The Tarnovo Literary School (Bulgarian: Търновска книжовна школа) of the late 14th and 15th century was a major medieval Bulgarian cultural academy with important contribution to the Medieval Bulgarian literature established in the capital of Bulgaria Tarnovo. It was part of the Tarnovo School of Art which was characteristic for the culture of the Second Bulgarian Empire.
With the orthographic reform of Saint Evtimiy of Tarnovo and prominent representatives such as Gregory Tsamblak or Constantine of Kostenets the school influenced Russian, Serbian, Wallachian and Moldavian medieval culture. That is famous in Russia as the second South-Slavic influence.
The main prerequisite for the Tarnovo Literary School was the cultural revival of the late 14th century. It was largely due to the interest of Emperor Ivan Alexander (1331–1371) in literature and art and the traditions that he left to his sons and successors Ivan Shishman and Ivan Stratsimir in that direction. Patriarch Theodosius of Tarnovo also had some credit to the establishment of the School.
The school was established in the capital of the Bulgarian Empire Tarnovo by Saint Evtimiy of Tarnovo. It established his orthographic and linguistic reform rules of the Bulgarian language and wrongly translated texts were corrected, becoming models for the Orthodox churches of Bulgaria, Serbia, Wallachia, Moldavia and Russia that also used the Church Slavonic language.
