Abstract
Microhistory is an original approach to diplomatic history, insofar as it enables us to grasp the connections established between actors with distinct horizons, but located in the same urban society. The study of Ottoman diplomacy in eighteenth-century Vienna thus moves beyond the framework of a history of powers and cultural areas to highlight the particular and common interests of agents with diverse and sometimes multiple languages, religions and affiliations. The joint mobilization of the imperial metropolis' resources by Austrian and Ottoman diplomats connects the city and the court, but also European and Mediterranean diplomatic centers, as well as deeply trans-imperial aristocratic and merchant clienteles within which Vienna is but a rhizome and among which the diplomats evolve. The history of Ottoman diplomacy in Vienna can also be traced back to Pera, Venice and London, as well as Gorizia, Bucharest and Santorini.
