Bulgarian literature is literature written by Bulgarians or residents of Bulgaria, or written in the Bulgarian language; usually the latter is the defining feature. Bulgarian literature can be said to be one of the oldest among the Slavic peoples, having its roots during the late 9th century and the times of Simeon I of the First Bulgarian Empire. Notable modern Bulgarian works of literature are The Peach Thief by Emiliyan Stanev, September by Geo Milev, Under The Yoke by Ivan Vazov, The Windmill by Elin Pelin, and Depths by Dora Gabe. The book Wild Stories (Divi Razkazi/Диви разкази) by Nikolay Haytov is included in the UNESCO Historical Collection. Middle Ages With the Bulgarian Empire welcoming the disciples of Cyril and Methodius after they were expelled from Great Moravia, the country became a centre of rich literary activity during what is known as the Golden Age of medieval Bulgarian culture. In the late 9th, the 10th and early 11th century literature in Bulgaria prospered, with many books being translated from Byzantine Greek, but also new works being created. Many scholars worked in the Preslav and Ohrid Literary Schools, creating the Cyrillic script for their needs. Chernorizets Hrabar wrote his popular work An Account of Letters, Clement of Ohrid worked on translations from Greek and is credited with several important religious books, John Exarch wrote his Shestodnev and translated On Orthodox Christianity by John of Damascus, Naum of Preslav also had a significant contribution. Bulgarian scholars and works influenced most of the Slavic world, spreading Old Church Slavonic, the Cyrillic and the Glagolithic alphabet to Kievan Rus', medieval Serbia and medieval Croatia. As the Bulgarian Empire was subjugated by the Byzantines in 1018, Bulgarian literary activity declined. However, after the establishment of the Second Bulgarian Empire followed another period of upsurge during the time of Patriarch Evtimiy in the 14th century. Evtimiy founded the Tarnovo Literary School that significantly affected the literature of Serbia and Muscovite Russia, as many writers fled abroad after the Ottoman conquest. Apart from Evtimiy, other established writers from the period were Constantine of Kostenets (1380-first half of the 15th century) and Gregory Tsamblak (1365–1420). Medieval Bulgarian literature was dominated by religious themes, most works being hymns, treatises, religious miscellanies, apocrypha and hagiographies, most often heroic and instructive. Early Ottoman rule The fall of the Second Bulgarian Empire to the Ottomans in 1396 was a serious blow for
