Sources on Medieval Croatia

Early medieval Croatian history fits the concluding line to the old jingle: the more you study the less you know. When I was and undergraduate studying Balkan history I thought I knew quite a bit about Croatia; but as I study more about Croatia, one by one ""facts"" that I knew before turn out to be dubious, based on questionable sources or no sources at all. Most of the existing literature in western languages on medieval Croatia is extremely poor; and frequently it is marred by nationalistic bias.

Much of the information about medieval Croatian history comes from later (seveneenth- and eigteenth-century) narrative histories. These were written by enthusiastic people but ciontain a mixture of fact and legend; and since many of the documents they based their works on are now lost, it is extremely difficult to judge wheter their information came from reliable source or not.

One of Ladislaus's most significant achievements was the occupation of Hungary's southern neighbour, Croatia. ... The small kngdom, born in the tenth century, streched from the Kapela mountains to the Adriatic sea, its center being Biograd, located on the coast.

King Demetrius Zvonimir, who, not being a member of the ruling dynasty, obtained his throne throug election, asked Pope Gregory VII fo a crown in 1075, and, in return, declared his kingdom as a papal fief. After his death, Ladislaus laid claim on his realm by the right of his sister, Zvonimir's widow, and had no difficulty in taking possession of Croatia in 1091. He bestowed the new kingdom, together with royal title, on his nephew, Almos, son of Geza I ...

I further entertained myself reading yet another great discoveries of contemporary Croatian historians (soc.culture.yugoslavia) ....

The exclusive revelation is the result of ""scientific"" research by Croatian historian Dragutin Pavlicevic, and found its place in history books. The Split newspaper ""Feral Tribune"" reveals that Pavlicevic authored a chapter entitled ""Croatian Indians"", included in the second grade history textbook, shedding new light on the history of native Americans and their ties with Croats, ""one of the oldest nations in Europe"". He affirms that in North Carolina ""a tribe has been living for more than 4 centuries differing in the color of skin, hair and facial features from other tribes"". According to the same historian this is not surprising because the members of these tribe ""have the noble blood of ancient Croats from Dubrovnik in their veins"". Mr. Pavlicevic also speaks about the Mateo Indians, named after their ancestor Mateo - a Croat named Mate. ""In his work, Dragutin Pavlicevic stresses that he estimates that presently there are more than 2 million Croatian descendants throughout the United States"", states the Split newspaper.

A theory that Croatian sailors, in the service of the Moorish caliphs, probably reached the coasts of the Americas not only before Columbus, but also before the Vikings themselves, may be corroborated by exceptiona
