In 1901, Cemaleddin Dağıstani, a newly enrolled student at a madrasa in Bursa, sent a letter to his family in the district of Quba (now in Azerbaijan) in the Russian Empire. He excitedly shared what he had witnessed during his journey to the Ottoman Empire. Upon crossing the Russo–Ottoman border from Batum (now Batumi, Georgia) to Rize, he was met by Ottoman officials who registered him as a muhajir (refugee or immigrant). Alongside other muhajirs from Russia, including Circassians, Dagestanis, Tatars, and Muslim Georgians, he boarded a state ferry to Istanbul. In seven days, he arrived at the Ottoman capital. He recalled meeting Muslim refugees from Bulgaria, Greece, and Habsburg-occupied Bosnia, and Muslim subjects of the British, French, and German colonial empires. The lion’s share of muhajirs, however, like Cemaleddin, were former Russian subjects. In his letter, Cemaleddin marveled that at times of need Muslims from all over the world sought and found refuge in the Ottoman domains.1
