Wuhan is the capital of Hubei province, China, and is the most populous city in Central China. It lies in the eastern Jianghan Plain at the intersection of the middle reaches of the Yangtze and Han rivers. Arising out of the conglomeration of three cities, Wuchang, Hankou, and Hanyang, Wuhan is known as "Jiusheng Tongqu (the nine provinces' leading thoroughfare)"; it is a major transportation hub, with dozens of railways, roads and expressways passing through the city and connecting to other major cities. Because of its key role in domestic transportation, Wuhan was sometimes referred to as "the Chicago of China" by foreign sources.
Holding sub-provincial status, Wuhan is recognized as the political, economic, financial, cultural, educational and transportation center of central China. The city of Wuhan, first termed as such in 1927, has a population of 10,607,700 people as of 2015. In the 1920s, Wuhan was the national capital of a leftist Kuomintang (KMT) government led by Wang Jingwei in opposition to Chiang Kai-shek, as well as wartime capital in 1937. At the 2010 census, its built-up (or metro) area made of 8 out of 10 urban districts (all but Xinzhou and Hannan not yet conurbated) was home to 8,821,658 inhabitants.
