The leaders of the East Urga group were Soliin Danzan (1885–1924), an official in the Ministry of Finance, and Dansranbilegiin Dogsom (1884–1939), an official in the Ministry of the Army. Another, albeit less prominent at the time, member was Damdin Sükhbaatar (1893–1923), a soldier in the Mongolian army who, after his death, was canonised by Communist historians as the "Lenin of Mongolia". The beginning of the East Urga group may be traced to mid-November 1919, when several of the more militant members of the lower house of the Mongolian Parliament, including Danzan and Dogson, met secretly on the first night following its dissolution by Xu Shuzheng, and resolved to resist the Chinese. Twice they approached the Bogd Khan to obtain his support for armed resistance; twice the Khan counselled patience. The group plotted to seize the Mongolian army's arsenal and assassinate Xu Shuzheng; however, the placement of Chinese guards at the arsenal and a revised travel itinerary for Xu thwarted both plans.
