During the nineteenth century―as violence, population dislocations, and rebellions unfolded in the borderlands between the Russian and Ottoman Empires―European and Russian diplomats debated the “Eastern Question,” or, “What should be done about the Ottoman Empire?” Russian-Ottoman Borderlands brings together an international group of scholars to show that the Eastern Question was not just one but many questions that varied tremendously from one historical actor and moment to the next. The Eastern Question (or, from the Ottoman perspective, the Western Question) became the predominant subject of international affairs until the end of the First World War. Its legacy continues to resonate in the Balkans, the Black Sea region, and the Caucasus today. The contributors address ethnicity, religion, popular attitudes, violence, dislocation and mass migration, economic rivalry, and great-power diplomacy. Through a variety of fresh approaches, they examine the consequences of the Eastern Question in the lives of those peoples it most affected, the millions living in the Russian and Ottoman Empires and the borderlands in between.
