Addis Ababa Agreement on the Problem of South Sudan
Also known as: Addis Ababa Agreement (1972)
Ended the first Sudanese civil war by granting the South regional autonomy within a united Sudan; its unilateral abrogation in 1983 reignited war and stands as the classic African case of implementation reversal.
Conflict Background
Seventeen years of southern insurgency ended through quiet mediation led by church bodies and Emperor Haile Selassie, producing a Southern Regional Government with legislative and executive organs in Juba.
Negotiation Context
The settlement rested almost entirely on President Nimeiry's personal commitment rather than entrenched constitutional guarantees — a structural weakness exposed as his coalition shifted toward Islamist constituencies.
Parties
- Government of Sudan (Nimeiry)
- Southern Sudan Liberation Movement (SSLM/Anyanya)
Mediators & Guarantors
- · Emperor Haile Selassie (Ethiopia)
- · World Council of Churches
- · All Africa Conference of Churches
- · Ethiopia
Key Provisions
Implementation
Abrogated in 1983. Its collapse directly shaped SPLM/A insistence on international guarantees and a self-determination exit in the 2005 CPA.
Timeline
- 1972-02-27Signed in Addis Ababa
- 1972-03Ratified as the Southern Provinces Regional Self-Government Act
- 1980Redivision debates and oil-boundary manoeuvres begin eroding southern autonomy
- 1983-06Nimeiry redivides the South and imposes September Laws; agreement effectively abrogated
- 1983SPLM/A launches the second civil war
Challenges
- No external guarantor with enforcement capacity once Ethiopian patronage shifted
- Autonomy protected by ordinary statute, not entrenched constitutional provision
- Oil discoveries near the north–south boundary created incentives to redraw it
Outcomes
- Delivered eleven years of peace — the longest quiet period in Sudan's post-independence history
- Demonstrated the effectiveness of faith-based and regional-monarch mediation
Lessons
- Autonomy arrangements require constitutional entrenchment and external guarantee
- Durable peace must survive the departure of the leader who signed it
- Resource discoveries near internal boundaries are a predictable stress test
