孫伝芳
In 1926, there were three major coalition of warlords across China that were hostile to the KMT government in Guangzhou. The forces of Wu Peifu occupied northern Hunan, Hubei, and Henan provinces. The coalition of Sun Chuanfang was in control of Fujian, Zhejiang, Jiangsu, Anhui and Jiangxi provinces. The most powerful coalition, led by Zhang Zuolin, head of the Beiyang government and the Fengtian clique, was in control of Manchuria, Shandong and Zhili. To face the Northern Expedition, Zhang Zuolin eventually assembled the "National Pacification Army" (; NPA), an alliance of the warlords of northern China.
