This collection will explore the myriad encounters which have taken place between Iranians and Russian in the nineteenth and twentieth centuries. It will include some discussion of diplomacy and foreign policy but a central objective of the collection will be to widen the scholarly perspective to incorporate an understanding of other types of encounter, whether political, economic, social, cultural, or intellectual, and both friendly and hostile, especially as these developed beyond the official and elite levels. In particular it will attempt to understand the complexities of the impact on Iran of the Russian presence on its northern borders: the very expansion of Tsarist empire during the nineteenth century threatening Iran's independence yet bringing ideas of social-democracy to its doorstep, the Soviet Union in the twentieth century similarly contradictory in its effect, sustaining radical Iranian politics while advancing its own strategic interests.
