A major new work in modern Tibetan history, this book follows the evolution of Tibetan Buddhism's trulku (reincarnation) tradition from the seventeenth to the nineteenth centuries, along with the Emperor of China's efforts to control its development. By illuminating the political aspects of the trulku institution, Schwieger shapes a broader history of the relationship between the Dalai Lama and the Emperor of China, as well as a richer understanding of the Qing Dynasty as an Inner Asian empire, the modern fate of the Mongols, and current Sino-Tibetan relations. Unlike other pre-twentieth-century Tibetan histories, this volume rejects hagiographic texts in favor of diplomatic, legal, and social sources held in the private, monastic, and bureaucratic archives of old Tibet. This approach draws a unique portrait of Tibet's rule by reincarnation while shading in peripheral tensions in the Himalayas, eastern Tibet, and China. Its perspective fully captures the extent to which the emperors of China controlled the institution of the Dalai Lamas, making a groundbreaking contribution to the past and present history of East Asia.
