Chinese emperors family tree (middle)
The following is a simplified family tree for the Tang dynasty (唐朝), which ruled China between AD 618 and 907. The Tang dynasty was interrupted by the reign of Empress Wu Zetian (AD 690–705), who after deposing her sons, declared herself the founder of a second Zhou (周) dynasty; the Tang dynasty was resumed by her sons following her abdication. The dynasty was named for the family title: the Li (李) family were the Dukes of Tang.
