 The root of such indigenous mixture of Illyrism and Pan-Slavism can be seen in "Concise history of the Slav Bulgarian People" (1792), written by Spyridon Gabrovski, whose original manuscript was found in 1868 by the Russian scientist Alexander Hilferding on his journey in Macedonia.Gabrovski tried to establish a link between the Bulgaro-Macedonians from one side, and the Illyrians and the ancient Macedonians from another, who he regarded also "Slavs".The main agenda of this story about the mythical "Bulgaro-Illyro-Macedonians" was to assert that the Macedonian and Bulgarian Slavs were among the indigenous inhabitants of the Balkans.
