The collection of correspondence of Hüseyin Hilmi Pasha, who was the Grand Vizier at the time of the March 31st Incident, is an important source for researchers interested in late Ottoman history, the Committee of Union and Progress, the Balkans and Macedonia. Hüseyin Hilmi Pasha's official and personal correspondence is an important primary source for national and international political developments in the Balkans, especially during his Rumelia Inspectorate. The documents from this inspectorate period account for more than half of the collection.
Hüseyin Hilmi PaşaProf. Dr. Muḥammad b. Tāwīt al-Ṭanjī (1918-1974) was a Moroccan scholar of literature, fiqh, and history known for his scholarly publications. The collection includes works on history, literature, philosophy, hadith, astronomy, and many other subjects. The collection, which consists of notebooks, miscellaneous documents, and bibliographic fiches, is organized in three groups. Notebooks constitute a significant portion of the 550 documents. These notebooks, which largely contain academic notes, include bibliographical information, indexes, and various works, as well as research that al-Ṭanjī started but did not complete. The miscellaneous papers include 189 letters. The collection, which dates from 1814 to 1997, is classified in 96 folders and 768 files.
Muhammed b. Tavit et-TancîWhen the heir apparent Yusuf İzzeddin Efendi passed away in 1916, Mehmed Tevfik Bey (Biren) assumed the administration of his estate as guardian. The documents, which were shaped around issues such as the distribution of income among family members, expenditures made, and the administration of the estate, reached a significant volume and eventually became an independent collection. The collection, consisting of 4,048 documents produced between 1916 and 1968, is organized in 17 folders and 1,330 files.
