Historians of early modern empires have long been investigating the political, intellectual, and economic ties between the Ottoman Empire and Indian Ocean. Earlier studies focus on the networks of political, economic, and knowledge exchange between these two regions and emphasize the increasing intensity of interactions between the Ottoman Empire and Indian Ocean in the sixteenth and seventeenth centuries. My paper aims to contribute to this literature by investigating the ways in which the Ottoman geographers and ruling elites located Indian Ocean in the Ottoman geographical consciousness and imperial project in the early modern period. Through a historical analysis of a select body of Ottoman geographical and cartographical works on Indian Ocean from sixteenth and seventeenth centuries, my paper will demonstrate the extent to which Ottoman geographers took part in the early modern global networks of knowledge exchange and how participation in these networks formed their ideas about Indian Ocean and its place in Ottoman geographical knowledge. It will argue that the development of a heightened sensitivity to geographical knowledge about Indian Ocean in this period was intimately related to the articulation of the Ottoman claims to universal imperial sovereignty. By narrating and depicting the geographical features of the Ottoman realm and Indian Ocean, Ottoman geographers repositioned their Empire to the center and established links to the geographical boundaries of the known world.
