In 221 BCE the state of Qin vanquished its rivals and established the first empire on Chinese soil, starting a millennium—long imperial age in Chinese history. Hailed by some and maligned by many, Qin has long been an enigma. In this pathbreaking study, the authors integrate textual sources with newly available archeological and paleographic materials, providing a boldly novel picture of Qin’s cultural and political trajectory, its evolving institutions and its religion, its place in China’s history, and the reasons for its success and for its ultimate collapse.
