On October 1, 1949, Mao Zedong proclaimed the founding of the People's Republic of China from the Tiananmen Gate in Beijing, marking the decisive Communist victory in the Chinese Civil War and the effective fall of the Nationalist government on the mainland. The proclamation followed the Communist crossing of the Yangtze in April, the capture of the Nationalist capital Nanjing, and the fall of Shanghai, Guangzhou, and other cities through 1949. The Soviet Union recognized the new state the next day.
Chiang Kai-shek and the remnants of the Republic of China government, together with some six hundred thousand troops and roughly two million refugees, retreated to Taiwan, completing the evacuation by December and declaring Taipei the temporary capital. The Republic of China continued to claim to be the legitimate government of all China from the island.

Editorial Note
The Cline dataset codes 1 October 1949 as a successful rebel coup with the leadership fleeing the country, which corresponds to the PRC proclamation and the Nationalist government's flight to Taiwan rather than a single-day palace action. Sources uniformly confirm the date, Mao's proclamation, and the Nationalist retreat. Three encyclopedic/primary sources plus the State Department milestone were read directly. This complements the separate 21 January 1949 record on Chiang's earlier step-down.
Cross-Reference
Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
Identifiers for finding this same event in the other datasets:
Coup Atlas research identifies the target as: Chiang Kai-shek and the Republic of China Nationalist government (defeated on the mainland; fled to Taiwan).
Baseline coding: Incumbent executive removed from power. Recorded leader fate: deposed; fled the country. The baseline file does not name individual targets; researched names are kept in a separate layer.
