After numerous demonstrations of many thousands of people in the capital city as well as provincial centers, on 4 March 1990, the MDU and three other reform organizations held a joint outdoor mass meeting, inviting the government to attend. The government sent no representative to what became a demonstration of over 100,000 people demanding democratic change. Ten members of the organizations began a hunger strike on 7 March, the next day, 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 Mongolian Democratic Union. Jambyn Batmönkh, chairman of Politburo of MPRP's Central Committee decided to dissolve the Politburo and to resign on 9 March 1990. This paved the way for the first multi-party elections in Mongolia.
