This book describes the significant changes which occurred in the Central Asian Steppe from the mid-eighteenth to the early twentieth century and which symbolize the “frontierization of Central Eurasia,” exploring the connections between these and the policy responses of the Qing dynasty. Through this research, readers can also clarify the correlation between Qing policy developments and the reorganization of order in the Central Asian Steppe, as well as gain a better understanding of the Qing’s empire-building from the perspective of innermost Eurasia.
