With the fall of the Qing dynasty in 1911, Mongolia under the Bogd Khaan declared its independence. But the newly established Republic of China considered Mongolia to be part of its own territory. Yuan Shikai, the President of the Republic of China, considered the new republic to be the successor of the Qing. Bogd Khaan said that both Mongolia and China had been administered by the Manchu during the Qing, and after the fall of the Qing dynasty in 1911, the contract of Mongolian submission to the Manchu had become invalid.
