By the second half of the nineteenth century a significant number of Iranian dissidents, literary figures and men of letters considered the Ottoman Empire, and specifically its capital Istanbul, their home and the seat of their socio-intellectual base. This community formed a highly active opposition base involved in Iranian politics from abroad. Although the significance of Ottoman reforms on Qajar Iran have been acknowledged in the literature by a range of scholars, no more than a certain amount of background material can be found concerning the network of Iranians residing in nineteenth-century Istanbul, and no significant work has yet been carried out on the impact of this community on political, social and literary reform in Iran. From disparate sites such as Istanbul, Bursa and Mosul the likes of men such as Mirza Habib Isfahani, Mirza Aqa Khan Kirmani, Malkum Khan and Zaynolabedin Maragha’i produced and published much of the dissent literature that two decades later would be hailed as being amongst the most important texts circulated prior to the Constitutional Revolution (1905-1907). Notable is that although these men spent considerable proportions of their careers in the Ottoman Empire, very little information on their ‘Ottoman’ lives is available, primarily because the Ottoman Archives as a depository for Qajar history has been overlooked. Drawing on material from the Ottoman Archives, this paper will discus the chains of interconnectedness that made possible the formation of expansive intellectual and social networks within and across the late Ottoman Empire. In an attempt to recover the distinct and variant perspectives from within this Iranian community, the paper will focus on personal exchange and circumstance, travel, and the diffusion and reception of ideas to highlight that social context, as well as economic and political power relations determined the nature of one’s intellectual labor.
