This article provides a biographical vignette of the Armenian merchant and diplomat Eḷia of Erzurum (1689–1750?), based on his unpublished Armenian chronicle and personal documents which are housed in Russian archives. Eḷia’s biography demonstrates the growing influence of European missionaries and states in the eighteenth-century Ottoman and Safavid empires, while his documents yield a fresh perspective on late Safavid diplomacy and modes of socialization with Christians. Eḷia suffered twelve years of imprisonment in Russia and great disappointment seeking work in Europe. His last known act was to write a scathing critique of Roman Catholic religion and culture. In sum, Eḷia’s life provides an opportunity for exploring the dynamic of global connection and disconnection in the early modern Islamic world.
