Kumans

Kumans, a historical people of Turki stock, who formerly occupied the South Russian steppes, but were driven west by the Mongols in the 13th century, when about 40,000 crossed the Carpathians and took refuge in Hungary. Here they occupied the two districts of Great and Little Rumania in the north-west, where they became completely assimilated to the Magyars. Those left behind in Russia were sold into bondage by the Mongols, and many of the Mamelukes, who became the virtual rulers of Egypt, were descended from these captives.
