Northern ExpeditionThe Northern Expedition (北伐) was a military campaign lead by Chiang Kai-Shek in 1927 intended to unify China under the rule of the Kuomintang and ending the rule of local warlords. It was largely successful at these objectives. During the Northern Expedition, the Kuomintang and the Communist Party of China were cooperating with each other.
The Northern Expedition began from a base area in Guangdong province. Chiang was able to achieve victory over the warlords in large part because both the National Revolutionary Army and the Kuomintang were far better organized than the warlord armies which they faced. In addition, Chiang had the advantage of a chain reaction affect as victory over one warlord encouraged others to defect to Chiang which strengthened his position even more.
