The Beiyang Army (Chinese: 北洋軍; pinyin: Běi Yáng Jūn; lit. 'Northern Ocean Army'), named after the Beiyang region, was an army established by Yuan Shikai in 1895. It was the centerpiece of a general overhaul of the Qing military system in the wake of the Boxer Rebellion and the First Sino-Japanese War, becoming the dynasty's first regular army in terms of its training, equipment, and structure. The Beiyang Army played a major role in Chinese politics for at least three decades and arguably right up to 1949. It played an instrumental role in the 1911 Revolution against the Qing dynasty, and, by dividing into warlord factions known as the Beiyang clique (Chinese: 北洋軍閥; pinyin: Běiyáng Jūnfá), ushered in a period of regional division.
The Beiyang Army had its origins in the Newly Created Army established in late 1895 under Yuan Shikai's command, after China was defeated in the First Sino-Japanese War. Unlike its predecessors, it had a formal structure with infantry, cavalry, artillery, and logistical branches, and maintained strict training and discipline. The brigade-sized force was expanded over the years with new recruits and by incorporating other units, before serving as the core of a larger army after Yuan was appointed the Viceroy of Zhili and Minister of Beiyang in 1901. The tensions in Manchuria leading up to the Russo-Japanese War caused Empress Dowager Cixi to accept Yuan's request to raise more divisions, and he also used his influential position in the Army Reorganization Bureau to prioritize its funding. By 1907 the Beiyang Army had 60,000 men organized in six divisions, some of whom served in the Inner City of Beijing as the emperor's palace guard, and on the eve of the 1911 Revolution it was the strongest military force of the Qing dynasty.
