Collective monograph "Russia: a look at the Balkans. XVIII-XXI centuries To the 100th anniversary of the birth of I.S. Dostyan" was prepared by employees of the Institute of Slavic Studies of the Russian Academy of Sciences and other scientific and educational institutions of Russia and Bulgaria on the basis of materials from a scientific conference within the framework of the X Nikitin readings held in December 2020 in Moscow. They were timed to coincide with the 100th anniversary of the birth of the outstanding Russian Slavist and Balkanist Irina Stepanovna Dostyan (1920-2012). The essays included in the monograph cover various aspects of the development of Russian-Balkan relations over more than three centuries and are based on unpublished archival documents.
