The Kingdom of Aksum

The Kingdom of Aksum — the trading empire of the Ethiopian highlands and the Red Sea (c. 1st–7th century CE), raiser of the giant carved stelae, minter of its own coinage, the first sub-Saharan state to adopt Christianity under King Ezana, and keeper of the Ethiopian Ark of the Covenant tradition.

From the harbor at Adulis a cargo set out that the highland kingdom behind it had assembled from a thousand miles of interior: tusks of African elephant, rhinoceros horn, hippopotamus hide, tortoiseshell, obsidian, gold panned from the river gravels, and the resinous incense that the whole ancient Mediterranean burned before its gods. The ships that carried it ran north up the Red Sea to Roman Egypt and east to the coasts of Arabia and India, and they came back laden with glass and wine and pressed olive oil, with brass and iron and dyed Egyptian cloth. The polity that controlled both ends of that exchange — the inland city of Aksum, on the watershed of the Ethiopian plateau, and its outlet on the sea — became, within the first centuries of the common era, the dominant power of the southern Red Sea and one of the great kingdoms of late antiquity.

A mid-first-century Greek handbook for merchants, the Periplus of the Erythraean Sea, already knew the place. Its anonymous author, a trader out of Roman Egypt, describes Adulis as the gateway to a kingdom ruled inland from a town called Aksum, and names its sovereign Zoskales — a careful, acquisitive man, the Periplus says, and acquainted with Greek letters. That a regional king on the African shore read Greek is the first signal of what Aksum would be: not a Roman dependency, not a marginal hinterland, but a literate sovereign state plugged directly into the commercial bloodstream that ran from Alexandria to the spice ports of southern India.

The trade nexus and the rivals across the water

Aksum sat at a hinge. To its north lay the Mediterranean world of the Roman Empire and its later eastern continuation, the Byzantine Empire, whose insatiable appetite for ivory, incense, and the luxuries of the Indies the Red Sea route supplied. To its east, across a narrow strait, lay the incense kingdoms of South Arabia, among them Saba with its ancient ties to the Ethiopian highlands — the two shores of the Bab al-Mandab had shared script, deities, and dynasts since before Aksum’s rise. And beyond Arabia stood the other superpower of the age, Sasanian Persia, whose ambition to control the maritime road to India and China made the Red Sea a contested artery. The merchant-priestly culture of late pre-Islamic Iran — the world later remembered in the Sasanian-Iranian wisdom tradition — pressed on the sea-lanes from the Persian Gulf side, and the long Roman–Persian struggle for the eastern trade gave Aksum’s loyalties a strategic weight far beyond its size.

How that weight was reckoned by a contemporary is preserved in an unexpected witness. The prophet Mani, founder in third-century Mesopotamia of a missionary religion of Light and Darkness, set down in his teaching collection, the Kephalaia, a list of the four greatest kingdoms of the inhabited world. The first, he said, was the kingdom of Babylon and Persia; the second, the kingdom of Rome; the third, the kingdom of the Aksumites; the fourth, the kingdom of Silis — most often read as China. To a Mesopotamian seer scanning the powers of the earth around 250 CE, Aksum stood in the same rank as Rome and Persia. The judgment was not flattery. It was an accurate reading of who controlled the wealth of the southern seas.

The stelae

The clearest monument to that wealth still stands — and lies — on the northern edge of the capital. There the Aksumites quarried single shafts of granite, dressed them, and raised them over the tombs of their kings: the stelae of Aksum, the largest worked monoliths ever attempted by human beings. They are not abstract obelisks in the Egyptian manner. Their faces are carved to imitate tall buildings — storey upon storey of false windows and beam-ends, surmounted by a false door at the base, as though a multi-story palace of stone had been stood on end to mark the dead. The grandest of the standing shafts, traditionally called King Ezana’s Stele, rises more than twenty-three meters and is dressed to read as a nine-story tower.

Beside it lies the wreck of an ambition that overreached. The Great Stele, some thirty-three meters long and weighing in the region of five hundred tons, was the single most massive block of stone any society of the ancient world ever tried to set upright — and it failed. It shattered, almost certainly in the act of erection or soon after, and has lain broken across the field ever since, smashing a royal tomb beneath it in its fall. The stelae belong to the third and fourth centuries CE, to the pagan apex of Aksumite kingship, before the cross displaced the older symbols; they are royal funerary obelisks raised when the kings were still buried, not yet baptized. One of them, the so-called Rome Stele, had a second history: looted by Mussolini’s army in 1937 and re-erected in Rome near the Arch of Constantine, it was returned to Ethiopia in 2005 and raised again on its home ground in 2008. The whole field is held today as a place of continuing religious meaning, inscribed on the UNESCO World Heritage list in 1980 as a masterpiece of human creative genius.

The coinage

If the stelae proclaimed sovereignty to the sky, the coins proclaimed it to the world. Around the close of the third century, under the king Endubis, Aksum began to strike its own money — the first state in sub-Saharan Africa to do so, and one of only a handful anywhere in the world then minting in gold. The Aksumite mint produced in all three metals: gold for international exchange, silver and bronze for circulation closer to home. The gold pieces carried legends in Greek, the language of the Red Sea trade and of the markets the coins were meant to reach; many of the smaller denominations bore Ge’ez, the language of the kingdom itself. To mint gold inscribed in Greek, sized and weighted to slot into the monetary world of Rome, was a deliberate statement: Aksum dealt with the great powers as a peer that issued its own sovereign currency, not as a client paid in someone else’s.

The earliest coins bore a pre-Christian emblem at the king’s head — a disc and crescent, the sign of the older Aksumite cult. Then, in the reign of one king, that emblem changed, and the change records one of the decisive conversions of late antiquity.

Ezana, Frumentius, and the see of Alexandria

The king was Ezana, who ruled in the middle of the fourth century. His inscriptions, set up in stone at the capital, are trilingual — composed in Ge’ez, in the Old South Arabian (Sabaean) script that links Aksum to the Arabian shore, and in Greek for the wider world. The earliest of them invoke the war-god Mahrem, whom the Greek versions equate with Ares, and the celestial powers of the old religion. The latest abandon them entirely and call instead upon the Lord of Heaven, the one God, in language unmistakably Christian. Between the two stands a conversion, and on the coins the disc-and-crescent gives way to the cross — making Aksumite money among the earliest cross-bearing coinage struck anywhere on earth.

The agent of that change, in the tradition transmitted by the church historian Rufinus of Aquileia (who had it from an eyewitness), was a young Christian from Tyre named Frumentius. Shipwrecked or seized on the Red Sea coast as a boy, together with his companion Aedesius, Frumentius was carried to the Aksumite court and rose to a position of trust under the regency, quietly gathering the Christian merchants already trading in the kingdom. In time he traveled to Alexandria and laid the situation before its patriarch, Athanasius — the great defender of the Nicene definition of Christianity — who answered by consecrating Frumentius himself as the first bishop of Aksum. The Ethiopians remember him as Abba Salama, the Father of Peace, and as the first Abuna; and from that consecration the Ethiopian church received its presiding bishop from the patriarch of Alexandria — the Coptic see — for sixteen centuries, until the twentieth.

The act placed Aksum, at the moment of its baptism, inside one of the most charged controversies in the history of the faith. Athanasius had consecrated Frumentius; and Athanasius was the implacable opponent of Arius, the Alexandrian presbyter whose teaching that the Son was a creature, not co-eternal with the Father, had split the empire and provoked the Council of Nicaea. The Roman emperor Constantius II, who leaned to the Arian side, grasped at once where Aksum’s new bishop had come from. In a letter preserved by Athanasius himself, the emperor wrote to Ezana and his co-ruler, asking them to send Frumentius back to Alexandria to be examined by the Arian-installed bishop George — a polite demand that the African kingdom’s church be brought into line with the imperial party. Ezana did not comply. The first Christian state of sub-Saharan Africa entered the faith on the Nicene side and under the wing of the Coptic patriarchate, and there, in doctrine and in hierarchy, it stayed.

Kaleb and the war across the sea

Two centuries after Ezana, Aksum reached the height of its power and turned that power outward across the water. The occasion was a massacre. In the South Arabian kingdom of Himyar, in present-day Yemen, a king named Yusuf As’ar Yath’ar — remembered as Dhu Nuwas, a convert to Judaism — moved to break the Christian community in his realm and laid siege to the city of Najran, putting its Christians to death around 523. The killing reverberated through the Christian world; it is recorded in the Martyrdom of Arethas, named for the leader of the Najran community, and the historian Procopius reports its aftermath. The Aksumite king Kaleb, called Ella Asbeha, took up the cause as protector of his co-religionists across the strait — and as the master of a sea that Himyar’s hostility threatened to close.

With the backing of the Byzantine emperor Justin I, who saw in the African king a useful ally against Persian influence in the region and is said to have provided shipping, Kaleb launched a fleet across the Red Sea around 525, defeated and killed Dhu Nuwas, and installed a Christian Himyarite as his viceroy. For a moment the kingdom of the highlands ruled both shores of the Bab al-Mandab and stood as the Christian sentinel of the southern sea against Sasanian Persia. The moment did not hold: a general named Abraha soon seized Himyar for himself, and within a few decades the Persians took Yemen outright, ending Aksumite power on the Arabian side. But the campaign fixed Aksum in memory as a Christian kingdom willing to cross the sea for the faith, and it is woven into the Ethiopian national epic as a deed of the Solomonic line.

The Solomonic legend and the Ark

For the living church and people of Ethiopia, the deepest meaning of Aksum is not its coins or its conquests but its descent. The Ethiopian Orthodox Tewahedo tradition holds that the royal line of Ethiopia springs from the union of King Solomon of Israel and the Queen of Sheba — whom the tradition names Makeda — and that their son, Menelik, brought the Ark of the Covenant from Jerusalem to Aksum, where it has been kept ever since. The narrative is set down in the Kebra Nagast, the “Glory of Kings,” a Ge’ez epic compiled in its received form in the early fourteenth century, drawing on far older biblical and oral matter; it became the charter of the Solomonic dynasty that ruled Ethiopia until 1974. In Aksum the Ark is said to rest in a treasury beside the Church of Our Lady Mary of Zion, guarded by a single monk who alone may approach it. To the faithful of the Ethiopian Orthodox Tewahedo Church this is not legend but custody — the continuous keeping of the holiest object of the first covenant by the kingdom that received it.

The same religious gravity drew the world’s other faiths into Aksum’s story. When the earliest followers of Muhammad faced persecution in Mecca, tradition holds that the Prophet sent a group of them across the Red Sea to take refuge with the Christian king of Aksum, the Najashi, who sheltered them — the episode Muslims remember as the first emigration, and a reason that early Islam held the Ethiopian kingdom in singular regard. Aksum thus stands at a crossing of traditions: a Christian African state in the orbit of Coptic Egypt, neighbor to the Sabaean and Arabian world from which the later Arabic Hermetica and Islamic learning would rise, contemporary with the Gnostic and Manichaean currents that the same late-antique sea-roads carried.

The textual and scholarly record

The recovery of Aksum as history, rather than as scripture and legend, rests on a small but precise body of evidence read together. The foundational survey is Stuart Munro-Hay’s Aksum: An African Civilisation of Late Antiquity (Edinburgh University Press, 1991), still the standard reference on the kingdom’s chronology, coinage, and archaeology; it is complemented by David W. Phillipson’s Foundations of an African Civilisation: Aksum and the Northern Horn 1000 BC–AD 1300 (James Currey, 2012), which sets the kingdom in the deeper history of the highlands, and by G. W. Bowersock’s The Throne of Adulis: Red Sea Wars on the Eve of Islam (Oxford University Press, 2013) on the sixth-century clash with Himyar. The earliest external witness, the Periplus of the Erythraean Sea, is available in W. H. Schoff’s public-domain translation of 1912; the conversion narrative survives in the Ecclesiastical History of Rufinus, summarized in the Catholic Encyclopedia’s account of Edesius and Frumentius and in the Dictionary of African Christian Biography. The Solomonic charter, the Kebra Nagast, was Englished by E. A. Wallis Budge in 1922 as The Queen of Sheba and Her Only Son Menyelek, and its place in Ethiopian self-understanding is traced in the World History Encyclopedia’s study of Solomonic descent. The capital’s monuments are cataloged and protected as a UNESCO World Heritage Site, inscribed in 1980. Across these sources the same kingdom comes into focus from contrasting angles: the merchant’s ledger, the bishop’s chronicle, the king’s trilingual stone, and the epic of a people who never stopped being the kingdom’s heirs.

The disc and the cross both still mark the highland. In the fourteenth-century churches and the rock-hewn sanctuaries of the country that grew from Aksum’s root, the priests carry the tabot — the consecrated tablet that stands, in every Ethiopian church, for the Ark that Menelik is said to have brought home — out in procession at the feast of Timkat, and the people follow it down to the water as their kings once followed the line that the Kebra Nagast traced back to Solomon. The coins that named Ezana in Greek are dug from the same soil where that procession passes. In Aksum the empire of the southern sea and the covenant of the Ethiopian church are not two stories but one continuous keeping: each Timkat the tabot is carried out from the church of Mary of Zion and down to the water, in the same rite and on the same ground that the kingdom Mani ranked beside Rome had consecrated.
