The Kommunarka firing range, former dacha of secret police chief Genrikh Yagoda, was used as a burial ground from 1937 to 1941. Executions may have been carried out there by the NKVD during the Great Terror and until the war started; alternatively, bodies of those shot elsewhere might have been brought there for later interment. As Russian historian Arseny Roginsky explained: "firing range" was a popular euphemism adopted to describe mysterious and closely-guarded plots of land that the NKVD began to set aside for mass burials on the eve of the Great Terror.

Memorial is an international human rights organisation, founded in Russia during the fall of the Soviet Union to study and examine the human rights violations and other crimes committed under Joseph Stalin's reign. Subsequently, it expanded the scope of its research to cover the entire Soviet period.
