It marks Mongolia's independence from Manchu’s Qing Dynasty - not current China in 1911.

The 1911 National Revolution of Independence, which marked the beginning of the Mongolian people's independence from Manchu’s Qing Dynasty, is a special page in the history of the Mongolian people with an ancient tradition of statehood, and a historical event that future generations should remember with pride.

This National Independence Revolution was the embodiment of the Mongolian people's decades-long unyielding desire and persistent struggle to restore their independent state, the beginning of the great revival of national consciousness, and the actual grounds and basis for the Mongolian Revolution of 1921.

Although the value of this historically important day was ignored during the socialist years, the Parliament's law on August 16, 2007, established December 29 as a public holiday, and then the law on December 23, 2011 established it as a public holiday, the Day of Restoration of National Freedom and Independence.

In 1911, the Xinhai Revolution broke out and including both Outter and Inner Mongolia declared its independence on December 29, 1911.
