BC formed a tribal league that was able to dominate much of Central Asia for more than 500 years. A number of Hsiung-nu customs do suggest Turkish affinities, which has led some historican to suggest that the western Hsiung-nu may have been the ancestors of the European Turks of later centuries. Others believe that the Hsiung-nu are the Huns, who invaded the Roman Empire in the 5th century)
