Hungarian maps based on the Gesta Hungarorum call it Kazárország which according to Simon of Keza was ruled by Zvataplug son of Morout, a Prince of Poland who had subdued Bractari and ruled as Emperor of the Bulgars and Moravians. Prince Morout occupied Crișana and the people that are called Cozar inhabited that land. Prince Morout's son Zvataplug appears to have been the father of Prince Morout's grandson Menumorout (Stallion of Morout) who succeeded Zvataplug and wed his daughter to Árpád's son Zoltán of Hungary father of Taksony of Hungary.
