Republic of Vietnam, 1975 — military coup conspiracy
Event Summary
This entry is coded 26 March 1975, at the height of the collapse of South Vietnam during the North Vietnamese 1975 Spring Offensive, in a period of intensifying pressure and plotting against President Nguyen Van Thieu. After the fall of Ban Me Thuot in mid-March, Thieu ordered a disastrous abandonment of the Central Highlands that turned into a rout along Route 7B, and by late March the northern provinces were disintegrating, with Hue and Da Nang falling in the last days of the month. As the military situation cratered, Thieu came under mounting political attack over corruption and his handling of the war, with the National Assembly, Catholic and Buddhist figures, and the U.
S. station chief all pressing for his removal, and former premier Nguyen Cao Ky secretly organizing a coup. This wave of resignation and coup pressure culminated in Thieu's resignation on 21 April 1975, days before the fall of Saigon on 30 April.
The March coding sits in this collapse-era plotting against Thieu.

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.
