Mongolian People's Republic since the
Mongolian Revolution of 1921. Following
mass pro-democracy demonstrations organized by the
Mongolian Democratic Union (MDU) in late 1989 and early 1990, the
General Secretary of the MPRP,
Jambyn Batmönkh, and other
politburo leaders announced their resignation in March 1990, paving the way for democratic change in Mongolia. Economist
Dashiin Byambasüren (MPRP) was appointed the next prime minister on 11 September, along with the
president and the
vice president. Despite the MPRP's majority, Byambasüren established a
grand coalition government with the opposition MDP and the MNPP in September 1990. The chairman of the MNPP,
Davaadorjiin Ganbold, became the
First Deputy Prime Minister, while deputy chairman of the MDP,
Dambiin Dorligjav, became
Deputy Prime Minister. In April 1991, political developments within the MDU, Mongolia's largest non-governmental pro-democracy organization, led
Sanjaasürengiin Zorig, a key leader of the 1990 revolution, to resign from his positions in the MDU. He also left the MDP to establish the Republican Party () in June 1991. Later in February 1992, his party merged with the Free Labour Party and factions of the MDU In January 1992, a
new constitution was ratified, which renamed the country
Mongolia and established a
