This chapter introduces the problem of studying the nomadic states of Inner Asia and specifically the Xiongnu state of the third century BC. Nomadic peoples in general have not been portrayed with much veracity in the historical record and ethnographic accounts, although detailed, mostly describe the conditions of mobile herders during the mid- to late
