Nigeria, 2025 — military coup conspiracy

Nigeria (NGA)West Africa, AfricaOctober 23, 2025

Event Summary

This entry is coded 23 October 2025, within the window of an alleged October 2025 coup plot against President Bola Tinubu of Nigeria. The Defence Headquarters announced on 4 October 2025 the arrest of 16 senior officers, ranging from captain to brigadier-general, officially attributing it to indiscipline and breach of service regulations linked to frustration over failed promotions. Through October, however, security sources and Nigerian media reported that the officers had in fact been detained over a plot to overthrow, and possibly assassinate, Tinubu, and that the arrests were tied to the abrupt cancellation of the 1 October Independence Day parade.

On 18 October the military issued a fresh statement insisting the case was purely disciplinary. Reporting linked the alleged plot to a joint DSS and army intelligence operation around 30 September, named a brigadier-general and a returning officer among the suspects, and pointed to a former southern governor investigated over alleged financing. The government initially denied any coup, but in January 2026 acknowledged that several officers would be tried for plotting to overthrow the government.

The 23 October 2025 coding falls within this October 2025 window as the affair unfolded.

Editorial Note

Coded 23 Oct 2025 falls within the October 2025 window as the affair developed (16 officers' arrest announced 4 Oct; parade cancelled 1 Oct; further disclosures and a fresh military statement 18 Oct). Government initially denied a coup, then acknowledged in Jan 2026 the officers would be tried for plotting to overthrow the government. First Nigeria record in the run.
