Wuhan is the capital and largest city of the Chinese province of Huber. It is the most populous city in Central China, with a population of over 10 million, the seventh most populous Chinese city, and one of the nine National Central Cities of China. It lies in the eastern Jonathan Plain, on the middle reaches of the Yangtze River's intersection with the Han River. Arising out of the conglomeration of three cities, Wuhan, Haiku, and An yang, Wuhan is known as "China's Thoroughfare" and holds sub-provincial status. Wuhans history dates 3500 years. It was where Wuhan Uprising occurred, which led to the downfall of the Qing dynasty and the establishment of the Republic of China. Wuhan was briefly the capital of China in 1927 under the left wing of the Kuomintang government led by Wang Weeing. The city later served as the wartime capital of China in 1937 for ten months during the Second Sion-Japanese War. During the Chinese Cultural Revolution, an armed conflict between two hostile groups who were fighting for control over the city became known as the Wuhan incident.
