According to research by Sedov, all early mentions of Croatian ethnonym are in the areas where ceramics of Prague-Penkovka culture were found. It originated in the area between Dniester and Dnieper, and later expanded to the West and South, and its bearers were the Antes tribes. A. V. Majorov criticized Sedov's consideration, who almost exclusively related the Croats with Penkovka culture and the Antes, because the territory the Croats inhabited in the middle and upper Dniester and the upper Vistula was part of Prague-Korchak culture related to Sclaveni which was characteristic for the Kurgan-type of burial which was also found in the upper Elbe territory where presumably lived the Czech Croats. They were representatives of both these archaeological cultures and possibly formed before them at the least late 4th or during the 5th century in the area of the intertwining of these cultures around the Dniester basin. It is considered that the Carpathian Croats later between 7th and 10th century were part of the Luka-Raikovets culture, which developed from Prague-Korchak culture, and was characteristic for East Slavic tribes, besides Croats, including Buzhans, Drevlians, Polans, Tivertsi, Ulichs and Volhynians.
