Hello All,

I am researching Soviet mass murder from the period starting at the end of the Russian Civil War up until the invasion of Poland in 1939, or from 1922 to mid-1939.

I am aware of the collectivization famines of 1932-1933 and the Great Terror of 1937-1938.

I am curious as to whether there are any reliable statistics on the executions and killings caused:

By the GPU (1922-24)
By the OGPU (1924-31, 1934)
By the NKVD (1934-36, 1939)

Certainly, Stalin believed and/or led others to believe that ethnic minorities in the Soviet Union were a threat, and that there were vast Polish, German and Japanese espionage and subversion conspiracies.

Thank you and much appreciated.
