When the Russian Politburo published a decree guaranteeing Buryat autonomy from Russia, Elbegdorj stressed it as something with "great significance to Mongolia".
He also accompanied delegates Soliin Danzan and Dambyn Chagdarjav to Moscow where they met Russian communist leader Nikolay Bukharin.
By this time he was recognized as one of the leading figures of Mongolia's revolutionary government[8] and with the backing he enjoyed from Moscow, he came to dominate the political scene in Ulan Bator, often emerging as victor from party infighting.
[9] In 1922 he successfully collaborated with Soliin Danzan and Damdin Sükhbaatar to eliminate Prime Minister Dogsomyn Bodoo in a power struggle.
Recognized as leader of the party's leftist faction, Elbegdorj joined with rightists under Tseren-Ochiryn Dambadorj to orchestrate Danzan's the arrest and execution.
[11] Within a day Danzan and several colleagues were arrested and executed, sending a shock wave through the party that solidified Soviet dominance of Mongolian politics.
Under no circumstances are we going to surrender this weapon into the hands of Mongol feudal lords, Japanese militarists, and Russian bandits like Baron Ungern.
"[6]: 114 By 1925, Elbegdorj was accused of being a bourgeois nationalist and a Pan-Mongolist[14] whose pan-Mongolian sentiments, expressed at the Third Party Congress in 1924, were seen as contrary to communist policy.
He then worked at NIANKP (Scientific-Investigative Association for National and Colonial Problems) and taught at the Communist University of the Toilers of the East training many of the young MPRP members who attended the school.
