Sudan, 1985 — military coup attempt

Sudan (SDN)North Africa, AfricaSeptember 25, 1985

Event Summary

The dataset records an event coded as an attempted military coup in Sudan on 25 September 1985 during the rule of the Transitional Military Council, the body led by Field Marshal Abdel Rahman Swar al-Dahab that had taken power in the April 1985 coup which overthrew the longtime dictator Gaafar Nimeiry. That transitional council governed Sudan for a single year, having pledged to restore democracy, and it presided over a fragile and contested period marked by the ongoing civil war in the south, economic crisis, and jockeying among political forces and within the military itself over the shape of the promised civilian government. A coup attempt or plot in September 1985 came within that unstable interregnum and did not derail the transition.

Swar al-Dahab kept his promise, and after elections in April 1986 the council handed power to a civilian government led by Prime Minister Sadiq al-Mahdi, a rare voluntary return of power by a military regime, before Sudan's democratic experiment was again cut short by Omar al-Bashir's Islamist coup in 1989.

Editorial Note

No discrete documentation of a coup attempt precisely on 25 September 1985 in Sudan was found in accessible English sources this session; the dataset date does NOT match the successful 6 April 1985 Swar al-Dahab coup that ousted Nimeiry (a separate successful event), so this September record is framed within the verified context of the Transitional Military Council interregnum, with the specific event and plotters unconfirmed, flagged as context only. Continues the long Sudan run.

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: The Transitional Military Council under Swar al-Dahab weathered the September 1985 plotting and handed power to civilians in 1986.

Baseline coding: Coup attempt failed to remove the incumbent. 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.
