National Independence Day is observed in Mongolia every December 29, commemorating the declaration of independence from the Manchu Qing Empire and the establishment of the Republic of Mongolia in 1911. The day marks a significant historical moment when Mongolia, under the leadership of Bogd Khaan, declared its autonomy following the overthrow of the Qing dynasty during the Xinhai Revolution. Although the newly formed republic faced challenges, including occupations by the Republic of China in 1919 and Russia in 1921, the day is celebrated with a variety of festive events across the country. Mongolians engage in various activities to honor their national identity and history, making this public holiday an important occasion in the nation’s calendar.
