Politics of Mongolia takes place in a framework of a semi-presidential representative democratic republic, and of a multi-party system.Executive power is exercised by the President and the Government. Legislative power is vested in both the government and parliament. The Judiciary is independent of the executive and the legislature.
From shortly after the Mongolian Revolution of 1921 until 1990, the Mongolian Government was modeled on the Soviet system; only the communist party—the Mongolian People's Revolutionary Party (MPRP)—was officially permitted to function. After some instability during the first two decades of communist rule in Mongolia, there was no significant popular unrest until December 1989. Collectivization of livestock, introduction of agriculture, and the extension of fixed abodes were all carried out without perceptible popular opposition.
The birth of perestroika in the former Soviet Union and the democracy movement in Eastern Europe were seen in Mongolia. On the morning of 10 December 1989, the first open pro-democracy demonstration met in front of the Youth Cultural Center in Ulaanbaatar. There, Tsakhiagiin Elbegdorj announced the creation of the Mongolian Democratic Union. Over the next months activists 13 democratic leaders continued to organize demonstrations, rallies, protests and hunger strikes, as well as teachers' and workers' strikes. Activists had growing support from Mongolians, both in the capital and the countryside and the union's activities led to other calls for democracy all over the country. After extended demonstrations of many thousands of people in subzero weather in the capital city as well as provincial centers, Mongolian People's Revolutionary Party (MPRP) (present Mongolian People's Party)'s Politburo – the authority of the government eventually gave way to the pressure and entered negotiations with the leaders of the democratic movement.Jambyn Batmönkh, chairman of Politburo of MPRP's Central Committee decided to dissolve the Politburo and to resign on 9 March 1990. Thus paved the way for the first multi-party elections in Mongolia. Tsakhiagiin Elbegdorj announced this news to the hunger strikers and the people those gathered on Sükhbaatar Square at 10PM on that day after the negotiations between leaders of MPRP and Mongolian Democratic Union. As a result, Mongolia became the first successful country in Asia to transition into democracy from communist rule. Elbegdorj worked as the Leader of the Mongolian Democratic Union in 1989–1997.
