It was thought that the same kind of military organization was used by the Magyars during the conquest of Hungary. According to Ahmad ibn Rustah (c. 930), a Persian explorer and geographer relying on second-hand information, the "Magyars are a race of Turks and their king rides out with horsemen to the number of 10,000 and this king is called Kanda". However, the Magyars were linguistically Finno-Ugric-speaking peoples and did not speak Turkic. Modern scholarship finds that the Magyar/Hungarian cavalry units were called "banderia" and "dundar" and not organized in units of 10,000.
