National Awakening

Bulgarian nationalism emerged in the early 19th century under the influence of western ideas such as liberalism and nationalism, which trickled into the country after the French Revolution, mostly via Greece. The Greek revolt against the Ottomans which began in 1821 (see History of Ottoman Greece), also influenced the small Bulgarian educated class. But Greek influence was limited by the general Bulgarian resentment of Greek control of the Bulgarian Church, and it was the struggle to revive an independent Bulgarian Church which first roused Bulgarian nationalist sentiment. In 1870 a Bulgarian Exarchate was created by a Sultan edict, and the first Bulgarian Exarch (Antim I) became the natural leader of the emerging nation. The Constantinople Patriarch reacted by excommunicating the Bulgarian Exarchate, which reinforced their will for independence.
In April 1876 the Bulgarians revolted in the so-called April Uprising. The revolt was poorly organized and started before the planned date. It was largely confined to the region of Plovdiv, though certain districts in northern Bulgaria, in Macedonia and in the area of Sliven also took part in it. The uprising was crushed with cruelty by the Ottomans who also brought irregular Ottoman troops (bashi-bazouks) from outside the area. Countless villages were pillages and tens of thousands of people were massacred, the majority of them in the insurgents towns of Batak, Perushtitsa and Bratsigovo in the area of Plovdiv. The massacres aroused a broad public reaction led by liberal Europeans such as William Gladstone, who launched a campaign against the "Bulgarian Horrors". The campaign was supported by a number of European intellectuals and public figures. 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.
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 Coalition was able to inflict a decisive defeat on the Ottomans at the Battle of Shipka and at the Pleven, and, by January 1878 they had liberated much of the Bulgarian lands.
