Egypt, 1958 — dissident coup conspiracy

Egypt (EGY)North Africa, AfricaMarch 5, 1958

Event Summary

On 5 March 1958, Egyptian president Gamal Abdel Nasser announced in a Damascus speech that a plot had been uncovered against the newly formed United Arab Republic, the union of Egypt and Syria established on 1 February 1958. The plot was a Saudi-backed conspiracy, sponsored by King Saud, to assassinate Nasser and break up the UAR through a coup in Syria. On 6 March the UAR intelligence chief Colonel Abdel Hamid Sarraj revealed that Saud had paid him roughly 2 million pounds to place a bomb aboard Nasser's plane, and the government produced checks allegedly given to the plotters; the United States was also implicated and denied involvement.

The foiled plot backfired dramatically: on 24 March 1958 the Saudi royal family stripped King Saud of most of his powers in favor of Crown Prince Faisal. The affair strengthened Nasser's grip on Syria and removed his most powerful conservative Arab rival.

Editorial Note

Exact date match: the coded 5 March 1958 is precisely when Nasser announced the discovered plot against the UAR. Coded as Egypt/Dissident because Nasser, the Egyptian president of the UAR, announced it as a conspiracy against the union. Well documented as the King Saud plot. First Egypt record in this batch tied to a discrete dated conspiracy.

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.
