In the 19th century, the Eight Banners and Green Standard troops proved unable to put down the Taiping Rebellion and Nian Rebellion on their own. Regional officials like Zeng Guofan were instructed to raise their own forces from the civilian population, leading to the creation of the Xiang Army and the Huai Army, among others. Along with the Ever Victorious Army of Frederick Townsend Ward, it was these warlord armies (known as "yongying") who finally succeeded in restoring Qing control in this turbulent period.
