The Fengtian Army was a military force in China during the early 20th century, primarily associated with the warlord era. It was established by Zhang Zuolin, a prominent warlord in the Fengtian Province (now part of Liaoning). The army played a significant role in regional conflicts and the struggle for power during the chaotic period following the fall of the Qing Dynasty. The Fengtian Army was known for its strong organization and effective military strategies. It often clashed with other warlord factions, such as the Zhili Army, leading to various battles and shifting alliances. The army's influence waned after Zhang Zuolin's assassination in 1928, marking a decline in its power and significance in Chinese history.
