a large group working to overthrow of the communist regime, known as the "Trust". Exiled Russians gave the Trust large sums of money and supplies, as did foreign intelligence agencies. The Trust finally succeeded in luring one of the leading anti-Communist operators, Sidney Reilly, into Russia to meet with the Trust. Once he was in Russia, he was captured and killed. The Trust was dissolved, and it became a large propaganda success......

The OGPU was responsible for the creation of the Gulag system. It also became the Soviet government's arm for the persecution of the Russian Orthodox Church, the Greek Catholics, the Latin Catholics, Islam and other religious organizations, an operation headed by Yevgeny Tuchkov. The OGPU was also the principal secret police agency responsible for the detection, arrest, and liquidation of anarchists and other dissident left-wing factions in the early Soviet Union. Gradually, its de facto powers became even greater than those of the Cheka.

The OGPU was reincorporated into the newly-created all-union People's Commissariat for Internal Affairs (NKVD) in July 1934, becoming its Main Directorate of State Security (GUGB). Its final transformation was into the more widely known Committee for State Security (KGB).
