Second United Front

The Second United Front (traditional Chinese: 第二次國共合作; simplified Chinese: 第二次国共合作; pinyin: dì èr cì guógòng hézuò; lit. 'Second Nationalist-Communist Cooperation') was the alliance between the ruling Kuomintang (KMT) and the Chinese Communist Party (CCP) to resist the Japanese invasion of China during the Second Sino-Japanese War, which suspended the Chinese Civil War from 1937 to 1945.

Background[edit]

In 1927 the Chinese Communists retaliated against Kuomintang following a betrayal of its members in Shanghai by National Revolutionary Army commander Chiang Kai-shek, which marked the end of the KMT's four-year alliance with the Soviet Union and its cooperation with the CCP during the Northern Expedition (aka First United Front) to defeat warlords and unify China.[2]


In 1931 the Japanese launched its invasion and subsequent occupation of Manchuria. Chiang Kai-shek, who de facto led the central government of China, decided that China must avoid all-out war with Japan due to domestic turmoil and inadequate preparation. Therefore, he "pursued a strategy of appeasing Japan while struggling for real national unity and over time sufficient strength to confront the Imperial army. This appeasement policy lasted for another six years".[3] Even though his campaigns against the Communists resulted in their retreat and a 90% reduction in their fighting strength, he was unable to eliminate their forces entirely, and his policy of "internal pacification before external resistance" ((in Chinese):攘外必先安内) was very unpopular with the Chinese populace, which caused widespread resentment and demonstration against the ruling KMT leadership and its regional warlord allies.[4]
