The Wuwei Corps (simplified Chinese: ; traditional Chinese: ; pinyin: Wǔwèijūn; Wade–Giles: Wu-wei chün) or Guards Army was a modernised army unit of the Qing dynasty. Made up of infantry, cavalry and artillery, it was formed in May or June 1899 and trained by western military advisers. The guard took responsibility for the security of Peking (Beijing) and the Forbidden City, with Ronglu as its supreme commander. This move was an attempt by the Qing imperial court to create a western-style army equipped with modern weaponry following the Qing Empire's defeat in the First Sino-Japanese War. Four out of the five divisions of the Wuwei Corps were disbanded after two years due to attrition caused by the Boxer Rebellion.
Empress Dowager Cixi held supreme power at the Qing imperial court after she placed the Guangxu Emperor under house arrest. Ronglu, who controlled the Grand Council and the Ministry of Defence, subsequently received orders to recruit a 90,000-men army drawn from various units under the control of Nie Shicheng, Song Qing, Dong Fuxiang and Yuan Shikai.
The corps consisted of five "divisions" described as "regiments" by some sources:, Left, Right, Front, Rear, and Center
