The Fengtian clique's Zhili Army was a Chinese Warlord Era fighting force that controlled the Republic of China's Zhili province from 1924 until 1928, with the exception of a few months in 1925/26. Not related to the Zhili clique, it instead originated as Fengtian Second Army and operated as part of the Fengtian clique's armed forces. It was led by two successive Fengtian warlords, Li Jinglin and Chu Yupu, who always followed the orders of Zhang Zuolin, the Fengtian clique's overall leader. Although the Zhili Army's quality declined after 1925, it distinguished itself in numerous battles until it was disbanded in 1928 after being defeated by the National Revolutionary Army in the Northern Expedition.

Zhang Zongchang, courtesy name Xiaokun, was a Chinese warlord who ruled Shandong from 1925 to 1928. A member of the Fengtian clique, Zhang was notorious for his brutal and ruthless behavior, eccentric personality, and extravagant lifestyle, which earned him nicknames such as the "Dogmeat General"; Time dubbed him China's "basest warlord". Zhang's troops were defeated by the National Revolutionary Army during the Northern Expedition in 1928, and he fled to Japan before returning to Shandong in 1932, where he was assassinated by a young officer.
