This book is prepared primarily for students who are interested in studying the constitutional development and government structure of twentieth-century China. Since the emergence of the Chinese consti­ tutional movement at the end of the nineteenth century, political institutions in China have undergone constant changes. The first four chapters treat of constitutional development and government systems from the latter part of the Ch'ing dynasty to the re-unification of China by the Nationalist Party in 1928. The other eight chapters deal with the policies, programs, and institutions of the Nationalist and Commu­ nist governments up to 1962. While treatises on various subjects have been consulted, the sources of this book are chiefly based on the official documents from the collections as indicated in the bibliography. Materials in the first few chapters are partly drawn from my previous works on government and politics in China. Because of the immense scope of the subject and the intricacy of the problems involved, this work is not intended to be exhaustive, but is rather a brief description and discussion of each topic under consideration. As there are many valuable works on China in general as well as on her history and inter­ national relations, I have tried not to cover what has already been dealt with by others. In my presentation of facts and views, I have endeavored to be as objective as possible, personal political convictions notwithstanding.
