The Beiyang Army was a powerful, Western-style Imperial Chinese Army established by the Qing Dynasty government in the late 19th century. It was the centerpiece of a general reconstruction of Qing China's military system. The Beiyang Army played a major role in Chinese politics for at least three decades and arguably right up to 1949. It made the Xinhai Revolution of 1911 possible, and, by dividing into warlord factions known as the Beiyang Clique, ushered in a period of regional division.
