Yemen Arab Republic, 1978 — military coup attempt

Yemen Arab Republic (YAR)Western Asia, AsiaOctober 15, 1978

Event Summary

The dataset records an attempted military coup in the Yemen Arab Republic, or North Yemen, on 15 October 1978, during the early and highly precarious rule of President Ali Abdullah Saleh, who had taken power only in July 1978 after the assassinations in quick succession of his two predecessors, Ibrahim al-Hamdi in 1977 and Ahmad al-Ghashmi in June 1978. Saleh inherited a fractured country wracked by tribal rivalries, tension with Marxist South Yemen, and plotting within the divided military, and few observers expected him to survive long. In October 1978 a coup attempt was mounted against the new president, one of several early challenges he faced, and it was suppressed, with the plotters arrested and a number executed.

Against all expectations Saleh consolidated his position through patronage, tribal balancing, and force, going on to rule North Yemen and then, after the 1990 unification, all of Yemen for more than three decades until he was forced from power in the Arab Spring uprising of 2011 to 2012.

Editorial Note

Dataset date 15 October 1978 corresponds to an early coup attempt against the newly installed Saleh; the day level detail and plotter identities are lightly documented in accessible English sources this session, so specifics are flagged, while Saleh's precarious accession, the pattern of early plots, and his survival are verified. First Yemen Arab Republic record in the dataset run to reach this era.
