Sebbirozi

• Russian historian Nikolay Karamzin identified them as the Severians.
• German historian Johann Caspar Zeuss believed them to have inhabited the hinterland of the Western Balkans.
• Polish historian Joachim Lelewel put them in Semberija.
• Slovak scholar Pavel Jozef Šafařík put them in Russia.
• Polish historian Henryk Łowmiański connected the ethnonym to the Severians.
• Polish historian Krzysztof Tomasz Witczak treats the Sebbirozi as one of the five Turkic tribes from the source, precisely the Sabirs. Already in 1958 Łowmiański considered etymological and geographical relation between the Sebbirozi, Attorozi, Uuillerozi, Zabrozi, Chozirozi due to unusual non-Slavic, yet Turkic suffix -rozi. The Attorozi themselves are described as populus ferocissimus.
