Reform efforts that started in the military field in the Ottoman Empire gained a new dimension in the 19th century. In this period, the scope of the reforms exceeded the military field and directly affected the administrative structure. In particular, from 1836, when the Ministry of Foreign Affairs was established, to 1871, the foreign staff played an active role in the reform processes. Therefore, the Ministry of Foreign Affairs gained the function of a bridge through reforms which were transferred to the Empire. In this article, the traces of the personnel of the Ministry of Foreign Affairs on the reforms made in the fields of administration, justice, finance, economy, education and military were examined. By following these traces through examples, the claim that the Ministry of Foreign Affairs was effective in reforms in other institutions was tested.
