"Natur and development of events, supported by clear linguistic proofs, lead to the assessment that the Croats of the Central Europe, the "White Croats", were from the Ogur group of Turks, and were brothers of the Danubian, Volga and Caucasus Bulgars. They came to Galicia, the heartland of Slavs in the mid 6th century, after being expelled by the Avars, as above said; so were not yet, or at all slavicized in the time of Herakleios. They everywhere organized the local people, overwhelmingly Slavs, to resist the Avar invasion. A group of them, led by seven brothers, whose names we know and are all Turkic, left the country to move Dalmatia, as allies of Byzantium, which was likewise in an endless conflict with the Avars. Interesting enough, seven brothers of Porphyrogenitus and 'Belye Ugry' (White Ogurs) of the Russian chronicle Povest' did the same thing in the time of Herakleios. In their new country, in spite of the very scarcity of sources, we find Turkic-named governors among Croats in the first generations, but later they disappear and the people became purely Slavic [...]. The Croatian case is basically a copy of the Danubian Bulgar one. Thanks to the Byzantine neighborhood we know well about the latter. Early Croatian history faces a serious lack of material sources, but even those one present enough proof to think that the nation and the state founders of Croats were of Turkic origin."

"Briefly, the word "greater" for the Northern Croatia belong to the Post-Hunnic, Oguro-Bulgaric world in particular, and to the Eurasian traditions in general." (Osman Karatay, In search of the lost tribe: the origins and making of the Croatian nation, Ayse Demiral, 2003, pp. 69)
"[...] personal names are either substantial words, not changing so easily, except dialectical differences, or explainable in basic linguistic terms, as the seven Croat names can be easily etymologized in Turkic." (Osman Karatay, In search of the lost tribe: the origins and making of the Croatian nation, Ayse Demiral, 2003, p.95)
Über den türkischen Ursprung einiger Serben und der ersten serbischen Herrscher:
"Therefore, we can conclude that there was more or only Turkic names among the first Serbian princes." (Osman Karatay, In search of the lost tribe: the origins and making of the Croatian nation, Ayse Demiral, 2003, p.110)
"Serbian and Bulgar rulers were cousins of each other; and the Croatian ruling strata, which expressed its sincere feelings towards their direct relatives Hungarians (Onogurs), was also conscious of the political and partly ethnic kinship with the Serbian and Bulgar courts, or hordes." (Osman Karatay, In search of the lost tribe: the origins and making of the Croatian nation, Ayse Demiral, 2003, p.110)
"We can find some Turkic names among the leaders of the later Serbs." (Osman Karatay, In search of the lost tribe: the origins and making of the Croatian nation, Ayse Demiral, 2003, p.109)
"He and his followers fled to Southern Macedonia, then turned back and settled on the heart of today's Serbia. Kuber was likely the first Serbian prince. There are a few Turkic names among the first Serbian governors. Around this politial formation, the process of making of the Serbian nation developed." (Osman Karatay, In search of the lost tribe: the origins and making of the Croatian nation, Ayse Demiral, 2003, p.148)
"[...] sources clearly show presence of an Oguro-Bulgaric finger in the beginnging of the Serbian state [...]." (Osman Karatay, In search of the lost tribe: the origins and making of the Croatian nation, Ayse Demiral, 2003, p.8)
