Xiao, empress of the Sui dynasty

Empress Xiao, formally Empress Min, was an empress of the Chinese Sui dynasty. Her husband was Emperor Yang of Sui.

The Sui dynasty was a short-lived Chinese imperial dynasty that ruled from 581 to 618. The re-unification of China proper under the Sui brought the Northern and Southern dynasties era to a close, ending a prolonged period of political division since the War of the Eight Princes. The Sui endeavoured to rebuild the country, re-establishing and reforming many imperial institutions; in so doing, the Sui laid much of the foundation for the subsequent Tang dynasty, who after toppling the Sui would ultimately preside over a new golden age in Chinese history. Often compared to the Qin dynasty (221–206 BC), the Sui likewise unified China after a prolonged period of division, undertook wide-ranging reforms and construction projects to consolidate state power, and collapsed after a brief period.
