Mongolia (formerly Outer Mongolia) declares independence from China

Outer Mongolia was the name of a territory in the Manchu-led Qing dynasty of China from 1691 to 1911.

Outer Mongolia was the name of a territory in the Manchu-led Qing dynasty of China from 1691 to 1911. It corresponds to the modern-day independent state of Mongolia and the Russian republic of Tuva.

The historical region gained de facto independence from Qing China during the Xinhai Revolution and the Republic of China formally recognized the independence of Mongolia on January 5, 1946. This was revoked in 1953 after the Soviet Union violated the Sino-Soviet Treaty of Friendship and Alliance and the ROC reasserted claims to Outer Mongolia, a claim that would continue to appear in ROC maps until 2002 when the Democratic Progressive Party-led government re-recognized Mongolia.
