Russian revolutionary and Soviet politician.
Chairman of the Communist International in the 1920s.
As head of the Communist International, Zinoviev’s efforts to mobilize communist revolution abroad failed. His involvement in providing aid to German communists attempting to overthrow the Weimar Republic vilified him in the international eye.
He was eventually executed in Stalin’s Great Purge.
