Dušan, who had himself crowned as "Emperor of Serbs and Greeks," made both Serbian and Greek the official languages of his empire, wrote charters and signed in Greek, and adopted Eastern Roman law as the foundations of his empire.
Dušan, som själv krönte sig till "kejsaren av serber och greker," gjorde både serbiska och grekiska till officiella språk i sitt imperium, skrev stadgar och undertecknade på grekiska och antog östromerska lagar som grunden till sitt imperium.
