Abstract: Before 1911 Revolution, Gongsennorbo was famous for his great endeavors to introduce various self- strengthening measures to his jurisdiction. After the Wuchang Uprising in 1911, he refused to accept the newly founded Republic and planned to prevent the Qing’s rulership from collapse. When he returned to his jurisdiction, he attempted to seek the independence and autonomy of the Inner- Mongolia. After his plan was aborted, he went to Beijing and served as the president of the Mongolia- Tibet Bureau. Meanwhile, he joined the Revolutionary Alliance and was elected director for the Nationalist Party. Considering the complicated situations under which Gongsennorbo lived and his activities during the Republican Revolution, he still could be credited as the enlightened and reformist ethnic upper class, though his “reactionary” and “separatist”activities should he criticized.
