Book excerpt: Three of the formative revolutions that shook the early twentieth-century world occurred almost simultaneously in regions bordering each other. Though the Russian, Iranian, and Young Turk Revolutions all exploded between 1904 and 1911, they have never been studied through their linkages until now. Roving Revolutionaries probes the interconnected aspects of these three revolutions through the involvement of Armenian revolutionaries whose movements and participation within these empires (where Armenians were minorities) and across frontiers tell us a great deal about the global transformations that were taking shape. Exploring the geographical and ideological boundary crossings that occurred, Houri Berberian’s archivally grounded analysis of the circulation of revolutionaries, ideas, and print tells the story of peoples and ideologies amid upheaval and collaboration. In doing so, it illuminates our understanding of revolutions and movements.
