Aksum, Adulis and the Red Sea Trade
The Eritrean coast and highlands lay at the heart of the Kingdom of Aksum, whose port of Adulis linked Africa to Rome, Arabia and India.
From around the first century CE the Kingdom of Aksum rose across the northern highlands of present-day Eritrea and Ethiopia to become one of the great trading powers of the ancient world. Its outlet to the sea was Adulis, on the Gulf of Zula near modern Massawa, named in the first-century Greek navigational manual the Periplus of the Erythraean Sea as a regulated port where Aksumite authorities controlled commerce. Through Adulis flowed ivory, gold, incense, tortoise shell and other African goods bound for Roman Egypt, South Arabia, Persia and India, and in return came cloth, metalware, wine and glass.
Adulis made Aksum a maritime as well as a highland power, and a contemporary writer ranked the kingdom alongside Rome, Persia and China. Aksumite kings minted their own gold, silver and bronze coinage and, in the fourth century, adopted Christianity, an identity that endured long after the kingdom's political eclipse. The coast and the Dahlak Archipelago offshore were stitched into a wider Red Sea and Indian Ocean world whose currents of trade, faith and language would shape the region for centuries.
From the late sixth and seventh centuries Aksum declined. Shifting trade routes, the exhaustion of resources and, above all, the rise of Islam along the opposite Arabian shore drew commerce away from Adulis, which fell into obscurity. Its ruins, near the Eritrean coast, were rediscovered and excavated by European and later Eritrean and British archaeologists, and remain a touchstone of Eritrea's claim to one of Africa's oldest civilisations.
“Adulis was the principal seaport of the Aksumite kingdom, a gateway through which Africa traded with Rome, Arabia and India.”

The Beja, the Dahlak Sultanate and the Muslim Coast
After Aksum, the coast became a Muslim-dominated trading world of the Beja, the Dahlak Islands and the rising port of Massawa, set against the Christian highlands.
As Aksum waned, the Eritrean lowlands and coast passed into the orbit of the Cushitic-speaking Beja, whose semi-nomadic confederacies dominated the caravan routes and coastal trade from around the eighth century. The offshore Dahlak Archipelago became a centre of Red Sea commerce, and with the rise of the Sultanate of Dahlak from the eleventh century its rulers controlled the exchange between the Muslim coast and the Christian highlands, profiting from pearl fisheries and the trade in goods and enslaved people.
Massawa, sheltered by its islands, gradually overtook the older harbours and grew into the chief link between the interior and the wider Indian Ocean world. The peoples who make up modern Eritrea took shape across these centuries: the Tigrinya-speaking Christians of the highlands, the Tigre and Beja of the northern lowlands, and the Afar and Saho of the coast and southern deserts, alongside Bilen, Kunama, Nara and others. The highland Christian polity of Medri Bahri ('land of the sea') emerged to contest the coast with these lowland and Muslim powers.
Islam, carried across the narrow sea, became deeply rooted along the coast and in the lowlands even as the highlands remained a stronghold of Orthodox Christianity, a religious geography that still defines Eritrea. The era closed when a new imperial power reached the Red Sea: in 1557 Ottoman forces seized Massawa, ending the long age of local and dynastic control of the coast.

Ottomans, Egyptians and the Contested Coast
For three centuries the Red Sea coast was ruled at arm's length from Constantinople and Cairo, while the highlands stayed beyond imperial reach.
From 1557 the Ottomans held Massawa, the Dahlak Islands and stretches of the coast as part of their Habesh province, governing through local agents and exacting customs on the Red Sea trade. Ottoman power on this far frontier was always thin, and real control over the harbours often rested with hereditary local rulers, the naibs of the Massawa region, who balanced between the empire, the highland Christian kingdom and the lowland peoples of the interior.
In the nineteenth century, as Ottoman authority faded, Egypt under its ambitious Khedives extended its reach down the African Red Sea coast. Egyptian forces took over the administration of Massawa, holding it from the 1860s into the 1880s and pressing inland toward the highlands, where they clashed with the Ethiopian empire. Egyptian rule entrenched the coast's role as a customs and garrison zone but never absorbed the highland interior.
By the 1880s Egypt, bankrupt and convulsed by the Mahdist revolt in Sudan, withdrew from the coast. The vacuum it left on this strategically vital shore, opposite the newly opened Suez Canal route, drew in a new and far more permanent power. Italy, already established at the port of Assab, moved to occupy Massawa in 1885, setting the stage for the creation of a single colony out of the patchwork of coast and highland.

Italy's First-Born Colony
Italy proclaimed Eritrea its colonia primogenita in 1890, built Asmara into a modernist capital, and used the territory as the base for its wars on Ethiopia.
On 1 January 1890 Italy formally united its Red Sea possessions into a single colony, Eritrea, named from the Latin for the Red Sea (Mare Erythraeum). It was promoted as Italy's colonia primogenita, the 'first-born colony', and held a larger Italian settler population than Rome's later acquisitions in Somalia and Libya. The colonial capital, first at Massawa, was moved up to the cooler highland town of Asmara in 1897, which over the following decades was rebuilt as a planned modernist city of cinemas, garages and rationalist and Art Deco buildings, later inscribed by UNESCO as 'Asmara: A Modernist City of Africa'.
Eritrea served above all as the military springboard for Italian designs on Ethiopia. Pushing south from the colony, an Italian army was annihilated by Emperor Menelik II at the Battle of Adwa on 1 March 1896, the most crushing defeat of a European force in Africa, which fixed Eritrea's southern border and checked Italian ambitions for a generation. Italy invested in roads, the highland railway to Asmara and Massawa, plantations and industry, but ruled through land confiscation, forced labour and a rigid racial segregation that subordinated Eritreans while recruiting tens of thousands of them as colonial soldiers, the ascari.
Under Fascism the colony's military role returned. In October 1935 Mussolini launched the conquest of Ethiopia from Eritrea, and after Adwa and Aksum fell and Addis Ababa was taken in May 1936, Eritrea was folded into Italian East Africa. The empire was short-lived. In the Second World War, British, Commonwealth and Free French forces broke Italian resistance at the long Battle of Keren in early 1941; Asmara and Massawa surrendered, and half a century of Italian rule ended.
“Asmara is an exceptionally well-preserved example of a colonial planned city, resulting from successive phases of planning between 1893 and 1941 under Italian occupation.”

Federation, Annexation and the Thirty-Year War
British administration gave way to a UN federation with Ethiopia in 1952; its abolition in 1962 ignited a thirty-year war of independence.
British military administration governed Eritrea from 1941 while the Allies and then the new United Nations debated its fate. In 1950 the UN General Assembly resolved, as an American-backed compromise between full independence and union with Ethiopia, that Eritrea should become an autonomous unit federated with Ethiopia under the Ethiopian crown. The federation took effect on 11 September 1952, leaving Eritrea its own parliament, flag and control of domestic affairs within an Ethiopian-led union.
Emperor Haile Selassie steadily hollowed out that autonomy, banning Eritrean parties and newspapers, imposing Amharic and replacing Eritrean symbols. In November 1962 his government had the Eritrean assembly dissolve the federation, annexing Eritrea as an Ethiopian province. By then armed resistance had already begun: on 1 September 1961 Hamid Idris Awate and a small band of the Eritrean Liberation Front fired on Ethiopian forces, opening a war that would last three decades.
Through the 1970s leadership of the struggle passed from the ELF to the more disciplined, Marxist Eritrean People's Liberation Front. The conflict ground on through Haile Selassie's fall, the rise of Ethiopia's Marxist Derg under Mengistu, massive Soviet-backed offensives and recurrent famine. The EPLF dug into the northern mountains, ran its own clandestine administration and, from the late 1980s, went onto the offensive. In May 1991, as the Derg collapsed, EPLF fighters entered Asmara on 24 May, winning de facto independence after one of Africa's longest wars.
“Eritrea was to constitute an autonomous unit federated with Ethiopia under the sovereignty of the Ethiopian Crown.”

Chapter 06 · 1991 - present
Independence, Border War and the Closed State
A 1993 referendum brought formal independence; a devastating border war with Ethiopia and decades of one-party rule have left Eritrea among the world's most closed states.
The EPLF translated victory into statehood through the ballot. In a UN-monitored referendum held on 23-25 April 1993, Eritreans voted overwhelmingly for independence, reported at nearly unanimous approval on a high turnout. On 24 May 1993 Eritrea formally declared itself sovereign and, within days, joined the United Nations as its 182nd member. Isaias Afwerki, the EPLF's wartime leader, became president, and the movement reconstituted itself as the ruling People's Front for Democracy and Justice.
Hopes of a democratic dividend faded. A ratified constitution was never implemented, promised elections were never held, and dissent was crushed. The fragile peace with Ethiopia broke down over the contested border town of Badme, igniting a full-scale war from May 1998 to June 2000 that killed an estimated tens of thousands on each side and displaced more than a million people. The Algiers Agreement of December 2000 ended the fighting and a boundary commission awarded Badme to Eritrea, but Ethiopia refused to withdraw, leaving a tense 'no war, no peace' stand-off.
Citing that unresolved confrontation, the government entrenched one of the world's most repressive systems: open-ended national service, severe restrictions on movement, press and religion, and no independent courts or legislature, conditions documented by United Nations investigators and Human Rights Watch and driving large numbers of Eritreans into exile. A surprise rapprochement came in July 2018, when Isaias Afwerki and Ethiopia's new prime minister Abiy Ahmed signed a peace declaration formally ending the border war. Yet little changed internally, and Eritrea has remained a tightly closed, single-party state.
“Eritrea has no constitution in force, no national legislature, no independent press and no elections; national service for many is open-ended.”
