"The Realm of the Slavs", written by Ragusian historian Mavro Orbin (l. ca. 1550–1614), saw Emperor Dušan's actions and works positively. The book served as the primary source about early history of South Slavs at the time and most of the western historians drew their information on the Slavs from it. Early Serbian historians, even though they wrote according to the sources, were influenced by the ideas of the time they lived in. They made efforts to harmonize with two different traditions: one from brevets and public documents and other from genealogies and narrative writings. Of early historians, most information came from Jovan Rajić (1726–1801), who wrote fifty pages about Dušan's life. Rajić's work had great influence on Serbian culture of that time, and for decades it was the main source of information about Serbian history.
