In 1934, the Government Political Administration (GPU) became known as the Peoples Commissariat for Internal Affairs (NKVD). Later that year the new head of the NKVD, Genrikh Yagoda, arrested Lev Kamenev, Gregory Zinoviev, Ivan Smirnov, and thirteen others and accused them of being involved with Leon Trotsky in a plot to murder Joseph Stalin and other party leaders. All of these men were found guilty and were executed on 25th August, 1936.
