There is a question about the Horn of Africa that almost no one in the policy or analytical community is seriously working on, because the subject of the question operates a state so closed that serious work on it is nearly impossible. The question is this: what happens to Eritrea when Isaias Afwerki is gone? And the reason it matters beyond Eritrea itself is that the answer will reshape the security architecture of the entire region in ways that no government in the Horn, and no external power with interests there, is adequately prepared for.
Isaias Afwerki is eighty years old. He has been the singular leader of Eritrea since the country won its independence from Ethiopia in 1991, having led the Eritrean People's Liberation Front through a thirty-year armed struggle before that. He is in reasonable health by available accounts, but he is eighty, and the absence of any succession mechanism in the Eritrean state means that his death or incapacitation would be, in the most literal sense, a constitutional crisis in a country that has no constitution. It would be a political crisis in a country that has no political parties. It would be an institutional crisis in a country whose institutions were built to serve one man's will rather than to function independently of it.
Planning for this transition, such as it exists, is happening inside a small circle of military and intelligence figures whose identities, relationships, and relative influence are opaque to the outside world. That opacity is intentional and complete. Eritrea under Isaias is perhaps the most information-restricted country in Africa, with no independent media, no civil society organisations that function independently of the state, no diplomatic community with genuine access to the inner workings of the government, and no exile community with credible current knowledge of the political dynamics inside Asmara. Analysing the succession question means working almost entirely from inference, from the structure of incentives, and from what comparable transitions in comparable systems have historically produced.
What Isaias built, and why it cannot outlast him easily
The defining characteristic of Isaias's governance model is the deliberate destruction of any institution that could function as a power centre independent of his personal authority. This began in the early years of independence, when Eritrea had a constitution drafted and ratified, a national assembly created, and a governing party with a functioning central committee. Between 2001 and 2002, after a group of senior officials published an open letter criticising Isaias and calling for democratic reforms, he moved decisively to dismantle every institutional check that had survived independence. The constitution was shelved. The national assembly stopped meeting. Eleven of the reform movement's most prominent figures were arrested in September 2001, the same week as the September 11 attacks in the United States, ensuring that international attention was entirely elsewhere. Those eleven are believed to have died in detention, though their fate has never been officially acknowledged.
What replaced the institutional framework was a system of personalised rule in which the security apparatus reports directly to Isaias, the military's senior commanders are carefully managed through a combination of loyalty cultivation and periodic rotation designed to prevent any individual from building an independent base, and the ruling People's Front for Democracy and Justice functions as an administrative apparatus rather than a political institution with any genuine decision-making role. The PFDJ's senior figures derive their authority from proximity to Isaias rather than from any formal institutional position, which means their authority is entirely contingent on his continued presence.
This structure is extremely stable under a single authoritative leader and extremely fragile at the moment of transition. Exactly because no institution has been allowed to develop independent authority, there is no institution that can claim legitimacy in the absence of the leader who built it. Succession in such systems tends to take one of two forms: a managed transition in which the inner circle agrees on a successor before the leader's death and orchestrates a handover, or a fragmented competition in which multiple figures with military or security backing contest for control after the leader dies. The managed transition requires a level of institutional trust and coordination among Eritrea's senior figures that the structure of Isaias's rule has systematically prevented from developing.
The military as the only institution that matters
In the absence of functioning political institutions, the Eritrean Defence Forces are the only organisation with the coercive capacity and internal hierarchy to manage a transition. This places Eritrea's military commanders at the centre of any succession scenario, whether they want to be there or not.
The Eritrean military is large relative to the country's population, with estimates of active personnel ranging from 200,000 to 320,000 in a country of roughly 3.5 million. The national service system, which conscripts Eritreans into indefinite military or civil service, means that a substantial fraction of the adult population is formally within the military structure. This is both a source of coercive capacity and a source of significant tension: the indefinite national service system is the primary driver of Eritrea's massive emigration, which has seen hundreds of thousands of Eritreans, disproportionately young and educated, leave the country over the past two decades.
The senior military command includes figures who have served Isaias for decades and whose loyalty has been maintained through a combination of personal relationships, material benefits, and the straightforward calculation that Isaias's system has been good to those within it. But loyalty to a person is different from loyalty to a system, and the personal relationships that sustain the senior military command's cohesion under Isaias are not transferable to any successor. The question of which commander, or which coalition of commanders, the senior military would coalesce around is genuinely unclear, and that lack of clarity is itself a source of instability risk.
The military also has a generational dimension that the succession question has to account for. The senior commanders are largely figures of the liberation war generation, men who fought with the EPLF and whose political formation was in the Marxist-inflected nationalist movement of the 1970s and 1980s. Below them is a generation of officers who came of age entirely under the post-independence system, whose political formation is different, and whose relationship to the liberation war's ideology is more distant. The extent to which these generational cohorts share political interests and would cooperate in a transition is unknown.
Scenarios and their regional implications
A managed military succession, in which senior commanders agree on a figure to lead a transitional government and successfully maintain state cohesion through the transition, is the scenario most favourable to regional stability. It would likely produce a government that initially maintained Eritrea's existing foreign policy postures, including the alliance with Ethiopia that Isaias and Abiy Ahmed established in 2018, while consolidating internally. It might, over time, open the political system modestly, as the liberating pressure of no longer needing to maintain Isaias's specific political logic reduced some of the constraints on reform. This scenario requires a level of elite coordination that is difficult to achieve but not impossible: the senior military figures know each other well, have shared interests in stability, and understand that a violent succession would threaten all of them.
A fragmented succession, in which multiple figures or factions contest for control, carries significantly higher risks. Eritrea's military hardware and the state's coercive apparatus would become assets in a factional conflict rather than instruments of a functioning state. The indefinite national service system, which depends on a single authority structure to function, could collapse, releasing hundreds of thousands of men with military training and weapons into an uncertain environment. The country's already severe emigration would accelerate dramatically. Regional powers would face pressure to back one faction or another, importing the conflict into the broader Horn security architecture.
The most consequential regional implication of a fragmented Eritrean succession would be on Ethiopia. The Isaias-Abiy partnership has been one of the defining features of post-2018 Horn geopolitics, including critically in the Tigray war, where Eritrean military intervention was decisive and where Eritrean forces committed atrocities that have been extensively documented. A fragmented Eritrea would eliminate that partnership and potentially create a hostile or unpredictable neighbour on Ethiopia's northern border at a moment when Ethiopia is already managing insurgencies in Amhara and Oromia and a fragile peace in Tigray. The Tigray People's Liberation Front, politically weakened but not destroyed, has interests in Eritrean political change that would give it reason to attempt to influence any transition in its favour.
The Red Sea dimension cannot be separated from the succession question either. Eritrea's coastline, at over 2,000 kilometres including its islands, is one of the most strategically significant in the region. The UAE, Saudi Arabia, and other Gulf states have sought basing or access rights on Eritrean territory in recent years, with varying success. A post-Isaias Eritrea in which multiple factions compete for external support would see those external powers offering resources, recognition, and military backing in exchange for access, replicating in miniature the same external competition for influence that has made Sudan's civil war so difficult to resolve.
The exile question
Eritrea has a diaspora of several hundred thousand people, heavily concentrated in Ethiopia before 2018, and in European cities, Israel, and North America. The diaspora has historically been politically divided between those who support the Isaias government and those who oppose it, and the opposition diaspora has been further fragmented between groups with different political visions, regional affiliations, and personalities. The Eritrean opposition in exile has not managed to produce a credible unified leadership or political platform in three decades of trying, and there is no reason to expect that a succession crisis inside Eritrea would suddenly produce the coordination that exile politics has consistently failed to generate.
What the diaspora does represent, however, is a significant economic resource. Eritrean remittances, including the two percent diaspora tax that the PFDJ levies on overseas Eritreans in exchange for government services, are a major component of the Eritrean economy. A post-Isaias government would need diaspora remittances to function regardless of its political character, giving the diaspora a degree of economic leverage it has never been able to translate into political influence under the current system.
What the silence around this question costs
The analytical and diplomatic silence around Eritrea's succession question has a cost that is easy to ignore because it is not yet visible. No regional body has a contingency framework for Eritrean instability. The African Union, whose Peace and Security Council would be the natural institutional forum for managing a transition crisis, has no established relationship with Eritrea's government and no access to the political dynamics inside Asmara that would allow it to play a constructive role in a transition. The United States and European governments, which have sanctioned Eritrea and have minimal diplomatic presence in Asmara, are even further from being able to influence events constructively.
This is not entirely the outside world's fault. Eritrea's closure has been total enough that building the relationships and knowledge that responsible engagement would require has been essentially impossible. But the absence of engagement means the absence of preparation, and the absence of preparation means that when the transition comes, the international and regional response will be improvised under pressure rather than planned in advance. Improvised responses to succession crises in fragile states with large militaries and strategic geography have a poor historical track record.
The Horn of Africa in 2026 is a region managing multiple simultaneous crises: the Sudan civil war, the ATMIS handover in Somalia, Ethiopia's internal insurgencies, the Nile water dispute. Those crises absorb the attention and resources of every government and institution working on the region. Eritrea, because it is not currently in crisis, because it is closed enough that the trajectory toward crisis is invisible, and because thinking about it seriously requires engaging with uncertainty that cannot be resolved, keeps getting deferred. That deferral will eventually produce exactly the kind of crisis that could have been mitigated with earlier, sustained attention. The succession question is not a hypothetical. It is a near-certainty, and the Horn is not ready for it.
