The Northern Expedition (1926-1928) was the offensive undertaken
by the armies of the Guangzhou-based Kuomintang Party to unite
China under their rule, ending more than a decade of fragmented
rule by shifting alliances of provincial warlords. In 1924,
Whampoa Military Academy had been founded in Canton. General
Chiang Kai-shek was the commander of it. The troops were trained
by the Red Army and equipped with Soviet arms. Unfortuantely,
many turned into communists. Chiang commanded the Northern
Expedition which took over China. He then suppressed the reds to
keep order and prevent a Leninist tyranny.
