The Croats are a Balkanic people with a Slavic language.
The issue of their origin has been subject to hard debates, but their roots are still "officially" not known. This book offers
a new theory, well established in contrary to the others (the Iranic, Germanic, Slavic and Avaro-Bulgaric theories), about who the first Croats were, by explaining how a Turkic tribe disappeared in the north of the Caucasus and appeared in the south of Poland, and then migrated to Dalmatia to start the process of making of the Croatian nation. This study includes also many new ideas about Proto-Hungarian, Proto-Bulgarian, Proto-Serbian, as well as Bosnian and Khazarian histories.
