active only in the area included in the rebellion against Frankish rule, that is, only west of the Una river. It is possible that Borna was the duke of an archonty not yet part of Croatia in the beginning of the 9th century, neither was Croatia at all included in the events of Ljudevit's rebellion. The war was fought only in the area under Frankish rule, while Dalmatian Croatia was outside those events, as it at that time was under Byzantine supreme rule. M. Atlagić and B. Milutinović (2002) treat him as a Dalmatian Slavic ruler. Another view is that it seems that after the Timociani did not receive aid, a part of them settled in Slavonia, it seems also that Borna moved with them; S. Prvanović (1962) viewed him as a duke from Timok-Kučevo that founded the first Croatian state, while M. S. Milojević (1872) treated him as a Frankish vassal in "Littoral Croatia" that originally held three counties in the Timok region. Prvanović claimed that F. Racki had falsified the RFA, that Borna actually was the duke of Guduscani and Timociani, combined, and that Racki had put a comma after Guduscani, based on the identification with Gacka in Lika and presumption that due to the geographical distance between the two meant that the two could not have had nearer contact nor a joint duke. Prvanović was not the first to put the Guduscani in the Timok region; 19th-century P. J. Šafárik and V. Karić located them around the Timok and Danube. Fine Jr. first (1983, 1991) called him a ruler of "Dalmatian Croatia", in c. 810–821, having succeeded Višeslav and "who resided at Nin and seems to have been the ruler of most of the Croatians in northern Dalmatia, was also a Frankish Vassal." then (2010) called him simply a Slavic prince, and also noted that the Franks did not use the term "Croats", suggesting that those usually called Croats in scholarship did not actually use that name. B. W. Scholz (1970) uses the original titles found in the primary source, and in the index uses "duke of Dalmatia". R. McKitterick (1983) called him a "leader of the Dalmatian Croats". C. R. Bowlus (1995) treated him as the "dux of the Guduscani and Timocian Slavs" and a "Dalmatian prince". F. Curta (2006) treats him as a Slavic ruler, of the Guduscani, a Slavic tribe in the Gacka region
