On September 4, 1888, a murder took place on the premises of Yıldız Palace. Nedim Agha, the senior black eunuch, shot with a revolver and killed another black eunuch, Firuz Agha, who was his junior in rank. After the legal investigation, Nedim Agha was immediately put on trial, both before military and sharia courts, convicted, and publicly hanged in Besiktas, one of the central neighborhoods of Istanbul. Information on this incident comes from various sources, including archival records, newspaper clippings, and contemporary memoirs. A closer look at these sources suggests that there was a more general tendency among the authors of newspaper articles and memoirs to reduce black eunuchs to loathsome characters along the lines of gender, race, and sexuality, while archival sources assist us on other matters on which the historical record of the Ottoman nineteenth century is relatively silent: the daily lives of black eunuchs and their interaction with each other. Moreover, the inheritance registers of Nedim and Firuz Aghas provide a window through which we can gather information about their personalities, thus allowing us to engage with questions pertaining to the agency of enslaved Africans.
