The National Day of the Republic of China, also referred to as Double Ten Day or Double Tenth Day, is a public holiday on 10 October, now held annually as national day in the Republic of China. It commemorates the start of the Wuchang Uprising on 10 October 1911 which ultimately led to the establishment of the Republic of China on 1 January 1912, and the collapse of the imperial Qing dynasty, ending 2,133 years of imperial rule of China since the Qin dynasty. The day was once held as a public holiday in mainland China during the Mainland Period of the ROC before 1949. The subsequent People's Republic of China continues to observe the Anniversary of the Xinhai Revolution on the same date but not as a public holiday and places more emphasis on its revolutionary characteristics as a commemoration of a historical event rather than celebrating it as the founding of the Republic of China.
