thousand people were massacred, the majority of them in the insurgent towns of Batak, Perushtitza and Bratzigovo in the area of Plovdiv. The massacres aroused a broad public reaction led by liberal Europeans such as William Ewart Gladstone, who launched a campaign against the "Bulgarian Horrors". The campaign was supported by a number of European intellectuals and public figures, such as Charles Darwin, Oscar Wilde, Victor Hugo and Giuseppe Garibaldi. Conference of Constantinople The strongest reaction, however, came from Russia. The enormous public outcry which the April Uprising had caused in Europe gave the Russians a long-waited chance to realise their long-term objectives with regard to the Ottoman Empire. The Russian efforts, which were concentrated on ironing out the differences and contradictions between the Great Powers, eventually led to the Conference of Constantinople held in December 1876 – January 1877 in the Ottoman capital.

At the last minute, however, the Ottomans rejected the plan with the secret support of Britain. Russo-Turkish War, 1877–1878 Having its reputation at stake, Russia had no other choice but to declare war on the Ottomans in April 1877. The Romanian army and a small contingent of Bulgarian exiles also fought alongside the advancing Russians. The Russians and Romanians were able to inflict a decisive defeat on the Ottomans at the Battle of Shipka Pass and at the Pleven, and, by January 1878 they had occupied much of Bulgaria. They were thus able to dictate terms to the Sultan, and in the Treaty of San Stefano they proposed creating a large Bulgarian state, embracing almost all of the lands populated by Bulgarians. The Sultan was in no position to resist, but the other powers were not willing to
