For more than a century, scholars and explorers have sought to locate one of ancient Egypt’s most enigmatic lands: the fabled Kingdom of Yam. Mentioned in the tomb inscriptions of Harkhuf, Governor of Elephantine during the Sixth Dynasty, Yam was once a source of Egypt’s most prized luxuries, including ivory, leopard skins, ostrich feathers, ebony, and fragrant incense. Yam vanished abruptly from the written record more than 4,000 years ago, after the end of the Middle Kingdom – its location and fate shrouded in mystery. But now a remarkable discovery deep within the Sahara Desert may finally bring this lost land back into focus. The find not only links modern exploration with the journeys of one of history’s earliest recorded travellers, but also offers the first tangible clue to the possible whereabouts of this lost kingdom.

Harkhuf: the world’s first recorded explorer 

Harkhuf lived in the Sixth Dynasty during the reigns of Merenra (c.2287 2278 BC) and Pepy II (c.2278-2184 BC). As Governor of Elephantine (modern-day Aswan), he held a crucial position on Egypt’s southern frontier. His responsibilities extended beyond local administration. He was the overseer of long-distance desert expeditions, and a trusted royal envoy, leading caravans deep into Africa in search of trade, alliances, and rare treasures. His most significant destination was the distant and little-known land of Yam.

On the walls of his tomb at Qubbet el-Hawa, overlooking the Nile’s First Cataract, Harkhuf recorded his achievements in detailed hieroglyphic inscriptions – one of the earliest autobiographical texts in human history. These texts recount four major expeditions to the mysterious Kingdom of Yam, each more ambitious than the last. In his own words, Harkhuf’s first great mission was to ‘explore a road to this country’ and open a route to Yam. The expedition, undertaken with his father Iry, was ordered directly by the king, as Harkhuf proudly recounts: 

The majesty of Merenra, my lord, sent me, together with my father, the sole companion, ritual priest Iry, to Yam, in order to explore a road to this country.

The journey, through untamed desert and unknown lands to the south of Egypt, took seven arduous months. When he finally returned, Harkhuf recorded that he came back ‘with all kinds of gifts’ and was ‘greatly praised’ for his success. Whether these treasures were secured through trade, diplomacy, or royal authority remains uncertain. What is clear is that Yam had become a respected and valued partner of Egypt.

Expeditions through unknown lands

On his second expedition, Harkhuf set out alone, determined to build on his earlier success. This time he chose a different path, following what he called the ‘Elephantine Road’, a route that wound through the regions of Irtjet, Mekher, and Terers. His inscription underscores both the magnitude and the triumph of the venture. He recorded that the journey lasted eight months, and that the gifts he presented to his king were so extraordinary that ‘never before was the like brought to this land’. The words convey not only the richness of the trade, but also the endurance, courage, and organisation demanded by such an undertaking.

Beyond the exchange of goods, the account reveals Harkhuf’s growing stature as a pioneer and pathfinder. He was mapping uncharted territory, establishing safe caravan routes, collecting valuable intelligence about Egypt’s southern frontiers, and exploring the lands of Irtjet and Setju. With justifiable pride, he boasts that ‘never had any companion or caravan conductor who went forth to Yam before this, done it’. With each expedition, Harkhuf expanded the limits of the known world and deepened Egypt’s reach into the heart of Africa.

By his third journey, Harkhuf had become deeply familiar with the desert routes and the peoples who inhabited them. He set out along the ‘Uhet Road’ (possibly the Oasis Road running westward towards Kharga and Dakhla), a path that crossed some of the most-challenging terrain of Egypt’s western frontier. During this expedition, he encountered the Chief of Yam, who was then leading a campaign against a land called Temeh (the Libyans of the Western Desert and beyond). Harkhuf notes simply, ‘I pacified him until he praised all the gods for the king’s sake’ – a brief but revealing line that shows his tact and authority in tense circumstances.

His growing knowledge of the lands of Irtjet, Setju, and Wawat (Lower Nubia), which at times turned hostile toward Egypt, gave him an advantage few others possessed. He proudly observed that ‘when the Chief of Irtjet, Setju, and Wawat saw how strong and numerous was the troop of Yam which descended with me to the court’, they respected both his power and his mission. Harkhuf’s caravan returned laden with incense, ebony, grain, panther skins, and ivory – clear evidence that his expanding routes had opened the way for long-distance trade deep into Africa.

By the time of Harkhuf’s fourth journey, the throne had passed to Pepy II, the young son of Merenra, who ascended to power while still a child. During this expedition, Harkhuf brought back a rare pygmy from Yam, described in his inscription as a ‘dancer of the gods’. When news of this remarkable find reached the palace, the boy-king was filled with excitement. He sent Harkhuf a letter brimming with affection and detailed instructions for the pygmy’s safe transport. Pepy urged him to take every precaution on the journey north, ensuring that the dancer would neither fall nor tire, and promised Harkhuf rich rewards on his return. The royal letter, which was carved into the walls of Harkhuf’s tomb, is one of the most human and touching texts of the Old Kingdom. It captures a moment of youthful wonder and a king’s fascination with the distant lands explored in his name. Harkhuf’s achievements are not only celebrated, but immortalised as symbols of Egypt’s curiosity and reach.

A kingdom lost in the sands of time

After Harkhuf’s time, the name of Yam gradually disappeared from Egyptian inscriptions, slipping quietly into legend. For decades, scholars have debated its true location. David O’Connor placed it somewhere in Nubia, near the ancient city of Kerma, in northern Sudan. Others, including Jean Yoyotte and Hans Goedicke, argued that Yam lay to the west beyond the Nile, deep within the Libyan Desert. 

Locating Yam is more than a matter of geography. Finding its position would reveal how far Egypt’s influence reached into Africa during the Old Kingdom, and how trade networks functioned in an era when the desert served both as a barrier and a bridge. The search for Yam is, therefore, also a search for the limits of Egyptian exploration and the nature of its early contact with the peoples of the African interior.

Was Yam a river kingdom on the edge of Nubia, or a desert realm lost among forgotten caravan trails? For generations, the evidence was frustratingly scarce, indirect, scattered across ancient texts and tomb walls, with no maps or detailed records to guide the search. However, many modern desert research expeditions have ventured into one of the most remote corners of the Sahara and uncovered several crucial discoveries that may, at last, shed light on Yam’s possible location.

The Abu Ballas Trail: Egypt’s forgotten desert highway

In 1917, a British desert patrol unit, the Light Car Patrol, discovered a hill with hundreds of earthen jars stored at its base. A few years later, in 1924, the Egyptian explorer Prince Kemal el-Din Hussein uncovered more than 300 large ceramic jars there. He named the place Abu Ballas, meaning ‘Father of Pots’. Ever since, Abu Ballas has been clearly marked on every map of the Western Desert as a major waypoint en route to the Gilf Kebir plateau (famous for its rock art), and yet for decades it stood as an isolated mystery, its purpose only partly understood. 

Decades later, in 2000, the German explorer Carlo Bergmann and other researchers identified a network of sites stretching between Dakhla Oasis and Gilf Kebir. Together, these finds outlined a 400-kilometre ancient caravan route now known as the ‘Abu Ballas Trail’ (ABT). The trail connected a chain of about 30 waystations spaced at regular intervals and marked by dense clusters of pharaonic pottery. These jars – some marked with distinctive potmarks – were traced to Ayn Asil (Balat) in Dakhla Oasis, revealing that the Abu Ballas site once served as a crucial logistical station for desert caravans. Such stations, called muhatta, functioned as water depots, providing water and supplies to travellers venturing far beyond the Nile Valley. Archaeological surveys have revealed the sophistication of this desert network. The waystations were linked by faint stone alignments and navigation markers called alamat, and in some places, the remains of stone huts and shelters offered protection against the harsh elements. The pottery assemblages found included large storage jars, drinking bowls, and straw-tempered vats for preparing bread dough.

Archaeological evidence reveals that the ABT was most active at the end of the Old Kingdom and into the First Intermediate Period, reflecting an era of organised exploration and long-distance trade. Its layout demonstrates an extraordinary feat of logistical planning in one of the most inhospitable environments on earth. Carlo Bergmann suggested that the ABT might have continued to Gebel Uweinat, but lacked firm evidence. However, in 2007, I was part of a team that made a remarkable discovery in that region: the Uweinat Inscriptions. These provided the first irrefutable proof that the ancient trail may indeed have reached the frontier once linked to the lost Kingdom of Yam.

Discovery at Gebel Uweinat

In November 2007, I led a month-long expedition with Maltese adventurer Mark Borda, travelling into the heart of the Western Desert – an area of immense beauty and isolation. 

Our destination was Gebel Uweinat, roughly 700 kilometres west of Abu Simbel, at the point where the borders of Egypt, Libya, and Sudan meet. Travelling across shifting sand plains and rugged plateaus, we faced extreme conditions. Temperatures soared by day and dropped sharply by night. The terrain was strewn with sharp ridges, ancient dry wadis, and dune fields. Water was rationed carefully, and vehicles had to be navigated through treacherous terrain of dunes and rocky escarpments.

It was here, amid this vast and silent wilderness, that we made a discovery of great archaeological importance. On a sandstone boulder, we found a group of hieroglyphic inscriptions unmistakably Egyptian in character, including the depiction of a king. 

The panel included:

(i) a cartouche naming King Mentuhotep II (Nebhepetra), the ruler who reunited Egypt and founded the Middle Kingdom c.2055 BC
(ii) a seated figure of the king, wearing the crown of Lower Egypt (to the left)
(iii) hieroglyphic references to two foreign lands: Yam and Tekhebet (on the right-hand side)

Although brief, the Uweinat Inscriptions carry profound implications. They provide undeniable evidence that Egyptian expeditions reached Gebel Uweinat as early as the Middle Kingdom. Moreover, the hieroglyphs directly link the site with the name ‘Yam’, the fabled kingdom described by Harkhuf thousands of years earlier. Clearly, the carvings portray a vivid scene of royal authority and the submission of distant lands. Two figures are depicted presenting offerings to Mentuhotep. One, a Yamite, lies prostrate in full submission, with another figure kneeling behind holding a container of incense. Below this, another man – representing the previously unknown province Tekhebet – kneels as he offers an oryx, perhaps symbolising livestock or a sacred animal. The incense from Yam and the offering from Tekhebet together evoke both material tribute and ritual devotion. The entire panel underscores the theme of obeisance and allegiance, echoing the classic iconography of conquered or tributary peoples within the Egyptian world order. These elements convey a message of Egyptian dominion over distant lands, both through trade and through the symbolic power of royal authority. Gebel Uweinat thus emerges not only as a remote outpost of contact, but also as a frontier where Egypt’s influence, religion, and political ideology reached deep into the desert.

Reflections on a lost kingdom

The discovery of the Yam Inscriptions at Gebel Uweinat has transformed the long-standing debate about Egypt’s reach into the deep desert, and challenged long-held assumptions about the limits of pharaonic influence. In addition, we now have for the first time palpable evidence that links a specific royal name, an identifiable location, and the fabled Kingdom of Yam mentioned in Harkhuf’s tomb.

Yet the find opens as many questions as it resolves. Was Uweinat itself part of Yam, or a northern outpost along its trade routes? Did Egyptian envoys venture even farther south into Darfur or beyond Uweinat, continuing the trajectory of the trail toward the Chad Basin? Following our discovery, scholars have proposed four possible locations for Yam beyond Uweinat. Rudolph Kuper and Frank Förster suggested Kufra (in present-day Libya) as a possible destination for the donkey caravans. In contrast, Carlo Bergmann believed the trail continued as far as Lake Chad, while Julien Cooper placed Yam in Darfur and farther south – or perhaps in the area between Uweinat and the Nile, which includes the Merga and Selima Oases (in present-day Sudan).

The discovery also reignited scholarly debate about the true extent of Yam. Some researchers view Uweinat as the heart of the lost kingdom, while others interpret it as a ceremonial meeting place where Egyptian envoys exchanged gifts with desert tribes. Most scholars, however, regard Yam as a non-localised region extending across vast distances, whereas Tekhbet(en) may have been the localised, central area around Uweinat Mountain. Whatever its precise role, the site reflects Egypt’s enduring ambition to explore, trade, and assert authority over the immense territories bordering its fertile lands. In 2013, with renowned Swiss photographer Hardy Böckli, I explored north-eastern Chad for eight weeks, tracing the desert’s ancient corridors. The expedition found no evidence that the ABT continued south west towards Lake Chad, suggesting that Yam may lie south of Uweinat, perhaps in Darfur or as far south as Central Africa, where pygmy tribes still exist. Sadly, political unrest in the region has delayed further exploration.

Theories and implications 

What is certain is that the inscriptions reveal the astonishing reach of Egyptian exploration more than a millennium before the great imperial expeditions of the New Kingdom. They show a civilisation that mastered the deserts, and forged enduring connections with the peoples who inhabited them. The ABT, which may have extended to Uweinat, could well represent the very ‘Oasis Road’ Harkhuf once described. Even the smallest details in Egypt’s material culture hint at the scale of this desert connection. For instance, the green scarab adorning King Tutankhamun’s pectoral was once thought to be ordinary stone, until scientists proved it was carved from Libyan Desert glass, formed in a remote part of the Great Sand Sea. Such discoveries remind us that the desert was never an empty expanse, but a living landscape woven into the story of Egypt itself.

The Uweinat Inscriptions stand, therefore, as more than a record of tribute or trade. They are a testimony to Egypt’s reach across the frontiers of geography and imagination, and they renew the ancient question that still challenges scholars and explorers alike: where, in the endless sands, lies the lost Kingdom of Yam?
