The party previously followed Marxism-Leninism, a synthesis of the ideas of Karl Marx and Lenin introduced by Joseph Stalin in 1929, under which the industries of Mongolia were nationalized and a planned economy was implemented.However, the independence of the Bogd Khanate did not last since it was not recognized by its two neighbors (Russia and China) and was considered an autonomous region under Chinese sovereignty or suzerainty.During the occupation two groups, known as the Consular Hill (Konsulyn denj) and East Khuree (Züün khüree), formed as resistance movements.Livestock herds were forcibly collectivized, private trade and transport forbidden and monasteries and the nobility were attacked.With state-run trade and transport unable to function, Mongolia's economy broke down—over seven million head of livestock dead, leading to widespread unrest in 1932.The 11th party congress was held in December 1947, approving Mongolia's first five-year plan to intensify development of the economy, industry, animal husbandry and agriculture in stages.Tsedenbal purged his political rivals: Dashiin Damba in 1958–1959, Daramyn Tömör-Ochir in 1962, Luvsantserengiin Tsend in 1963 and the Lookhuuz-Nyambuu-Surmaajav anti-party group in December 1964.Tsedenbal's attempts to make Mongolia the 16th Republic of the Soviet Union met strong opposition from other politicians and he was accused of treachery.In August 1984, Yumjaagiin Tsedenbal was forced into retirement in a Soviet-sponsored move, allegedly due to age and mental state.[6] Over the next few months, the demonstration organizers founded Mongoliin Ardchilsan Kholboo (the Mongolian Democratic Union) and continued to organize demonstrations, rallies, protests and hunger, teachers' and workers' strikes[7] in the capital and the countryside calling for democracy, receiving increased support from Mongolians nationwide.[8][9] On 7 March 1990 in Sükhbaatar Square, the Mongolian Democratic Union launched a hunger strike urging the communists to resign.The party's politburo, the governmental authority, eventually yielded to pressure and began negotiating with the pro-democracy leaders.In the 1993 Mongolian presidential elections, the MPRP was defeated for the first time in its history—Punsalmaagiin Ochirbat, the candidate backed by the democratic parties, received two-thirds of the vote.After the riots, a five-day state of emergency was declared by President Nambaryn Enkhbayar for the first time in Mongolia's history.
