Soliin Danzan (1885 - 1924) was a Mongolian revolutionary and chairman of the Central Committee of the Mongolian People's Revolutionary Party. Danzan was working as a customs official when he founded one of the two groups that would later unite to form the MPRP in 1919; after the lower house of parliament was dissolved. He was known as one of the First Seven leaders of the MPRP. According to historian Shagdariin Sandag; Danzan espoused a general hope of uniting all people of Mongolian origin into one state; and in April 1922 made a speech at a party and Youth League meeting calling for all Mongols to unite; antagonizing the Soviets. Danzan had distanced himself further from Soviet policy when he called for a significant reduction in the number of Soviet advisors in Mongolia. Subsequently Danzan was among the leaders executed by Comintern in massacres carried out in collaboration with the Soviet secret services. According to Sandag; the execution of Danzan was a shock and served as a signal that confirmed the power of the Soviets in Mongolia.
