This 1936 pamphlet is a vital historical document of Soviet diplomacy during the interwar period. Published by Partizdat, it contains the full text of the speech delivered by Maxim Maximovich Litvinov (1876–1951) at the Extraordinary VIII All-Union Congress of Soviets—the same congress that adopted the 1936 "Stalin Constitution." At the time, Litvinov served as the People's Commissar for Foreign Affairs (1930–1939) and was the international face of the Soviet policy of "Collective Security."
The speech was delivered at a critical juncture in European history. With the rise of Nazi Germany and the outbreak of the Spanish Civil War, Litvinov used this platform to articulate the USSR's stance against fascist aggression. Together with his colleagues, such as French Foreign Minister Louis Barthou and Czechoslovakian leader Edvard Beneš, Litvinov was the primary architect of a proposed alliance between the USSR and Western democracies. In this speech, he frames the Soviet Union not merely as a socialist state, but as the "mighty bulwark" essential to preventing a second global conflict.
Historical Significance: This publication reflects the peak of the "Litvinov Line" before the eventual failure of collective security led to his dismissal in 1939 and the subsequent Molotov-Ribbentrop Pact. The pamphlet is a primary source for understanding the specialized rhetoric of pre-war Soviet foreign policy, where the language of revolutionary struggle was increasingly blended with the pragmatism of anti-fascist diplomacy.
For historians of international relations, collectors of Soviet political ephemera, and researchers of the League of Nations era, this 32-page brochure is an essential artifact. It represents a brief window in time when the USSR sought integration into the European security framework to contain the "aggressive plans of Nazi Germany."
