Tögs-Ochiryn Namnansüren was a Mongolian revolutionary and Prime Minister on two separate occasions. He was a powerful hereditary prince and a prominent Mongolian independence leader who served as the first prime minister as Autonomous Mongolia from 1912 to 1915. He could allegedly trace his heritage back to Genghis Khan. In 1911, Namnansüren persuaded Mongolia's religious leader Bogd Khan to call a congress of Mongolian princes and high-ranking lamas in Khüree to initiate independence from China. As a part of a delegation to seek support from European powers, Namnansüren was sent to St Petersburg by Bogd Khaan. Other members of the Bogd Khaan's government included the Da Lam Tserenchimed (minister for internal affairs), Mijiddorjiin Khanddorj, Dalai-Van Gombosuren, Dambyn Chagdarjav, and Erdene Van Namsrai.
From November 1913 to January 1914 Namnansüren lead another delegation to St Petersburg, this time representing Mongolian interest in redrawing the border between Siberia and Manchuria. Mongolian hopes for international recognition of its independence and support for a union between Inner and Outer Mongolia were ultimately dashed when the agreement re-confirmed the country’s status as an autonomous region within China. Having failed to obtain any of his objectives, Namnansüren found his political influence to have diminished upon his return to Mongolia in 1914. In 1915 the office of Prime Minister was abolished and Namnansüren was appointed minister of war.
Running under the Conservative Party, Namnansüren entered the race for prime minister in 1931, hoping to regain his political status. He won the election, becoming the first Conservative prime minister in Mongolian history. He oversaw parts of the Mongolian Revolution in which Mongolia and China were at war, with the Mongolian imperialist dream of annexing the inner regions. He also oversaw parts of the Pacific War, and helped in the annexation movement of Manchuria and helped send Mongol troops to eastern and northern China. He also pledged support to Russia and Alash during the Xinjiang War, and recognized the First East Turkestan Republic as an independent state from China. His Conservative policies received mixed views from the population; and leftists viewed him as a supporter of Bogd Khaan. His policies weren't too harsh like those of Bogd, however non-Buddhists didn't have the nicest feelings towards him.
