Ulaanbaatar was the site of demonstrations that led to Mongolia's transition to democracy and market economy in 1990. On 10 December 1989, protesters outside the Youth Culture Centre called for Mongolia to implement perestroika and glasnost in their full sense. Dissident leaders demanded free elections and economic reform. On 14 January 1990, the protesters, having grown from two hundred to over a thousand, met at the Lenin Museum in Ulaanbaatar. A demonstration in Sükhbaatar Square on 21 January followed. Afterwards, weekend demonstrations in January and February were held accompanied by the forming of Mongolia's first opposition parties.
