In response to the growing demands of diplomacy within the increasingly institutionalized Ottoman diplomatic framework, a significant expansion in the number of diplomats employed by the state was observed during the final quarter of the nineteenth century. Concurrent with the rapid increase in diplomatic personnel, a systematic appointment process was implemented to enhance the recruitment of qualified and knowledgeable individuals. This study aims to examine the impact of the institutionalization of the Ottoman Ministry of Foreign Affairs on its ambassadors and consuls, who were the principal executive officers of the institution. Additionally, the article explores the social histories of Ottoman ambassadors and consuls by analyzing the evolution of their professional responsibilities and educational backgrounds. This study employs a prosopographic methodology to investigate the social and educational backgrounds and professional careers of Ottoman ambassadors and consuls, focusing on their personnel records archived in the Ottoman Archives. Through this analysis, the study aims to elucidate how the state's efforts to establish a centralized and institutionalized bureaucratic system, and to emphasize merit-based appointments, contributed to the formation of a distinct professional identity among Ottoman diplomats by the end of the nineteenth century.
