Though the dust from the devastating Tigray War of 2020–2022 has barely settled, the Horn of Africa once again appears to be drifting toward catastrophe. Recent developments suggest a growing risk of renewed conflict involving Ethiopia’s federal government, the Tigray People’s Liberation Front (TPLF), and neighboring Eritrea. Military buildups, drone strikes, and a rising chorus of diplomatic accusations all point to a region edging back toward war. Should fighting resume, the consequences would be severe: hundreds of thousands more lives potentially lost, humanitarian crises deepening, and the possibility of outside powers becoming entangled in yet another regional conflict.
To understand the present tensions, one must revisit the recent history that forged this volatile triangle. The Tigray War erupted in November 2020 when Ethiopian Prime Minister Abiy Ahmed launched a military offensive against the Tigray People’s Liberation Front, the dominant political force in the northern region of Tigray. The confrontation followed months of escalating disputes over regional elections and the authority of the federal government.
The roots of the crisis, however, run deeper still. Modern Eritrea itself emerged from the legacy of European imperialism. Italy established Eritrea as a colony in the late nineteenth century, administratively separating it from the Ethiopian highlands. Following the defeat of Benito Mussolini’s empire in World War II, Eritrea passed under British administration before being federated with Ethiopia in 1952. The federation proved short-lived. In 1962, Emperor Haile Selassie formally annexed the territory, sparking a thirty-year war of independence that ultimately ended with Eritrea’s internationally recognized statehood in 1993. That victory coincided with the rise of the TPLF, whose fighters played a central role in overthrowing the Marxist Derg regime in Addis Ababa in 1991. For nearly three decades thereafter, Tigrayan elites dominated Ethiopia’s ruling coalition, shaping the country’s system of ethnic federalism and wielding influence far out of proportion to Tigray’s small share of the population. The erosion of that dominance after 2018, when Abiy Ahmed rose to power amid growing Oromo and Amhara political mobilization, set the stage for the confrontation that erupted into war two years later.
What was initially described by Addis Ababa as a limited “law enforcement operation” quickly spiraled into one of the most destructive conflicts of the twenty-first century. Ethiopian federal forces fought alongside regional militias and troops from Eritrea, whose president, Isaias Afwerki, viewed the TPLF as a longstanding enemy. The war resulted in an estimated 600,000 deaths, most of them civilians, while millions were displaced and large portions of Tigray were pushed to the brink of famine.
The conflict formally ended with the Pretoria Agreement of November 2022, brokered under the auspices of the African Union. The agreement called for a cessation of hostilities, the disarmament of Tigrayan forces, and the restoration of humanitarian access. Yet implementation has been uneven, and the underlying political tensions remain unresolved.
Now, early in 2026, the fragile peace appears increasingly precarious. Reports from international media and regional observers describe a significant Ethiopian military buildup along Tigray’s borders. Convoys of troops, tanks, and artillery have reportedly been redeployed from other conflict zones, including the troubled regions of Amhara and Oromia. Ethiopia’s military has also employed drone strikes against suspected Tigrayan logistical sites in towns such as Enticho and Raya Azebo, actions that Tigrayan leaders say violate the spirit, if not the letter, of the Pretoria agreement.
The leadership of the TPLF, including longtime chairman Debretsion Gebremichael, has accused the federal government of preparing for a renewed offensive. Addis Ababa, for its part, claims that Tigrayan forces are rearming and violating the ceasefire. Meanwhile, Ethiopian officials have demanded that Eritrea withdraw troops from Ethiopian territory, describing their continued presence as a form of “military aggression.”
Perhaps the most striking feature of the emerging crisis is the apparent shift in alliances. During the Tigray War, Eritrea fought alongside Ethiopia against the TPLF. Now, however, reports suggest that Asmara may be quietly supporting Tigrayan forces, an alliance of convenience born of shifting strategic interests.
The reasons are not difficult to discern. In the years since the war, Abiy Ahmed has increasingly emphasized Ethiopia’s need for direct access to the sea, a goal that has raised alarms in Eritrea. Ethiopian officials have discussed the possibility of securing access to the Red Sea port of Assab, currently under Eritrean control, while Addis Ababa has also pursued controversial agreements with Somaliland aimed at securing port access. For Eritrea’s leadership, such developments understandably evoke fears of territorial encroachment.
As a result, Eritrea appears to be hedging its bets. Diplomatic contacts between Eritrean officials and TPLF representatives have reportedly increased, while Eritrean forces have maintained positions along key routes in northern Ethiopia. If this alignment solidifies, the next conflict in Tigray could evolve from an internal Ethiopian struggle into a broader interstate confrontation.
The risk of escalation is heightened by Ethiopia’s own internal fractures. The federal government continues to battle insurgencies in several regions, most notably in Amhara, where armed Fano militias have mounted a persistent challenge to federal authority. These overlapping conflicts strain the capacity of the Ethiopian National Defense Force and raise the possibility that any renewed war could quickly expand into a multi-front struggle.
A wider regional dimension cannot be ruled out. The Horn of Africa already sits amid a web of geopolitical rivalries involving Egypt, Sudan, and the Gulf states, many of which have strategic interests tied to the Red Sea and the disputed waters of the Nile. The ongoing conflict in Sudan and the broader instability affecting Red Sea shipping lanes only heighten the stakes.
Panning out, then, the drivers of the crisis are hardly mysterious: unresolved territorial disputes, internal political rivalries, and the persistent temptation among governments to use military force as an instrument of policy. Abiy’s centralizing ambitions collide with Tigrayan demands for autonomy, while Eritrea’s leadership remains deeply suspicious of Ethiopia’s long-term intentions.
Yet as history repeatedly demonstrates, wars born of such calculations rarely produce the stability their architects promise. The previous Tigray conflict unleashed widespread atrocities, massacres, sexual violence, and ethnic cleansing, while leaving vast areas economically devastated. Renewed fighting would likely deepen food insecurity across northern Ethiopia, where millions remain dependent on humanitarian assistance.
The economic consequences would also be severe. Ethiopia’s economy already faces mounting pressures from inflation, rising debt, and ongoing insurgencies. Another major conflict could further erode investor confidence and divert scarce resources away from development and reconstruction. Eritrea, meanwhile, remains one of the world’s most heavily militarized societies, sustained in part by indefinite conscription and a highly centralized state apparatus.
External powers have called for restraint, but their ability, or willingness, to influence events appears limited. Western governments remain preoccupied with crises elsewhere, while regional diplomacy has struggled to bring all relevant actors to the table. Without sustained political engagement, the diplomatic framework established in Pretoria risks gradually eroding.
War is not inevitable. Diplomatic pathways remain open: renewed mediation that includes Eritrea, confidence-building measures such as troop withdrawals, and serious efforts to implement the provisions of the Pretoria agreement. But such steps require political will, and at present that will appears in short supply.
The tragedy of the Horn of Africa is that its people have endured decades of conflict, yet the lessons of those experiences often go unheeded by those in power. Once again, the region stands at a crossroads between escalation and restraint. Should its leaders choose the former, the result will not be victory or stability, but simply another chapter in a long and painful cycle of war.
