Tensions within the Ottoman Empire's Balkan territories had been building through economic strain, religious conflict, and nationalist movements among subject peoples. An Ottoman sovereign default declared on 30 October 1875, known in Turkish historiography as the Ramazan Kararnamesi, compounded existing grievances and weakened imperial authority in the region.
Beginning in July 1875, the Great Eastern Crisis unfolded as a succession of uprisings and wars across the Balkan Peninsula within Ottoman-administered territories. The crisis drew in multiple international powers, escalating from local revolts into a broader conflict that included the Russo-Turkish War of 1877–1878, known in Turkish as the 93 Harbi.
The crisis was formally concluded by the Treaty of Berlin in July 1878, which redrew boundaries across the Balkans and significantly reduced Ottoman territorial control in Europe. The settlement reconfigured the political order of southeastern Europe, affirming the growing influence of major European powers in resolving Ottoman imperial affairs.
