Liberia, 1963 — military coup attempt

Liberia (LBR)West Africa, AfricaFebruary 5, 1963

Event Summary

The dataset records an attempted military coup in Liberia on 5 February 1963, during the long dominant rule of President William V. S. Tubman and the True Whig Party, the Americo Liberian oligarchy that had governed the country continuously since the nineteenth century.

Tubman, in power since 1944, maintained a tight one-party system through patronage, his Unification Policy toward the indigenous majority, and a pervasive security apparatus, while opening the economy to foreign investment under his Open Door Policy. His long tenure saw periodic conspiracies and alleged plots, which the regime used to justify crackdowns on opponents. No widely documented military coup attempt in Liberia on this date appears in accessible English sources, and Tubman's rule was not overturned; he continued as president until his death in office in 1971, when his vice president William Tolbert succeeded him, the True Whig monopoly enduring until the 1980 coup.

Editorial Note

No discrete documentation of a 5 February 1963 military coup attempt in Liberia was found in accessible English sources this session; the entry records the dataset's coding and the verified context of the entrenched Tubman True Whig regime, with the specific event unconfirmed and openly flagged as context only. Liberia had no successful coup until 1980.

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.
