At the beginning of the Han dynasty, Handan was Liu Bang's base for suppressing Chen Xi's rebellion in 197 and 196 BCE; it was still regarded as a regional center of culture and commerce at the end of the dynasty in the early 3rd century CE. It slowly declined, perhaps because of the numerous battles that ravaged northern China following the Han Dynasty, but maintained a reputation for its fine Cizhou ware well into the Qing dynasty (1644–1911). It was also the birthplace in the 19th century of Yang-style tai chi, one of Tai Chi's five major schools.
