Nigeria, 1997 — military coup conspiracy
Event Summary
This entry is coded 22 December 1997, corresponding to the December 1997 alleged coup plot against Nigerian military ruler General Sani Abacha, centered on his deputy, Chief of General Staff Lieutenant General Oladipo Diya. On the night of 21 December 1997, Abacha's government arrested Diya, the de facto vice president, along with Major Generals Tajudeen Olanrewaju and Abdulkarim Adisa, several colonels, and civilians, accusing them of plotting to overthrow the regime. By one plotter's later account, the plan was to capture Abacha at a military conference in Enugu on 9 December, force him to resign, and change the government, but Abacha's unexpected return to the presidential villa foiled it; Diya had also narrowly survived a bomb blast at Abuja airport days earlier.
A special military tribunal under General Victor Malu sentenced Diya and five others to death in April 1998. Diya maintained he had been entrapped by Chief of Army Staff Ishaya Bamaiyi and called it a phantom coup, and critics saw a purge of Yoruba officers. After Abacha's death in June 1998, the successor government pardoned and released the accused.
The 22 December 1997 coding matches the announcement of the arrests.

Editorial Note
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: Abacha jailed his deputy and the alleged plotters; they were freed after his 1998 death.
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.
