Double Ten Day is the national day of the Republic of China and celebrates the start of the Wuchang Uprising of October 10, 1911, which led to the collapse of the Qing Dynasty in China and establishment of the Republic of China on January 1, 1912. It is therefore designated by the government as National Celebration Day.
As a result of the Chinese Civil War, the Government of the Republic of China lost control of mainland China and relocated to Taiwan in 1949. The National Celebration Day is now mainly celebrated in the Free Area which remains under control of the Republic, but is also celebrated by some Overseas Chinese.
