This programme, set up in 1981, aims to explor Byzantium's relations with the world of the Slavs and the Balkans. The researchers who have worked at times on programme have focused their interests on the following areas: Byzantium's political, commercial and cultural relations with the neighboring peoples of the Balkans, the geography and social movements of the Balkans, and, lastly, guides to the bibliography relevant to the Slavic world and its dealings with Byzantium. The programme has developed strong ties with the Serbian Academy of Arts and Sciences, the Bulgarian Academy of Sciences, the Roumanian Institut des études Sud-Est Européennes, the Russian Academy of Sciences and the French Centre National des Recherches Scientifiques.
