Yemen Arab Republic, 1948 — rebel coup attempt

Yemen Arab Republic (YAR)Western Asia, AsiaFebruary 17, 1948

Event Summary

On 17 February 1948 the Alwaziri coup struck the Mutawakkilite Kingdom of Yemen: an assassin from the Bani Murad tribe shot and killed Imam Yahya Muhammad Hamid ed Din, ruler since 1918, near Sanaa, and the rival sayyid family of the al-Wazirs seized the capital, proclaiming Abdullah bin Ahmed al-Wazir as imam at the head of a self-styled constitutional government backed by Free Yemeni reformists. The dynastic overthrow failed. Crown Prince Ahmad bin Yahya escaped, rallied the northern tribes behind his claim to the imamate, and encircled Sanaa; in mid-March 1948 his forces retook the city, at the price of allowing a seven day tribal sack of the capital in which as many as a quarter million tribesmen took part.

Abdullah al-Wazir was deposed and beheaded on 8 April 1948. The episode, which cost around 5,000 lives, restored Hamidaddin rule under Imam Ahmad and foreshadowed the revolutions that ended the imamate in 1962.

Editorial Note

The dataset's leader fate of remained in office and killed reflects the unusual outcome: the ruler was assassinated yet the incumbent dynasty defeated the coup, so it is coded attempted. Dataset country label Yemen Arab Republic is anachronistic for 1948, when the state was the Mutawakkilite Kingdom of Yemen; noted, base record left untouched. Links forward to the 1955 attempt against Ahmad and the 1962 revolution.

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.
