Abstract: This article utilizes a wide array of historical documents to present a detailed and systematic discussion of the political activities of Zhangjia Ruobiduoji, an imperial tutor in the Qing dynasty. As a political and Tibetan Buddhist leader for nearly half a century, Zhangjia contributed to resolving many diverse ethnic and religious issues. He made positive and worthwhile contributions to the reinforcement and development of a united and multinational China in the early stages of the Qing Dynasty. The article also addresses inaccurate scholarly criticisms of Zhangjia Ruobiduoji.
