"Bulgarian Georgi Dimitrov, Stalin's close confidant and trusted ally, served as secretary general of the Communist International (Comintern) from 1935 to its dissolution in 1943. In this collection of more than fifty top-secret letters, the real workings of the Comintern emerge clearly for the first time. Drawn from classified Soviet archives only recently opened to Russian and American scholars, these letters offer unique insights into Soviet foreign policy and Stalin's attitudes and intentions while the Great Terror of the 1930s was in progress and in the years leading up to the Second World War."--BOOK JACKET.
