The Ottomans reorganised the Bulgarian territories, dividing them into several vilayets, each ruled by a Sanjakbey or Subasi accountable to the Beylerbey. Significant parts of the conquered land were parcelled out to the Sultan's followers, who held it as benefices or directly from him, or from the Beylerbeys. This category of land could not be sold or inherited, but reverted to the Sultan when the fiefholder died. The lands were organised as private possessions of the Sultan or Ottoman nobility, called "mülk", and also as an economic base for religious foundations, called vakιf, as well as other people. Bulgarians regularly paid multiple types of taxes, including a tithe, a capitation tax, a land tax, a levy on commerce, and also various irregularly collected taxes, products and corvees.
Religion
The Ottomans did not normally require the Christians to become Muslims. Nevertheless, there were many cases of individual or mass conversion, especially in the Rhodopes. According to Thomas Walker Arnold Islam was not spread by force in the areas under the control of the Ottoman Sultan. A 17th-century author said:
Meanwhile he wins by craft more than by force, and snatches away Christ by fraud out of the hearts of men. For the Turk, it is true, at the present time compels no country by violence to apostatise; but he uses other means whereby imperceptibly he roots out Christianity...
Non-Muslims did not serve in the Sultan's army. The exception to this were some groups of the population with specific statute, usually used for auxiliary or rear services, and the infamous blood tax, also known as devşirme, whereby every fifth young boy was taken to be trained as a warrior of the Empire. These boys went through harsh religious and military training that turned them into an elite corps subservient to the Sultan. These corps were called Janissaries and were an elite and loyal unit of the Ottoman army. Recruits were rarely gained through voluntarily accessions, as some parents were often eager to have their children enroll in the Janissary service that ensured them a successful career and comfort.
First revolts and the Great Powers
While the Ottomans were ascendant, there was overt opposition to their rule. The first revolt began at the time King Sigismund of Croatia and Hungary had established the chivalric Order of the Dragon, 1408, when two Bulgarian nobles, Konstantin and Fruzhin, liberated some regions for several years. The earliest evidence of continued local resistance dates from before 1450. Radik was recognised by the Ottomans as a voyvoda of the Sofia region in 1413, but later he turned against them and is regarded as the first hayduk in Bulgarian history. More than a century later, two Tarnovo uprisings occurred - in 1598 and 1686 around the old capital Tarnovo. Those were followed by the Catholic Chiprovtsi Uprising in 1688 and insurrection in Macedonia led by Karposh in 1689, both provoked by the Austrians as part of their long war with the Ottomans. All of the uprisings were unsuccessful and were drowned in blood. Most of them resulted in massive waves of exiles, often numbering hundreds of thousands. In 1739 the Treaty of Belgrade between Austrian empire and the Ottoman Empire ended Austrian interest in the Balkans for a century. But by the 18th century the rising power of Russia was making itself felt in the area. The Russians, as fellow Orthodox Slavs, could appeal to the Bulgarians in a way that the Austrians 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.
Bulgarian awakening
The Millet system was a set of confessional communities in the Ottoman Empire. It referred to the separate legal courts pertaining to "personal law" under which religious communities were allowed to rule themselves under their own system. The Sultan regarded the Ecumenical Patriarch of the Constantinople Patriarchate as the leader of the Orthodox Christian peoples of his empire. After the Ottoman Tanzimat reforms, Nationalism arose in the Empire and the term was used for legally protected religious minority groups, similar to the way other countries use the wordnation. New millets were created in 1860 and 1870 for Uniate and Orthodox Bulgarian Christian communities. In this way a separate Bulgarian diocese was established, based on ethnic identity rather than principles of Orthodoxy and territory. Armed resistance to the Ottoman rule escalated in the third quarter of the 19th century and reached its climax with the April Uprising of 1876 that covered part of the ethnically Bulgarian territories of the empire. The uprising, along with the strategic interests of Russia on the Balkans, was a reason for the Russo-Turkish War of 1877-1878 that ended with the establishment of an independent Bulgarian state in 1878, albeit far smaller than what Bulgarians had hoped for and what was originally proposed in the Treaty of San Stefano of 1878.
