Keypoints:
- Alliances across the Horn of Africa are shifting again
- Ethiopia’s maritime ambitions heighten regional tension
- External powers deepen geopolitical competition
MORE than three years after Ethiopia’s devastating civil war formally ended, the fragile political order that followed is beginning to fracture. What once appeared to signal stability increasingly reflects deeper structural pressures shaping Horn of Africa security dynamics across one of Africa’s most strategically sensitive regions.
The 2022 peace agreement between Ethiopia’s federal government and leaders in the Tigray region halted Ethiopia’s civil war, a conflict that killed hundreds of thousands and displaced millions. Yet the settlement addressed immediate battlefield realities while leaving unresolved regional grievances and security rivalries beneath the surface.
Crucially, Eritrea — a decisive military participant during the war — was not fully integrated into the political framework that ended hostilities. That omission now appears increasingly consequential as tensions resurface.
Historical rivalries and shifting alliances
Relations among Ethiopia, Eritrea and Tigray have rarely followed predictable lines. Eritrea fought a prolonged independence struggle against Ethiopia before achieving sovereignty in the early 1990s. Decades later, Eritrean forces aligned with Prime Minister Abiy Ahmed during the Tigray war, transforming former adversaries into tactical partners.
Today, diplomatic signals suggest another reversal. Reports of troop deployments along the border indicate rising Ethiopia–Eritrea tensions, reflecting growing mistrust between Addis Ababa and Asmara.
These shifts underscore a defining feature of regional politics: alliances are often transactional, shaped by immediate security concerns rather than lasting ideological alignment.
Geography and Ethiopia’s maritime dilemma
Beyond historical grievances, geography has emerged as a central driver of Ethiopia’s current posture. Since Eritrea’s independence, Africa’s second-most populous country has remained landlocked, relying heavily on neighbouring ports for trade access.
Prime Minister Abiy Ahmed has increasingly framed the issue as an economic constraint, arguing that logistics limitations hinder national growth. Debate surrounding Ethiopia’s search for sea access has therefore moved from economic discussion into strategic policy thinking.
For neighbouring states, such rhetoric raises concerns about whether economic necessity could eventually translate into geopolitical assertiveness. Maritime access is no longer viewed solely as a commercial issue but as a question tied to sovereignty, influence and long-term regional power balance.
A fragile regional environment
Renewed tensions are unfolding within an already volatile regional landscape. Tigray continues to recover slowly from wartime devastation, facing reconstruction challenges and humanitarian pressures that remain unresolved.
At the same time, instability linked to Sudan’s ongoing conflict has intensified regional strain, limiting diplomatic capacity for crisis prevention. Further south, Somalia’s prolonged insurgency continues to complicate efforts at coordinated security cooperation.
These overlapping crises increase the risk that even limited confrontations could trigger wider instability across East Africa.
External powers and competing interests
Regional rivalries are also shaped by growing involvement from external actors seeking influence along critical trade and energy corridors. The United Arab Emirates has strengthened financial and political ties with Ethiopia in recent years, while Egypt and Saudi Arabia maintain closer relationships with Eritrea and other regional stakeholders.
Much of this competition intersects with the Grand Ethiopian Renaissance Dam dispute, which remains central to tensions between Ethiopia and downstream Nile states concerned about water security and long-term resource control.
As global and regional interests converge, local disputes increasingly carry international consequences, transforming bilateral disagreements into broader geopolitical contests.
Why this moment matters
Current developments do not represent a sudden crisis but the re-emergence of unresolved structural tensions left behind by earlier conflicts. The peace agreement ended active fighting without settling deeper questions surrounding borders, economic access and regional security arrangements.
As military activity increases and political rhetoric sharpens, the Horn of Africa once again faces the possibility that competing national ambitions could converge into a wider confrontation.
The region’s history suggests lasting stability will depend less on temporary alliances than on addressing foundational drivers of rivalry — geography, resources and strategic access. Until those issues are resolved, the Horn of Africa remains poised between fragile recovery and renewed conflict.
