The National Day of the Republic of China, also referred to as Double Ten Day or Double Tenth Day, is the national day of the Republic of China. It commemorates 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. 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 Day is now mainly celebrated in Taiwan, but is also celebrated by some Overseas Chinese. (With material from: Wikipedia)
