erned a vast and culturally diverse territory, encompassing a wide range of local political systems and regional elites. But the Qing empire was built and held together by a single imperial elite: the more than two million members of the hereditary Eight Banner system who were at the core of both the military and the bureaucracy. The banner population was multiethnic, linked by shared membership in a clearly demarcated status group defined in law and administrative practice. Banner people were bound to the court by an exchange of loyal service for institutionalized privilege, a relationship symbolically conceptualized as one of slave to master.

Slaves of the Emperor explores the Qing approach to one of the fundamental challenges of early modern state-building: how to develop an effective bureaucracy with increasing administrative capacity to govern a growing polity while retaining the loyalty of the ruling family's most important supporters. David C. Porter traces how the banner system created a service elite through its processes of incorporating new members, its employment of bannermen as technical specialists, its imposition of service obligations on women as well as men, and its response to fiscal and ideological challenges. Placing Qing practices in comparative perspective, he uncovers crucial parallels to similar institutions in Tokugawa Japan, imperial Russia, and the Ottoman Empire. Slaves of the Emperor provides a new framework for understanding the structure and function of elites both in China and across Eurasia in the early modern period.
