Asmara at the Center: Eritrea and the Collapse of the Old Horn of Africa Order

By Dawit Gebremichael Habte

Introduction

For more than eighty years, the Horn of Africa has been organized around a single geopolitical assumption: that Ethiopia was the indispensable center of regional order and that the security of the Red Sea could be managed through Addis Ababa. This assumption shaped the policies of superpowers, international organizations, and regional actors alike. It justified the sacrifice of Eritrean self-determination during the federation era, rationalized decades of support for Ethiopian regional primacy, and informed Washington’s broader strategy from the Cold War through the War on Terror. Today, that assumption is collapsing.

The convergence of multiple crises, the militarization of the Red Sea, the disruption of global shipping lanes, the rise of non-state actors capable of threatening maritime commerce, the closure of strategic chokepoints, and Ethiopia’s growing internal instability, has exposed a geopolitical reality long obscured by ideology and habit: the security of the Red Sea cannot be guaranteed from a landlocked capital hundreds of kilometers from the coast. Geography, which policymakers spent decades trying to circumvent, has reasserted itself with undeniable force.

As global powers search for reliable anchors in an increasingly volatile maritime environment, strategic attention is shifting toward the state that sits astride the western shore of the Red Sea and overlooks the approaches to Bab al-Mandeb. The same Eritrea that was once treated as a problem to be managed, isolated, or contained is emerging as a pivotal actor in the evolving architecture of regional security.

This is not merely a story about Eritrea. It is a story about the collapse of an old geopolitical order and the emergence of a new one. It is a story about how geography ultimately defeated political convenience, how sovereignty outlasted coercion, and how a nation long dismissed as peripheral has moved steadily toward the center of one of the world’s most consequential strategic theaters.

The road to this moment began not in the contemporary Red Sea crisis, but more than a century and a half ago, when the opening of the Suez Canal transformed the strategic value of a coastline that would repeatedly become the object of imperial ambition, international rivalry, and national struggle.

From Proxy to Pivot: The Reversal of Regional Strategy

For decades, external powers approached the Horn of Africa through an Ethiopia-centered framework. Washington, in particular, viewed Ethiopia as the principal vehicle through which it could advance its strategic interests in the region, whether during the Cold War, the struggle for influence in the Middle East, or the post-9/11 War on Terror. Within this framework, Eritrea was often treated not as an independent strategic actor but as a variable to be managed in service of broader geopolitical objectives.

This approach was evident as early as the federation era. American support for the arrangement that linked Eritrea to Ethiopia was influenced not only by diplomatic considerations but also by the strategic importance of Kagnew Station in Asmara, one of the most valuable communications and intelligence facilities in the world at the time. As Ethiopia consolidated control over Eritrea and ultimately annexed it in 1962, geopolitical priorities frequently outweighed concerns about Eritrean self-determination.

The same logic persisted long after Eritrea regained its independence. For much of the post-Cold War era, Washington continued to rely on Ethiopia as its preferred regional partner, investing heavily in Addis Ababa’s role as a security provider, extraordinary rendition, base for “enhanced interrogation” (systematic torture of detainees by the CIA), drone bases, and as an attack dog in Somalia, while viewing Eritrea largely through the lens of containment, sanctions, and diplomatic isolation.

By 2026, however, the assumptions underlying this strategy had begun to unravel. The growing instability within Ethiopia, combined with escalating threats to maritime navigation in the Red Sea, exposed the limitations of relying on a landlocked state to secure one of the world’s most critical maritime corridors. The challenge posed by Houthi attacks, Iranian influence, and broader regional insecurity increasingly shifted attention away from inland power projection and toward the states that physically control access to the Red Sea.

In this environment, Eritrea’s significance derives not from ideology or alliance politics, but from geography and state capacity. Its long Red Sea coastline, proximity to Bab al-Mandeb, and relative internal stability have made it an increasingly important factor in regional security calculations. What is emerging is not simply a change in diplomatic posture but a broader strategic reassessment, one that reflects the growing recognition that the future security of the Red Sea depends as much on the western shore as it does on the political calculations of the interior. Eritrea, once viewed primarily as an object of policy, is increasingly being recognized as a central participant in shaping the region’s strategic future.

The Forging of a Nation-State: 1869–1890

The origins of modern Eritrea followed a pattern familiar across much of colonial Africa. European explorers, missionaries, traders, and imperial agents arrived in lands already inhabited by established societies, negotiated or seized footholds, and gradually transformed those acquisitions into colonial possessions. Communities that had governed themselves for centuries suddenly found themselves reclassified as subjects of distant European powers.

The chain of events that led to the creation of Eritrea as a colonial entity began in the context of two transformative developments of the nineteenth century: the opening of the Suez Canal and the political unification of Italy. Seeking a foothold along the strategically important Red Sea corridor, Italy turned to a young Catholic missionary and explorer, Giuseppe Sapeto, to advance its interests in the region. The Suez Canal officially opened on 17 November 1869, dramatically increasing the strategic value of the Red Sea. Two days earlier, on 15 November 1869, Sapeto had concluded an agreement with local authorities in the Assab area on behalf of the Italian shipping company Rubattino, acquiring a parcel of coastal territory near the present-day port of Assab.

What began as a commercial acquisition gradually evolved into a colonial project. In 1882, Rubattino transferred its holdings to the Italian state, which assumed direct administration of the territory and formally declared Assab an Italian colony. This initial foothold enabled Italy to expand its presence along the Red Sea coast, culminating in the occupation of Massawa in 1885. Five years later, on 1 January 1890, Italy officially proclaimed the Colony of Eritrea, the first colony of the newly unified Italian kingdom.

A defining feature of this colonial enterprise was the creation of a single administrative unit from historically distinct political and cultural regions. The new colony incorporated the Beja-inhabited territories of the western lowlands, the highland polity of Medri Bahri, and the autonomous Afar sultanates stretching along the Red Sea coast. Although these regions possessed different political traditions, social structures, and historical experiences, Italian colonial administration brought them together within a common territorial framework. Over time, that framework would evolve into the territorial boundaries and political identity of modern Eritrea.

Federation and the Struggle for Sovereignty: 1941–1991

Following the defeat of Italian forces in 1941, Eritrea entered a period of uncertainty that should have culminated in independence, as was the expectation for many former colonies after the Second World War. Instead, the territory was placed under the British Military Administration (BMA). During this period, various external powers debated Eritrea’s fate with little regard for the wishes of its inhabitants. Among the proposals considered was the Bevin-Sforza Plan, which envisaged partitioning Eritrea by attaching the western lowlands to Sudan and incorporating the highlands and southeastern regions into Ethiopia. Although this partition scheme ultimately failed, it reflected a broader pattern in which Eritrea’s future was treated as a matter for external negotiation rather than the exercise of Eritrean self-determination.

In 1952, the partition proposal was replaced by a United Nations-imposed federation between Eritrea and Ethiopia. While presented as a compromise, the arrangement primarily satisfied Ethiopia’s longstanding desire for access to the Red Sea and failed to honor the aspirations of many Eritreans who sought full independence. The federation nevertheless served as a temporary barrier against the immediate dismemberment of Eritrea. That protection proved short-lived. Through a systematic process of erosion, Ethiopia dismantled the federal arrangement and, in 1962, formally annexed Eritrea in violation of the federal covenant and the principles upon which it had been established.

The annexation ignited one of Africa’s longest and most determined armed liberation struggles. For thirty years, Eritreans fought to reclaim their right to self-determination, decolonization and national sovereignty. The struggle reached its culmination in May 1991, when Eritrean forces liberated Asmara, the capital city, and defeated the last major Ethiopian garrison at Assab. The victory not only ended decades of war but also affirmed the territorial integrity and sovereign identity of Eritrea. Assab, where the colonial story of Eritrea had begun more than a century earlier, emerged as a powerful symbol of national unity and is often regarded as the cradle of Eritrean national identity and a cornerstone of Eritrea’s sovereign statehood.

The Global Strategic Chokepoint

Historically, Eritrea has not been just a local territory but a critical node in global geopolitics. During World War II, its high-altitude airfields became some of the busiest Allied air bases in Africa. During the Cold War, Eritrea hosted Kagnew Station, a vital US communications and intelligence facility used for monitoring Soviet missile and space telemetry. The US Joint Chiefs of Staff noted in 1948 that “the benefits now resulting from operation of our telecommunications center at Asmara—benefits common and of high military importance to both the United States and Great Britain—can be obtained from no other location in the entire Middle East-Eastern Mediterranean area.”

Eritrea’s role as a global strategic chokepoint is further underscored by its proximity to the Suez Canal-Red Sea corridor, a maritime lifeline that has faced repeated disruptions in the modern era. While the nation served as a vital node during the Cold War, the surrounding region remains a persistent arena of confrontation where maritime accidents and geopolitical strife have global consequences. 

The strategic fragility of this maritime corridor has been demonstrated repeatedly in modern times. In late 2004, the 9,000-ton Kuwaiti oil tanker Al-Samidoun collided with one of the canal’s piers and ran aground in the Suez Canal, cracking its hull and spilling an estimated 10,000 cubic meters of oil into the waterway before salvage operations could stabilize the vessel. Nearly two decades later, the world witnessed an even more dramatic reminder of the canal’s vulnerability when the giant container ship Ever Given ran aground in March 2021, lodging itself across the canal and bringing one of the world’s most important trade arteries to a standstill for six days. At the height of the COVID-19 pandemic, the blockage disrupted global supply chains and halted an estimated $9.6–10 billion in trade every day.

These incidents underscored a reality long understood by empires, strategists, and maritime powers: a disruption at one narrow chokepoint can reverberate across the global economy. They also highlight why control and security of the Red Sea corridor have remained matters of immense geopolitical significance. The same strategic calculations that made the region indispensable to global commerce today are the ones that, in earlier eras, made Eritrea’s coastline a prized objective for competing imperial powers seeking to dominate the shortest and most lucrative sea route linking Europe and Asia.

The nation now serves as a primary observer of a new era of maritime instability, particularly during the Red Sea shipping crisis of 2023–2026. The wave of Houthi missile and drone strikes against commercial vessels bound for the Suez Canal forced a massive redirection of trade around the Cape of Good Hope, causing the volume of goods passing through the canal to drop by 50 percent in early 2024. These modern disruptions reaffirm that Eritrea remains the geographic anchor of a region where local conflicts and maritime chokepoints, such as the Bab el Mandeb Strait, can rapidly transform into global economic shocks.

Eritrea and the New Red Sea Security Architecture

In May 2026, a sweeping strategic realignment seems to unfold across the Red Sea driven by strategic realism. The closure of the Strait of Hormuz and the simultaneous threat to the Bab al-Mandeb by Houthi insurgents have rehabilitated Eritrea’s value as the primary western coast anchor for maritime security. In a major policy reversal, the Trump administration moved to normalize ties with Asmara, proposing to lift long-standing sanctions in exchange for cooperation in monitoring regional threats.

This new security architecture positions Eritrea as a central provider of regional order. This realignment reflects the growing strategic value of Eritrea, whose centralized and inclusive governance offers a level of stability and strategic predictability rare in a region marked by proxy-driven fragmentation, while its navy provides a critical baseline of stability and order in the southern Red Sea.

A Nexus of Vulnerability and Potential

The current model accepts Eritrea because its geography has become too valuable to ignore. From the first coaling stations at Assab to the electronic listening posts of the Dahlak Archipelago, Eritrea’s coastline remains the definitive barometer of Red Sea power. For global trade and energy markets, the stability of the entire corridor now hinges on the centralized choices made in Asmara.

The 2026 rapprochement signals the definitive collapse of the traditional US strategy of managing the Horn through an Ethiopian client-state proxy. While Washington once subsidized Addis Ababa’s regional dominance to safeguard the flow of trade toward the Suez Canal, the simultaneous closure of the Strait of Hormuz and the Bab-el-Mandeb has made Eritrea’s 1,100-kilometer coastline too valuable to remain under the shadow of its neighbor. Ultimately, the future of global energy markets and the security of the Suez Canal no longer flow through the political channels of Addis Ababa but rely on the choices made in Asmara.

Conclusion

History often moves slowly until it moves all at once. For much of the twentieth century and the opening decades of the twenty-first, the dominant powers of the international system attempted to manage the Horn of Africa through an Ethiopia-centered framework. Eritrea was expected to adjust to that reality, accommodate it, or disappear beneath it. Yet the strategic assumptions that sustained this order have steadily unraveled. Geography, maritime commerce, military necessity, and regional instability have combined to expose the limitations of a model built around a landlocked proxy while overlooking the state that controls one of the most strategic coastlines in the world.

The transformation underway is therefore more profound than a simple diplomatic rapprochement or a temporary shift in policy. It represents the gradual recognition of a geopolitical fact that history repeatedly affirmed but policymakers often ignored: the Red Sea cannot be secured without Eritrea, and the Horn of Africa cannot be understood without Asmara.

From the acquisition of Assab in 1869 to the liberation of Eritrea in 1991, from Kagnew Station to the contemporary Red Sea crisis, Eritrea’s history has been inseparable from the struggle to control one of the world’s most important maritime corridors. What has changed is not Eritrea’s geography, but the willingness of external actors to acknowledge its significance.

The old order was built on the belief that power flowed from Addis Ababa toward the sea. The emerging order is increasingly shaped by the recognition that stability, maritime security, and the uninterrupted flow of global commerce depend on the western shore of the Red Sea itself. In that reality, Eritrea is no longer a peripheral actor standing at the edge of regional politics. It has become one of the central pillars upon which the future security architecture of the Red Sea will rest.

The collapse of the old Horn of Africa order is therefore not merely the story of a declining geopolitical framework. It is the story of a strategic center of gravity returning to where geography placed it all along: Asmara.
