Book excerpt: Chieftains, Lamas, and Warriors: A History of Kham 1904–1961 explores the region of Kham, situated between Central Tibet and China. By highlighting Kham’s pivotal role in Sino-Tibetan relations and frontier dynamics, this book challenges the traditional focus of scholarly research that treat Kham as a mere transit point. Yudru Tsomu argues for the significance of frontier regions in shaping historical narratives and power structures. Tsomu explores how Kham forged its own identity amidst the assimilation pressures exerted by Central Tibet and China. Supported by a wealth of original sources in Chinese, Tibetan, and Western languages—including previously untapped personal and archival collections in China—this book offers a compelling reassessment of Kham’s historical agency and significance.
