Damdinbazar supported Mongolian independence as early as 1900 during the military rebellion in
Uliastai. From 1911 to 1912 he publicly campaigned for Mongolia's independence from Chinese rule. He was appointed Minister for the Pacification of the Western Border Areas during the
Bogd Khanate and together with
Khatanbaatar Magsarjav,
Manlaibaatar Damdinsüren,
Togtokh Taij, and
Ja Lama took part in the liberation of
Khovd. In recognition of his leadership he was awarded the honorable title
Samadi Nomun Khan in 1912. As a representative of the
Bogd Khan's government, he traveled several times to
Beijing to voice Mongolian concerns and demands. He was part of a delegation in 1919 that established contact with the American consul in
Kalgan with a letter from the
Bogd Khan inviting the U.S. to open a consulate in the newly renamed Mongolian capital Niislel Khüree. After the Chinese occupied Niislel Khüree in 1919, Damdinbazar became an official under the Chinese minister Chen Yi while the Bogd Khan was placed under house arrest. He then served as prime minister and minister of the interior in the Mongolian government established by the Bogd Khan on 22 February 1921 after capture of Niislel Khuree by Roman von Ungern-Sternberg. Damdinbazar ignored approaches made to him by Mongolian revolutionary forces in spring 1921 and withdrew from public service after Baron Ungern was defeated by the Soviet Red Army and Mongolian revolutionary forces under
Damdin Sükhbaatar in July 1921. Later that year, however, he was contacted by
Comintern agents and agreed to oppose
White movement forces in Western Mongolia. He then joined forces with
Khatanbaatar Magsarjav in Uliastai in the campaign against the Whites. ==Prime minister==
