Cheka

The Cheka followed on from the Imperial Russian Secret Police (Czarist Ochrana) in the aftermath of the Bolshevik take over.

Cheka - 1917 to 1922
QUOTE
The Cheka ( Extraordinary Commission ) was the first of a succession of Soviet state security organizations. It was created by a decree issued on December 20, 1917, by Vladimir Lenin and subsequently led by aristocrat turned communist Felix Dzerzhinsky. After 1922, the Cheka underwent a series of reorganizations into bodies whose members continued to be referred to as "Chekisty" (Chekists) into the late 1980s.

From its founding, the Cheka was an important military and security arm of the Bolshevik communist government. In 1921 the Troops for the Internal Defense of the Republic (a branch of the Cheka) numbered 200,000. These troops policed labor camps, ran the Gulag system, conducted requisitions of food, subjected political opponents (on both the right and the left) to torture and summary execution, put down (peasant) rebellions, riots by workers, and mutinies in the Red Army, which was plagued by desertions.

The Wiki gives a low key view of their evil.
The Wiki has its very own agenda.

The Mitrokhin Archive at page 30 et seq tells us that in the early days of the Cheka it was amateurish. It learned from  the Ochrana and experience. It was also paranoid about foreign conspiracies from the start, getting worse with time especially under Stalin.

Trotsky And The Cheka
QUOTE
After the Bolsheviks had seized power, Trotsky declined Lenin’s offer to be party leader, choosing instead the post of commissar of foreign affairs and then commissar of the Red Army, which he commanded with an iron hand during the subsequent civil war. The Bolsheviks’ crackdown on dissent began almost immediately, however, and in it Trotsky adopted − and long afterward defended − the proposition that to safeguard the revolution ‏(meaning the Bolsheviks’ one-party rule‏), any means was justified, including mass executions and hellish exile to cow dissidents of all stripes. With Trotsky’s conversion to Bolshevik orthodoxy, Rubenstein observes almost angrily, “the country was now in the hands of determined Marxists who would stop at nothing to hold onto power and impose their ideological views.”.............

After the Bolshevik revolution, however, Trotsky apparently regarded his Jewish origin as a handicap. When Lenin urged him to accept the position of commissar of home affairs, for example, Trotsky declined for fear that placing a Jew in the role of the regime’s “chief enforcer” would hand the enemies of the revolution “a useful tool,” in Rubenstein’s words. And during the civil war, he fretted, presumably for the same reason, over the relatively high number of Jews in the Cheka ‏(secret police‏).

This review was written by a Jew, for Jews about a Jew. They are prone to tell the truth among themselves.
