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, although there were stirrings in the 18th century. Russia, as fellow Orthodox Slavs, could appeal to the Bulgarians in a way that Austria could not. The Treaty of Küçük Kaynarca of 1774 gave Russia the right to interfere in Ottoman affairs to protect the Sultan's Christian subjects.
The Bulgarian national revival started with the work of Saint Paisius of Hilendar, who opposed Greek domination of Bulgaria's culture and religion. His work Istoriya Slavyanobolgarskaya ("History of the Slav-Bulgarians"), which appeared in 1762, was the first work of Bulgarian historiography. It is considered Paisius' greatest work and one of the greatest pieces of Bulgarian literature. In it, Paisius interpreted Bulgarian medieval history with the goal of reviving the spirit of his nation.
His successor was Saint Sophronius of Vratsa, who started the struggle for an independent Bulgarian church.
The first nationwide movement was for enlightenment. Educated Bulgarians started to finance the building of Bulgarian schools. In spite of Ottoman resistance, Bulgarians founded their own schools and started publishing textbooks. The Greek revolt against the Ottomans in 1821 also influenced the small Bulgarian educated class. But Greek influence was limited by the general Bulgarian resentment of Greek control of the Orthodox Church in Bulgaria. It was the struggle to revive an independent Bulgarian church which first roused Bulgarian nationalist sentiment. When some Bulgarians threatened to abandon the Orthodox Church altogether and form a Bulgarian Uniate church loyal to Rome, Russia intervened with the Sultan. In 1870 a Bulgarian Exarchate was created by an edict of the Sultan, and the first Bulgarian Exarch (Antim I) became the natural leader of the emerging nation. The Patriarch of Constantinople responded by excommunicating the Bulgarian Exarchate, which reinforced their will for independence.
