Wuhan is set at the confluence of the Yangtze River and Han River (the longest tributary of the Yangtze), on the west Jianghan Plain, a region that has more water area than land. It is the largest city in central China and the capital of Hubei Province . Wuhan is composed of three separate cities: Wuchang, Hankou, an Hanyang. Wuhan was first settled in the first century during the Three Kingdom era as a part of the Wu Kingdom. By the Yuan Dynasty(1279-1368), Wuhan was the capital of the region and was enclosed by a city wall until the end of the 19th century. Wuhan has played an important role in modern Chinese history. In the late 19th century, a farsighted official of the Qing Dynasty(1644-1911), Zhang Zhi Dong, established factories and an arsenal in Hanyang to begin the industrializing Movement of China. The 1911 revolution was first started here and caused the downfall of the last inperial dynasty in China . The first major in dustrial strike in Chinese history, the “February 7” railroad stike took place here in 1923. After the fall of Nanjing in 1937 during the Anti-Japanese War, the Nationalist government made Wuhan its capital for a year before moving to Chongqing . Tourist attractions include the Yellow Crane Tower , Yangtze River Bridge , East Lake, and the Hubei Provicial Museum , which houses artifacts from the first century BC, as well as mementos of the province's revolutionary history.
