Sheba, or Saba, was an ancient South Arabian kingdom that existed in Yemen before 275 CE. It likely began its existence between c. 1000 BCE and c. 800 BCE. Its inhabitants were the Sabaeans, who, as a people, were indissociable from the kingdom itself for much of the 1st millennium BCE. Modern historians agree that the heartland of the Sabaean civilization was located in the region around Marib and Sirwah. In some periods, they expanded to much of modern Yemen and even parts of the Horn of Africa, particularly Eritrea and Ethiopia. The kingdom's native language was Sabaic, which was a variety of Old South Arabian.
Among South Arabians and Abyssinians, Sheba's name carried prestige, as it was widely considered to be the birthplace of South Arabian civilization as a whole. The first Sabaean kingdom lasted from the 8th century BCE to the 1st century BCE: this kingdom can be divided into the "mukarrib" period, where it reigned supreme over all of South Arabia; and the "kingly" period, a long period of decline to the neighbouring kingdoms of Ma'in, Hadhramaut, and Qataban, ultimately ending when a newer neighbour, Himyar, annexed them. Sheba was originally confined to the region of Marib (its capital city) and its surroundings. At its height, it encompassed much of the southwestern parts of the Arabian Peninsula before eventually declining to the regions of Marib. However, it re-emerged from the 1st to 3rd centuries CE. During this time, a secondary capital was founded at Sanaa, which is also the capital city of modern Yemen. Around 275 CE, the Sabaean civilization came to a permanent end in the aftermath of another Himyarite annexation.
The Sabaeans, like the other South Arabian kingdoms of their time, took part in the extremely lucrative spice trade, especially including frankincense and myrrh. They left behind many inscriptions in the monumental Ancient South Arabian script, as well as numerous documents in the related cursive Zabūr script. Their interaction with African societies in the Horn is attested by numerous traces, including inscriptions and temples dating back to the Sabaean presence in Africa.
The Hebrew Bible references the kingdom in an account describing the interactions between King Solomon of Israel and a figure identified as the Queen of Sheba. The Hebrew Bible's account is considered legendary. A similar narrative is also found in the Quran (Sheba is distinct from the Sabians). Traditions concerning the legacy of the Queen of Sheba feature extensively in Ethiopian Christianity, particularly Orthodox Tewahedo, and among Yemenis today. She is left unnamed in Jewish tradition, but is known as Makeda in Ethiopian tradition and as Bilqis in Arab and Islamic tradition. According to the Jewish historian Josephus, Sheba was the home of Princess Tharbis, a Cushite who is said to have been the wife of Moses before he married Zipporah. Some Quranic exegetes identified Sheba with the People of Tubba.
History
The formative phase of the Sabaeans, or the period prior to the emergence of urban cultures in South Arabia, can be placed the latter part of the 2nd millennium BCE, and was completed by the 10th century BCE, where a fully developed script appears in combination with the technological prowess to construct complex architectural complexes and cities. There is some debate as to the degree to which the movement out of the formative phase was channeled by endogenous processes, or the transfer or technologies from other centers, perhaps via trade and immigration.
Originally, the Sabaeans were part of "communities" (called shaʿbs) on the edge of the Sayhad desert. Very early, at the beginning of the 1st millennium BC, the political leaders of this tribal community managed to create a huge commonwealth of shaʿbs occupying most of South Arabian territory and took on the title "Mukarrib of the Sabaeans".
Emergence
The origin of the Sabaean Kingdom is uncertain and is a point of disagreement among scholars, with estimates placing it around 1200 BCE, by the 10th century BCE at the latest, or a period of flourishing that only begins from the 8th century BCE onwards. Once the polity had been established, Sabaean kings referred to themselves by the title Mukarrib.
First Sabaean kingdom (8th – 1st centuries BCE)
Era of the mukarribs
The first major phase of the Sabaean civilization lasted between the 8th and 1st centuries BCE. For centuries, Saba dominated the political landscape in South Arabia. The 8th century is when the first stone inscriptions appear, and when leaders are already being called by the title Mukarrib ("federator"). Due to this convention, this era can also be called the "Mukarrib period". The title mukarrib was more prestigious than that of mlk ("king") and was used to refer to someone that extended hegemony over other tribes and kingdoms.
Saba reached the height of its powers between the 8th and 6th centuries BCE. In particular, through protracted warfare, Karib'il Watar carried out a series of conquests that extended Sabaean territory to Najran in the north, the Gulf of Aden in the southwest, and eastward from that point along the coast until the western foothills of the Hadhramaut plateau. Saba reigned supreme over South Arabia, and Karib'il established diplomatic contacts with the Assyrian emperor Sennacherib. This territorial range by a South Arabian kingdom would not be seen again until Himyar achieved it over 1,100 years later. Karib'il's success is reflected by the dynastic succession of four rulers from his lineage, including sons, grandson, and great-grandons, a rare occurrence in the face of the rarity of dynastic succession in ancient South Arabian culture. The next time this would be seen was six centuries later in Qataban.
Era of the kings
After the 6th century BCE, Saba was unable to maintain its supremacy over South Arabia in the face of the expanding adjacent powers of Qataban and Hadhramaut militarily, and Ma'in economically, leading it contract back to its core territory around Marib and Sirwah. Sabaean leaders reverted to use of the title malik ("king") instead of mukarrib. This decline began soon after the end of the reign of Karib'il Watar. While Karib'il established hegemony over the Jawf, his immediate successors only consolidated their power over some of its former city-states (including Nashq and Manhayat) whereas others (like Yathill and the towns of Wadhi Raghwan) were absorbed into Ma'in. Qataban expanded into the Southern Highlands, formerly under Sabaean rule.
Economically, the first Sabaean period was dominated by a caravan economy that had market ties with the rest of the Near East. Its first major trading partners were at Khindanu and the Middle Euphrates. Later, this moved to Gaza during the Persian period, and finally, to Petra in Hellenistic times. The South Arabian deserts gave rise to important aromatics which were exported in trade, especially frankincense and myrrh. It also acted as an intermediary for overland trade with neighbours in Africa and further off from India.
By the end of the 1st millennium BCE, several factors came together and brought about the decline of the Sabaean state and civilization. The biggest challenge came from the expansion of the Roman Republic. The Republic conquered Syria in 63 BCE and Egypt in 30 BCE, diverting Saba's overland trade network. The Romans then attempted to conquer Saba around 26/25 BCE with an army sent out under the command of the governor Aelius Gallus, setting Marib to siege. Due to heat exhaustion, the siege had to be quickly given up. However, after conquering Egypt, the overland trade network was redirected to maritime routes, with an intermediary port chosen with Bir Ali (then called Qani). This port was part of the Kingdom of Hadhramaut, far from Sabaean territory. Greatly economically weakened, the Kingdom of Saba was soon annexed by the Himyarite Kingdom, bringing this period to a close.
Second Sabaean kingdom (1st – 3rd centuries CE)
After the disintegration of the first Himyarite Kingdom, the Sabaean Kingdom reappeared and began to vigorously campaign against the Himyarites, and it flourished for another century and a half. This resurgent kingdom was different from the earlier one in many important respects. The most significant change with the earlier Sabaean period is that local power dynamics had shifted from the oasis cities on the desert margin, like Marib, to the highland tribes. The Almaqah temple at Marib returned to being a religious center. Saba inaugurated a new coinage and the remarkable Ghumdan Palace was built at Sanaa which, in this period, had its status elevated to that of a secondary capital next to Marib.
Despite liberating itself from Himyar by around 100 CE, leaders of Himyar continued calling themselves the "king of Saba", as they had been doing during the period in which they ruled the region, to assert their legitimacy over the territory. The Kingdom fell after a long but sporadic civil war between several Yemenite dynasties claiming kingship, and the late Himyarite Kingdom rose as victorious. Sabaean kingdom was finally permanently conquered by the Ḥimyarites around 275 CE. Saba lost its royal status and reverted to a normal tribe, limited to the citizens of Marib, who are named in the last time in South Arabian sources in CIH 541 in requesting assistance from the king in repairing a rupture in the Marib Dam.
Conquests
Conquests of Karib'il Watar
The major conquests in Saba were driven by the exploits of Karib'il Watar. Karib'il conquered all surrounding neighbours, including the Awsan, Qataban, and Hadhramaut. Karib'il's exploits largely unified Yemen.
The conquests of Karib'il are documented in two lengthy inscriptions (RES 3945–3946) discovered at the Temple of Almaqah at Sirwah. These inscriptions describe a series of eight campaigns to show how Karib'il ultimately brought South Arabia under the control of Saba. The first campaign took place in the highlands west of Marib, where Karib'il declares that he had captured 8,000 and killed 3,000 enemies. The second campaign concerned the Kingdom of Awsan, which flourished in the 8th and 7th centuries BCE. Up until the reign of Karib'il, it was a significant regional competitor with the Kingdom of Saba. However, Karib'il's campaign brought about the obliteration of the Kingdom of Awsan. The tribal elite leading Awsan were slaughtered, and the palace of Murattaʿ was destroyed, as well as their temples and inscriptions. The wadi was depopulated, which is reflected in the abandonment of the wadi. Sabaean inscriptions claim that 16,000 were killed and 40,000 prisoners were taken. This may not have been a significant exaggeration, as the Awsan kingdom disappeared as a political entity from the historical record for five or six centuries. The third and fourth campaigns involve attacks against tribes living in low-lying hills that geographically face the Gulf of Aden. The fifth and sixth campaigns were against Nashshan. Nashshan was, like Awsan, one of Saba's most powerful competitors. However, against Karib'il, combined with the destruction of several towns and buildings and the imposition of a tribute on its people. Any dissidents were killed and the cult of Almaqah was imposed onto Nashshan, with Nashshan's leaders being required to build a temple for him. The final two campaigns were against the Tihamah coastal region and the Najran region.
Horn of Africa
The role played by Sabaeans in the formation of Dʿmt (Di'amat), a polity located in the Tigray Region of Ethiopia and founded c. 800 BCE, continues to be debated by scholars. Evidence of strong Sabaean influence includes Sabaic inscriptions and Sabaean temples. Scholars of South Arabian archaeology and epigraphy tend to favour a migration and/or colonisation, while scholars of African archaeology tend to stress an indigenous origin. According to the former view, Sabaean populations migrated to the Horn of Africa to establish and/or maintain the new polity, including through managing trade between the two (ivory might have especially been a driver of the expansion). Notably, five temples for Almaqah, the national god of Saba, were built in what is thought to be the domain of the kingdom, including one at its capital, Yeha, which was possibly modelled after another temple at Sirwah; others temples in the Horn of Africa included the Temple of Meqaber Gaʿewa.
Besides religion, Sabaean culture diffused into Di'amat through the use of objects, architectural techniques, artistic styles, institutions, paleographical styles for writings inscriptions, and the use of abstract symbols. Leaders in Di'amat used the classical South Arabian title, the mukarrib, and one particular title that is seen is the "Mukarrib of Diʿamat and Saba" (mkrb Dʿmt s-S1bʾ). Further, inscriptions mention the complete remainder of the known Sabaean deities. The exact timing of the collapse of Di'amat is not known: it happened around the mid-1st millennium BCE and involved a destruction of Yeha along with a number of adjacent sites. This also happened when Saba was beginning to lose its grip on power over South Arabia.
In 2019 Sabaean inscriptions were found in Somaliland and Puntland, as well as a Sabaean temple whose inscriptions say its construction was ordered by the admiral of Sheba's fleet.
In 2025 Alfredo González-Ruibal said "we can perhaps discern two different models: a proper colonialist one along the northern Somali seaboard, with direct intervention of the state and aimed at the extraction of resources, and a diasporic model in the northern Horn [where Dʿmt was located], led by élites who soon mixed with local people, while maintaining ties with their ancestral homeland".
Military warfare continued between Saba, Ethiopia, and Himyar during the second Sabaean period, with a dynamic and shifting array of alliances. Recently discovered evidence shows that these encounters took place, not only on the peninsula, but also on Ethiopian territory during expeditions launched by the Sabaeans.
