In April 1876 a Bulgarian rising was crushed by Ottoman regular and irregular forces. The Bulgarian News Agency's account records that estimates of Bulgarian deaths range from the 12,000 reported by the British diplomat Walter Baring and the 15,000 reported by the American consul Eugene Schuyler to later nineteenth-century figures of 25,000-40,000, with modern scholarship generally accepting 15,000-30,000; eighty settlements were burned, two hundred more sacked, and around 10,000 Bulgarians imprisoned. Gladstone's pamphlet on the 'Bulgarian horrors' and the European press campaign that followed made intervention politically possible, and Russia declared war in April 1877. The Russian advance and the establishment of Bulgaria, and the enlargement of Serbia and Montenegro, then produced the largest single displacement in Ottoman history: on Nedim Ipek's count the empire was hosting 1,230,000 Balkan Muslim refugees by 1879. Refugee property left behind was appropriated under land laws that the new Balkan states inherited from the Ottoman code of 1858.
Ottoman irregulars suppressed the Bulgarian April Uprising of 1876, and the Russian invasion and the creation of Bulgaria, Serbia, Montenegro and Romania then drove the Muslim population of the Balkans into the Ottoman Empire
Justin McCarthy's reconstruction from Ottoman population registers (nüfus defterleri) puts the Muslim population of the Danube and Edirne provinces at roughly 1.5 million before the war; Bulgarian and Russian sources give lower Muslim shares and higher Christian ones, and the ethnic arithmetic of these registers is contested on all sides. The figure should be read as an order of magnitude within a disputed range.
The range covers two different bodies of dead. The lower figure is the modern consensus range of 15,000-30,000 Bulgarian civilians killed in the suppression of the April Uprising in 1876, reported by BTA and derived from the Baring and Schuyler consular investigations against the much lower Ottoman inquiry figures. The upper figure reflects estimates of Muslim civilian deaths during and after the war of 1877-78, of which the best known is Justin McCarthy's calculation of roughly 260,000 dead among the Muslim population of Bulgaria, arrived at by comparing Ottoman population registers with post-war Bulgarian censuses; McCarthy's method and his conclusions are disputed by other historians of the period. Deaths in flight from disease, cold and hunger dominate the upper figure.
BTA's account, drawing on the Baring and Schuyler investigations and on later scholarship, documents the burning of eighty settlements and sacking of two hundred more, killings of civilians, rape, looting and the imprisonment of some 10,000 Bulgarians in 1876; comparable acts against Muslim villagers during the Russian advance are documented in the Ottoman refugee commission records used by Hamed-Troyansky.
