For half a century, under strict secrecy, the archives of the Ministry of Foreign Affairs have kept the most important diplomatic documents on the history of Soviet-German relations on the eve of the Great Patriotic War. Official publications of USSR MFA documents stopped at the fatal date—August 1939. And it is no accident: this month the non-aggression pact was signed between the Soviet Union and Hitler’s Germany.
In this collection, the most important documents and materials of the German Ministry of Foreign Affairs are published concerning Soviet-German relations from April 1939 to June 1941.
