Sabaean and Minaean kingdoms
The Greek writer Eratosthenes (3rd century bce) described “Eudaimon Arabia” (i.e., Arabia Felix, or Yemen) as inhabited by four major peoples (ethne), and it is on the basis of his nomenclature for these groups that modern scholars are accustomed to speak of Minaeans, Sabaeans, Qatabānians, and Hadramites. The fourfold categorization does indeed correspond to the linguistic data, but the political and historical facts are a good deal more complex. The capitals of the four peoples were not located in the centres of their respective territories but instead lay close together on the western, southern, and eastern fringes of a tract of sand desert known to medieval Arab geographers as the Ṣayhad (modern Ramlat al-Sabʿatayn). This off-centre placing has been thought to originate from proximity to the trade route by which frankincense was conveyed from Hadhramaut first westward, then north to Najrān, then up the west coast of Arabia to Gaza, and across the peninsula to the east coast. The territories attached to the latter three of the capitals spread out fanwise into the mountainous regions.
Sabaeans
The people who called themselves Sabaʾ (biblical Sheba) are both the earliest and the most abundantly attested in the surviving written records. Their centre was at Maʾrib, east of present-day Sanaa and on the edge of the sand desert. (In the indigenous inscriptions Maʾrib is rendered Mryb or Mrb; the modern spelling is based on an unjustified “correction” by medieval Arabic writers.) The town lay in a formerly highly cultivated area watered by the great Maʾrib Dam, which controlled the flow from the extensive Wadi Dhana basin.
Sabaean rulers—who are mentioned in Assyrian annals of the late 8th and early 7th centuries bce (although some scholars date Sabaean inscriptions to about the 6th century bce)—were responsible for impressive constructions both cultic and irrigational, including the greatest part of what is now visible of the dam; but there are traces of earlier dam works, and the silt deposits indicate agricultural exploitation far back in prehistory.
From the early historic period one ruler, named Karibʾil Watar, has left a long epigraphic record of victories over peoples throughout the major part of Yemen, most importantly the Awsānian kingdom to the southeast, but the victories did not lead to permanent conquest. Nor did his campaigns ever extend into the Hadhramaut region or to the Red Sea coastal area. At no period of their history as an independent people did the Sabaeans have real control of those two areas; in the Red Sea coastal area the sole indication of their presence is a small temple near Zabīd, probably attached to a military outpost guarding a route down to the sea.
Two secondary centres were Ṣirwāh, on a tributary of the Wadi Dhana above the dam, and Nashq (now Al-Bayḍāʾ), at the western end of Wadi al-Jawf.
From perhaps just before the Christian era, however, the highland regions, both north and west of Sanaa, played a much more active part in Sabaean affairs, and some of the rulers belonged to highland clans. The early centuries of the Christian era also saw the emergence of Sanaa as a government centre and royal residence (in its palace, Ghumdān) almost rivaling the status of Maʾrib. Nevertheless, Maʾrib (with its palace, Salḥīn) retained its prestige into the 6th century ce.
Sabaean rulers of the early period employed a regnal style consisting of two names, each chosen from a very short list of alternatives; possible permutations were thus limited, and the same style recurs several times over. In drafting their own texts, the rulers adopted the title mukarrib, now generally thought to mean “unifier” (with allusion to the process of expansion of Sabaean influence over neighbouring communities). Persons other than the rulers never used this title in their texts but referred to the rulers by their regnal styles or occasionally as “king of Maʾrib.” Later the title mukarrib disappeared, and the rulers referred to themselves, and were referred to by their subjects, as “king of Sabaʾ.”
As among the Minaeans, the early rulers were only one element in a legislature including both a council and representatives of the nation. The rulers’ personal activity lay mainly in building and in leading wars. The first three centuries of the Christian era have yielded a more ample documentation than any other period, but during those centuries the Sabaeans were facing a strong threat from the Ḥimyarites to the south of them. The Ḥimyarites succeeded at times in gaining supremacy over the Sabaeans, and at the end of the 3rd century they definitively absorbed the Sabaeans into their realm. In the wars of the 1st century onward, the kings (whether Sabaean or Ḥimyarite) were supported both by a national army (khamīs) under their own command and by contingents raised from the associated communities led by qayls, belonging to the aristocratic clans that headed each associated community. The oldest documents attest a number of other kingdoms. The most important was Awsān, which lay in the highlands to the south of the Wadi Bayḥān. An early Sabaean text speaks of a massive defeat of Awsān, in terms that attest its high significance. Yet the kingdom had a brief resurgence much later, around the turn of the Christian era, when it appears to have been wealthy and heavily influenced by Hellenistic culture. One of its kings of this period was the only Yemeni ruler to be (like the Ptolemies and Seleucids) accorded divine honours, and his portrait statuette is dressed in Greek garb, contrasting with those of his predecessors who are dressed in Arabian style, with kilt and shawl. Awsānian inscriptions are in the Qatabānian language (which might account for the fact that Eratosthenes gives no separate mention to Awsān in his list of the main ethne).
Minaeans
The Minaean kingdom (Maʿīn) lasted from the 4th to the 2nd century bce and was predominantly a trading organization that, for the period, monopolized the trade routes. References to Maʿīn occur earlier in Sabaean texts, where they seem to be loosely associated with the ʿĀmir people to the north of the Minaean capital of Qarnaw (now Maʿīn), which is at the eastern end of the Wadi Al-Jawf and on the western border of the Ṣayhad sands. The Minaeans had a second town surrounded by impressive and still extant walls at Yathill, a short distance south of Qarnaw, and they had trading establishments at Dedān and in the Qatabānian and Hadramite capitals. The overwhelming majority of Minaean inscriptions come from Qarnaw, Yathill, and Dedān, and there is virtually no evidence of territorial possessions apart from the immediate vicinities of these three centres, which have more the aspect of typical “caravan cities.” A thin scattering of Minaean inscriptions has been found in places just outside Arabia, such as Egypt and the island of Delos, all manifestly resulting from far-flung trading activities; and texts from Qarnaw refer to a number of important points on the caravan routes, such as Yathrib (Medina) and Gaza, and also to interruption of trade by one of the several phases of warfare between Egypt and the Seleucids of Syria. An explicit mention of caravans is perhaps found in the expression mʿn mṣrn, interpreted by the scholar Mahmud Ali Ghul as “the Minaean caravaneers.”
Minaean social structure differed from that of the other three, predominantly agricultural peoples. The latter were federations of communities (often termed by modern scholars “tribes,” though they were not genealogically based) grouped under a leading community, with the nation as a whole designated by the name of the hegemonial community, followed by the phrase “and the [associated] communities.” The Minaeans, however, were subdivided into groups of varying size and importance, some quite small, with none exercising a dominating role over the others. Among the other three peoples the office of “elder” (kabīr) was normally filled by the head of one of the associated communities in a national federation. Among the Minaeans, however, the kabīr was a biennially appointed magistrate controlling one of the trading settlements or, in some cases, invested with authority in all of them. Legislative functions were exercised by the king acting together with a council and representatives of all the Minaean social classes. Minaean inscriptions make no mention of wars undertaken by the king or the state; this suggests that Maʿīn may have enjoyed covenants of safe-conduct with their neighbours along the trade routes.
Other pre-Islamic Yemeni kingdoms
Qatabānians
The heartland of the Qatabān people was Wadi Bayḥān, with the capital, Timnaʿ, at its northern end, and Wadi Ḥarīb, immediately west of Bayḥān. As in the case of Maʿīn, the earliest references are in Sabaean inscriptions; native Qatabānian inscriptions do not seem to antedate the 4th century bce. Timnaʿ was destroyed by fire at a date not easy to fix; pottery evidence has been thought to suggest the 1st century ce, but epigraphy points to a survival of the kingdom at least until the end of the 2nd century. Its fortunes had fluctuated: in the earliest Sabaean phase it was “liberated” by the Sabaeans from Awsānian domination in the above-mentioned defeat of Awsān. At some periods the Qatabānians themselves dominated a federacy similar to the Sabaean one, and at a relatively late date a ruler whom his subjects called “King of Qatabān” styled himself mukarrib of Qatabān. Inasmuch as Eratosthenes says that this people extended to “both seas”—i.e., the Red Sea and the Gulf of Aden—it might be inferred that there was some sort of Qatabānian presence in the southwest corner of the peninsula, an area later ruled by the Ḥimyarites.
Hadramites
Inscriptions from the Hadramite kingdom are scantier in number than from the Sabaean, Minaean, or Qatabānian. Yet the Hadramite was probably the wealthiest of them all. Hadhramaut and the Saʾkal area to the east (modern Dhofar province of the sultanate of Oman) are the only places in Arabia where climatic conditions make production of frankincense possible, and Pliny wrote that the whole of the produce was collected at the Hadramite capital, Shabwah, on the eastern fringe of the Ṣayhad sands, and taxed there before being handed over to the caravans that carried it to the Mediterranean and Mesopotamia. In addition, Hadhramaut was an entrepôt for Indian goods brought by sea and then forwarded by land. The caravan trade may have suffered to some degree from competition by Red Sea shipping, which, from the 1st century ce, began to sail through the Bab El-Mandeb Strait into the Indian Ocean. Nevertheless, as late as about 230 ce a king of Hadhramaut received missions from India and Palmyra (Tadmor), at the opposite ends of the long-standing trade route along which Hadhramaut occupied a central position. At Shabwah, French archaeological work begun in 1975 adjacent to the visible temple ruin has revealed a walled town of larger extent than any other ancient Yemeni site. The palace, on the opposite side of the town from the temple, was, according to the archaeological evidence, a truly magnificent building. The main port of Hadhramaut was at Cane on the bay of Biʾr ʿAlī; and the Hadramites had a settlement at Samhar-m (now Khawr Rawrī) on Qamar Bay in the Saʾkal region, founded about the turn of the Christian era.
