The Húběi area first came to prominence during the Eastern Zhou (700–221 BC), when the powerful Chu kingdom, based in present-day Jīngzhōu, was at its height. Húběi again became pivotal during the Three Kingdoms (AD 220–280). The Chinese classic The Romance of the Three Kingdoms (Sān Guó Yǎnyì) makes much reference to Jīngzhōu. The mighty Yangzi River (Cháng Jiāng) ensured prosperous trade in the centuries that followed, especially for Wǔhàn, China’s largest inland port and stage of the 1911 uprising, which led to the fall of the Qing and the creation of the Republic of China.
