During the Second World War and its immediate aftermath the Soviet All-Union Society for Cultural Ties Abroad (VOKS) engaged in an aggressive campaign of cultural outreach in Iran to promote socialist modernity amongst Iranian leftists. Iran represented VOKS’ first serious expansion outside Europe and one which the Soviet Union was uniquely poised to exploit. VOKS tapped into the Soviet Union's orientalist scholarly establishment inherited from the Russian Empire to advance the argument that not only were Iran and the Soviet Union geographically contiguous, they were both inheritors of the same Persianate cultural legacy—ironically a legacy that the Soviet Union had actively displaced in favor of Turkic national SSRs. Meanwhile, Iranian leftists were not passive receivers of Soviet propaganda. They exploited VOKS resources to found the Iranian Society for Cultural Relations with the USSR and establish regional branches throughout the country. In particular, Iranian intellectuals fixated on Soviet Azerbaijan and Uzbekistan as evidence of the abundant possibilities for a specifically Persianate articulation of socialist modernity. This article uses both Russian archival sources and Persian-language periodicals and interview transcripts to explore this unique confluence of Soviet and Iranian ambitions.
