Laos, 1971 — military coup conspiracy
Event Summary
This entry is coded 6 April 1971, during the strained neutralist coalition government of Prince Souvanna Phouma in the Kingdom of Laos, at the height of the Second Indochina War. Souvanna had led the fragile tripartite coalition since 1962, trying to keep Laos neutral even as North Vietnamese forces used eastern Laos for the Ho Chi Minh Trail and the United States waged a massive covert bombing campaign, the Secret War. Rightist elements of the Royal Lao Army, with power bases in the Vientiane region, had a long record of coup plotting against Souvanna's coalition, viewing it as opening the way to Communist encroachment.
In February and March 1971 the South Vietnamese, backed by U.S. air power, launched Operation Lam Son 719 into southern Laos to cut the trail, but after heavy fighting the offensive collapsed into a ragged retreat by late March.
The April 1971 coding sits in this period of military setback and heightened rightist frustration with the neutralist order.

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.

Outcome and Target
Coup Atlas research identifies the target as: Souvanna Phouma remained prime minister; his coalition survived until the Pathet Lao takeover of 1975.
Baseline coding: Plot discovered and disrupted before execution. Recorded leader fate: remained in office; not physically harmed. The baseline file does not name individual targets; researched names are kept in a separate layer.
