El Salvador, 1960 — military coup conspiracy

El Salvador (SLV)Central America, AmericasNovember 17, 1960

Event Summary

This entry is coded 17 November 1960, three weeks after the actual overthrow of President Jose Maria Lemus. On 26 October 1960 a bloodless coup deposed Lemus and installed a six person Junta of Government of three officers and three civilians, led by Colonel Cesar Yanes Urias, which drifted leftward and promised free elections. The 17 November coding sits inside the wider Central American wave of plotting that followed.

A U.S. State Department intelligence note dated 14 November 1960 recorded that the leftward turning junta in El Salvador had been followed by attempts against the Ydigoras government in Guatemala and the Somoza government in Nicaragua, with Guatemala and Nicaragua both blaming Castro.

The Salvadoran junta itself was overthrown on 25 January 1961 by a conservative countercoup that formed the Civic Military Directory under Colonel Julio Adalberto Rivera, so the November window belongs to the brief and unstable junta interregnum rather than to a discrete named plot.

Editorial Note

Date discrepancy noted. CSP codes this as a 17 Nov 1960 conspiracy, but the actual Lemus overthrow was 26 Oct 1960 (a separate Successful event). The November window is best read as the unstable junta interregnum and the regional plotting wave documented by contemporary FRUS reporting. No single discrete plot is dated 17 Nov 1960 in the sources located this session; treated as context.

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: President Lemus was already deposed on 26 October 1960; the leftward junta then ruled until the January 1961 countercoup.

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.
