After the close of World War II, 24 senior leaders of the Einsatzgruppen were prosecuted in the Einsatzgruppen Trial in 1947–48, part of the Subsequent Nuremberg Trials held under United States military authority. The men were charged with crimes against humanity, war crimes, and membership in the SS (which had been declared a criminal organization). Fourteen death sentences and two life sentences were among the judgments; only four executions were carried out, on 7 June 1951; the rest were reduced to lesser sentences.
