Despite the appalling record of the Soviet Union on human rights questions, many western intellectuals with otherwise impeccable liberal credentials were strong supporters the Soviet Union in the interwar period. This book explores how this seemingly impossible situation came about. Focusing in particular on the work of various official and semi-official bodies, including Comintern, the International Association of Revolutionary Writers, the All-Union Society for Cultural Relations with Foreign Countries, and the Foreign Commission of the Soviet Writers' Union, this book shows how cultural propaganda was always a high priority for the Soviet Union, and how successful this cultural propaganda was in seducing so many Western thinkers.
