...the studies presented in this volume have...raised questions which need to be further explored...the level of scholarship expressed in this volume is very high. It is to the credit of the editors and each contributor that we can now say that the stage is set for a new understanding of this period in Chinese history. Harvard Journal of Asiatic Studies This volume presents a more authoritative, more comprehensive, and far clearer picture of these regimes that occupied first nothern and western China, an eventually the entire country, than has previously been available...It is difficult to do full justice in reviewing a volume of such magnitude...This volume is indeed a rich banquet, but it is also one that needs to be digested slowly in order to sample fully its varied flavors. Its publication is an event worthy of celebration. The Historian ...a tremendous contribution...this volume is an outstanding encyclopedic study of a unique part of Chinese history, and it should prove useful as a resource not only to researchers and graduate students, but also to those who teach undergraduates...unquestionably an important accomplishment. It will lead readers to a better understanding of the role of the non-Han peoples in Chinese history and encourage all to meditate upon the revolutionary question: what is, in fact, Chinese history? China Review International ...an important synthesis of aspects and periods of the history of China which have, until relatively recently, been somewhat neglected by scholars...Both editors and contributors deserve our congratulations and gratitude. D. O. Morgan, Reviews of Books ...an indispensable reference work. The International History Review ...a sound survey as well as an indispensable starting point for serious students or researchers.
