Dr. Bryan K. Miller, UMMAA curator of Asian archaeology, recently saw the release of his book, Xiongnu: The World's First Nomadic Empire, by Oxford University Press.

Miller presents a more complex and nuanced narrative of how an empire based firmly in the steppe over two thousand years ago managed to formulate a robust political economy and a complex political matrix that capitalized on mobilities and alternative forms of political participation and allowed the Xiongnu to dominate vast realms of central Eurasia and leave lasting geopolitical effects on the many worlds around them.
