A report on Shanghai massacre

Midway through the Northern Expedition, the KMT–CCP alliance broke down and Chiang massacred communists inside the party, triggering a civil war with the CCP (Chinese Communist Party), which he eventually lost in 1949.

Chiang's expulsion of the CCP and their Soviet advisers, marked by the Shanghai massacre on 12 April, led to the beginning of the Chinese Civil War.

The split was partially motivated by Chiang's purging of communists within the KMT, which marked the end of the First United Front.

Although the communists welcomed Chiang's arrival, he turned on them, massacring 5,000 with the aid of the Green Gang.

The CCP referred to this as the 12 April Incident, the White Terror or Shanghai Massacre.

Chiang Kai-shek occupied Shanghai in April 1927, and began a bloody suppression of suspected communists known as the "White Terror".

The split was partially motivated by the purge of the Communists within the party, which marked the end of the First United Front, and Chiang Kai-shek briefly stepped down as the commander of the National Revolutionary Army.

Its success led to the split of the KMT between Wuhan and Nanking and the purge of the communists in the April 12 Incident.

In 1927, KMT leader Chiang Kai-shek purged the Communists from the Front while the Northern Expedition was still half-complete.

When the Communists and the Kuomintang split in 1927, marking the start of the Chinese Civil War, each group claimed to be his true heirs, a conflict that continued through World War II.
