 Slavic culture was centred in both the First and Second Bulgarian Empires during much of the Middle Ages. The Preslav, Ohrid and Tarnovo literary schools exerted considerable cultural influence over the Eastern Orthodox world. Many languages in Eastern Europe and Asia use Cyrillic script, which originated in the Preslav Literary School around the 9th century. The medieval advancement in the arts and letters ended with the Ottoman conquest when many masterpieces were destroyed, and artistic activities did not re-emerge until the National Revival in the 19th century. After the Liberation, Bulgarian literature quickly adopted European literary styles such as Romanticism and Symbolism. Since the beginning of the 20th century, several Bulgarian authors, such as Ivan Vazov, Pencho Slaveykov, Peyo Yavorov, Yordan Radichkov and Tzvetan Todorov have gained prominence. In 1981 Bulgarian-born writer Elias Canetti was awarded the Nobel Prize in Literature.
