Focusing on the years between 1895 and 1897, this article reconstructs what happened after the arrival of Young Turk revolutionaries into the cities of the Danubian hinterland, particularly centering on Rusçuk (Ruse in today’s Bulgaria). In tracing the footsteps of İbrahim Temo and Mustafa Ragıp, two self-exiled figures from İstanbul, this study captures a particular moment when the Danubian cities became the hotbed of transnational radicalism, as a number of assassination plots began to be hatched by Muslim revolutionaries. A well-connected port city serviced by regular steamship links, Rusçuk was where professional revolutionaries met with the local Muslims, much to the ire of Ottoman diplomats in the region. In capturing their encounters, the goal is to point to the significance of Young Turk activities in the Balkans before the turn of the century, a phase which remains understudied in the existing literature. By focusing on a secondary port city that became home to failed assassination plots, this article also seeks to contribute to ongoing discussion in global history that warns against narratives of unhindered globalization. In studying fin-de-siecle radicalization, I hope to contribute to these debates by reflecting upon the limits of globalization as a productive field of historical inquiry.
