Sudan's advantageous geographic location has made It the recipient to the migrations of many people of different ethnic origins. This led some writers to call it (Mini- Africa).

 

Ethnicity

Sudan's ethnic and linguistic diversity remained one of the most complex in the world in 1991. Its nearly 600 ethnic groups spoke more than 400 languages and dialects, many of them intelligible to only a small number of individuals. In the 1980s and 1990s some of these small groups became absorbed by larger groups, while migration often caused individuals reared in one tongue to converse only in the dominant language of the new area. Such was the case with migrants to the Three Towns. There Arabic was the lingua franca despite the use of English by many of the elite. Some linguistic groups had been absorbed by accommodation, others by conflict. Most Sudanese were, of necessity, multilingual. Choice of language played a political role in the ethnic and religious cleavage between the northern and southern Sudanese. English was associated with being non-Muslim, as Arabic was associated with Islam. Thus language

 

Language

Language differences have served as a partial basis for ethnic classification and as symbols of ethnic identity. Such differences have been obstacles to the flow of communication in a state as linguistically fragmented as Sudan. These barriers have been overcome in part by the emergence of some languages as lingua francas and by a considerable degree of multilingualism in some areas.

Most languages spoken in Africa fall into four language superstocks. Three of them--Afro-Asiatic, Niger-Kurdufanian, and Nilo-Saharan--are represented in Sudan. Each is divided into groups that are in turn subdivided into sets of closely related languages. Two or more major groups of each superstock are represented in Sudan, which has been historically both a northsouth and an east-west migration crossroad.

 

The most widely spoken language in the Sudan is Arabic, a member of the Semitic branch of the Afro-Asiatic language family. Cushitic, another major division of the Afro-Asiatic language, is represented by Bedawiye (with several dialects), spoken by the largely nomadic Beja. Chadic, a third division, is represented by its most important single language, Hausa, a West African tongue used by the Hausa themselves and employed by many other West Africans in Sudan as a lingua franca.

 

Niger-Kurdufanian is first divided into Niger-Congo and Kordofanian. The widespread Niger-Congo language group includes many divisions and subdivisions of languages. Represented in Sudan are Azande and several other tongues of the Adamawa-Eastern language division, and Fulani of the West Atlantic division. The Kurdufanian stock comprises only thirty to forty languages spoken in a limited area of Sudan, the Nuba Mountains and their environs.

 

The designation of a Nilo-Saharan superstock has not been fully accepted by linguists, and its constituent groups and subgroups are not firmly fixed, in part because many of the languages have not been well studied. Assuming the validity of the category and its internal divisions, however, eight of its nine major divisions and many of their subdivisions are well represented in Sudan, where roughly seventy-five languages, well over half of those named in the 1955-56 census, could be identified as Nilo-Saharan. Many of these languages are used only by small groups of people. Only six or seven of them were spoken by 1 percent or more of Sudan's 1956 population. Perhaps another dozen were the home languages of 0.5 to 1 percent. Many other languages were used by a few thousand or even a few hundred people.

 

The number of languages and dialects in Sudan is assumed to be about 400, including languages spoken by an insignificant number of people. Moreover, languages of smaller ethnic groups tended to disappear when the groups assimilated with more dominant ethnic units.

 

Several lingua francas have emerged and many peoples have become genuinely multilingual, fluent in a native language spoken at home, a lingua franca, and perhaps other languages. Arabic is the primary lingua franca in Sudan, given its status as the country's official language and as the language of Islam. Arabic, however, has several different forms, and not all who master one are able to use another. Among the varieties noted by scholars are classical Arabic, the language of the Quran (although generally not a spoken language and only used for printed work and by the educated in conversation); Modern Standard Arabic, derived from classical Arabic; and at least two kinds of colloquial Arabic in the Sudan--that spoken in roughly the eastern half of the country and called Sudanese colloquial Arabic and that spoken in western Sudan, closely akin to the colloquial Arabic spoken in Chad. There are other colloquial forms. A pidgin called Juba Arabic is peculiar to southern Sudan. Although some Muslims might become acquainted with classical Arabic in the course of rudimentary religious schooling, very few except the most educated know it except by rote.

 

Modern Standard Arabic is in principle the same everywhere in the Arab world and presumably permits communication among educated persons whose mother tongue is one or another form of colloquial Arabic. Despite its international character, however, Modern Standard Arabic varies from country to country. It has been, however, the language used in Sudan's central government, the press, and Radio Omdurman. The latter also broadcast in classical Arabic. One observer, writing in the early 1970s, noted that Arabic speakers (and others who had acquired the language informally) in western Sudan found it easier to understand the Chadian colloquial Arabic used by Chad Radio than the Modern Standard Arabic used by Radio Omdurman. This might also be the case elsewhere in rural Sudan where villagers and nomads speak a local dialect of Arabic.

 

Despite Arabic's status as the official national language, English was acknowledged as the principal language in southern Sudan in the late 1980s. It was also the chief language at the University of Khartoum and was the language of secondary schools even in the north before 1969. The new policy for higher education announced by the Sudanese government in 1990 indicated the language of instruction in all institutions of higher learning would be Arabic.

 

Nevertheless, in the south, the first two years of primary school were taught in the local language. Thereafter, through secondary school, either Arabic or English could become the medium of instruction (English and Arabic were regarded as of equal importance); the language not used as a medium was taught as a subject. In the early 1970s, when this option was established, roughly half the general secondary classes (equivalent to grades seven through nine) were conducted in Arabic and half in English in Bahr al Ghazal and Al Istiwai provinces. In early 1991, with about 90 percent of the southern third of the country controlled by the Sudanese People's Liberation Army (SPLA), the use of Arabic as a medium of instruction in southern schools remained a political issue, with many southerners regarding Arabic as an element in northern cultural domination.

 

Juba (or pidgin) Arabic, developed and learned informally, had been used in southern towns, particularly in Al Istiwai, for some time and had spread slowly but steadily throughout the south, but not always at the expense of English. The Juba Arabic used in the marketplace and even by political figures addressing ethnically mixed urban audiences could not be understood by northern Sudanese.

 

Ethnic Groups

The definition and boundaries of ethnic groups depend on how people perceive themselves and others. Language, cultural characteristics, and common ancestry may be used as markers of ethnic identity or difference, but they do not always define groups of people. Thus, the people called Atuot and the much larger group called Nuer spoke essentially the same language, shared many cultural characteristics, and acknowledged a common ancestry, but each group defined itself and the other as different. Identifying ethnic groups in Sudan was made more complicated by the multifaceted character of internal divisions among Arabic-speaking Muslims, the largest population that might be considered a single ethnic group.

 

The distinction between Sudan's Muslim and non-Muslim people has been of considerable importance in the country's history and provides a preliminary ordering of the ethnic groups. It does not, however, correspond in any simple way to distinctions based on linguistic, cultural, or racial criteria nor to social or political solidarity. Ethnic group names commonly used in Sudan and by foreign analysts are not always used by the people themselves. That is particularly true for non-Arabs known by names coined by Arabs or by the British, who based the names on terms used by Arabs or others not of the group itself. Thus, the Dinka and the Nuer, the largest groups in southern Sudan, call themselves, respectively, Jieng and Naath.

 

The two largest of the supratribal categories in the early 1990s were the Juhayna and the Jaali (or Jaalayin). The Juhayna category consisted of tribes considered nomadic, although many had become fully settled. The Jaali encompassed the riverine, sedentary peoples from Dunqulah to just north of Khartoum and members of this group who had moved elsewhere. Some of its groups had become sedentary only in the twentieth century. Sudanese saw the Jaali as primarily indigenous peoples who were gradually arabized. Sudanese thought the Juhayna were less mixed, although some Juhayna groups had become more diverse by absorbing indigenous peoples. The Baqqara, for example, who moved south and west and encountered the Negroid peoples of those areas were scarcely to be distinguished from them.

 

A third supratribal division of some importance was the Kawahla, consisting of thirteen tribes of varying size. Of these, eight tribes and segments of the other five were found north and west of Khartoum. There people were more heavily dependent on pastoralism than were the segments of the other five tribes, who lived on either side of the White Nile from south of Khartoum to north of Kusti. This cluster of five groups (for practical purposes independent tribes) exhibited a considerable degree of self-awareness and cohesion in some circumstances, although that had not precluded intertribal competition for local power and status.

 

The ashraf (sing., sharif), who claim descent from the Prophet Muhammad, were found in small groups (lineages) scattered among other Arabs. Most of these lineages had been founded by religious teachers or their descendants. A very small group of descendants of the Funj Dynasty also claimed descent from the Ummayyads, an early dynasty of caliphs based in present- day Syria. That claim had little foundation, but it served to separate from other Arabs a small group living on or between the White Nile and the Blue Nile. The term ashraf was also applied in Sudan to the family of Muhammad Ahmad ibn as Sayyid Abd Allah, known as the Mahdi (1848-85; see The Mahdiyah , ch. 1).

The division into Jaali and Juhayna did not appear to have significant effect on the ways in which individuals and groups regarded each other. Conflicts between tribes generally arose from competition for good grazing land, or from the competing demands of nomadic and sedentary tribes on the environment. Among nomadic and recently sedentary Arabs, tribes and subtribes competed for local power (see The Social Order , this ch.).

Membership in tribal and subtribal units is generally by birth, but individuals and groups may also join these units by adoption, clientship, or a decision to live and behave in a certain way. For example, when a sedentary Fur becomes a cattle nomad, he is perceived as a Baqqara. Eventually the descendants of such newcomers are regarded as belonging to the group by birth.

Tribal and subtribal units divide the Arab ethnic category vertically, but other distinctions cut across Arab society and its tribal and subtribal components horizontally by differences of social status and power. Still another division is that of religious associations (see Islamic Movements and Religious Orders , this ch.).

Nubians

In the early 1990s, the Nubians were the second most significant Muslim group in Sudan, their homeland being the Nile River valley in far northern Sudan and southern Egypt. Other, much smaller groups speaking a related language and claiming a link with the Nile Nubians have been given local names, such as the Birqid and the Meidab in Darfur State . Almost all Nile Nubians speak Arabic as a second language; some near Dunqulah have been largely arabized and are referred to as Dunqulah.

In the mid-1960s, in anticipation of the flooding of their lands after the construction of the Aswan High Dam, 35,000 to 50,000 Nile Nubians resettled at Khashm al Qirbah on the Atbarah River in what was then Kassala Province. It is not clear how many Nubians remained in the Nile Valley. Even before the resettlement, many had left the valley for varying lengths of time to work in the towns, although most sought to maintain a link with their traditional homeland. In the 1955-56 census, more Nile Nubians were counted in Al Khartum Province than in the Nubian country to the north. A similar pattern of work in the towns was apparently followed by those resettled at Khashm al Qirbah. Many Nubians there retained their tenancies, having kin oversee the land and hiring non-Nubians to work it. The Nubians, often with their families, worked in Khartoum, the town of Kassala, and Port Sudan in jobs ranging from domestic service and semi-skilled labor to teaching and civil service, which required literacy. Despite their knowledge of Arabic and their devotion to Islam, Nubians retained a considerable self-consciousness and tended to maintain tightly knit communities of their own in the towns.

Beja

The Beja probably have lived in the Red Sea Hills since ancient times. Arab influence was not significant until a millennium or so ago, but it has since led the Beja to adopt Islam and genealogies that link them to Arab ancestors, to arabize their names, and to include many Arabic terms in their language. Although some Arabs figure in the ancestry of the Beja, the group is mostly descended from an indigenous population, and they have not become generally arabized. Their language (Bedawiye) links them to Cushitic-speaking peoples farther south.

 

In the 1990s, most Beja belonged to one of four groups--the Bisharin, the Amarar, the Hadendowa, and the Bani Amir. The largest group was the Hadendowa, but the Bisharin had the most territory, with settled tribes living on the Atbarah River in the far south of the Beja range and nomads living in the north. A good number of the Hadendowa were also settled and engaged in agriculture, particularly in the coastal region near Tawkar, but many remained nomads. The Amarar, living in the central part of the Beja range, seemed to be largely nomads, as were the second largest group, the Bani Amir, who lived along the border with northern Ethiopia. The precise proportion of nomads in the Beja population in the early 1990s was not known, but it was far greater relatively than the nomadic component of the Arab population. The Beja were characterized as conservative, proud, and aloof even toward other Beja and very reticent in relations with strangers. They were long reluctant to accept the authority of central governments.

 

Fur

The Fur, ruled until 1916 by an independent sultanate and oriented politically and culturally to peoples in Chad, were a sedentary, cultivating group long settled on and around the Jabal Marrah. Although the ruling dynasty and the peoples of the area had long been Muslims, they have not been arabized. Livestock has played a small part in the subsistence of most Fur. Those who acquired a substantial herd of cattle could maintain it only by living like the neighboring Baqqara Arabs, and those who persisted in this pattern eventually came to be thought of as Baqqara.

aghawa

Living on the plateau north of the Fur were the seminomadic people calling themselves Beri and known to the Arabs as Zaghawa. Large numbers of the group lived in Chad. Herders of cattle, camels, sheep, and goats, the Zaghawa also gained a substantial part of their livelihood by gathering wild grains and other products. Cultivation had become increasingly important but remained risky, and the people reverted to gathering in times of drought. Converted to Islam, the Zaghawa nevertheless retain much of their traditional religious orientation.

Masalit, Daju, and Berti

Of other peoples living in Darfur in the 1990s who spoke Nilo-Saharan languages and were at least nominally Muslim, the most important were the Masalit, Daju, and Berti. All were primarily cultivators living in permanent villages, but they practiced animal husbandry in varying degrees. The Masalit, living on the Sudan-Chad border, were the largest group. Historically under a minor sultanate, they were positioned between the two dominant sultanates of the area, Darfur and Wadai (in Chad). A part of the territory they occupied had been formerly controlled by the Fur, but the Masalit gradually encroached on it in the first half of the twentieth century in a series of local skirmishes carried out by villages on both sides, rather than the sultanates. In 1990-91 much of Darfur was in a state of anarchy, with many villages being attacked. There were many instances in which Masalit militias attacked Fur and other villages (see Western Sudan , ch. 4).

 

The Berti consisted of two groups. One lived northeast of Al Fashir; the other had migrated to eastern Darfur and western Kurdufan provinces in the nineteenth century. The two Berti groups did not seem to share a sense of common identity and interest. Members of the western group, in addition to cultivating subsistence crops and practicing animal husbandry, gathered gum arabic for sale in local markets. The Berti tongue had largely given way to Arabic as a home language.

The term Daju was a linguistic designation that was applied to a number of groups scattered from western Kurdufan and southwestern Darfur states to eastern Chad. These groups called themselves by different names and exhibited no sense of common identity.

West Africans

Living in Sudan in 1990 were nearly a million people of West African origin. Together, West Africans who have become Sudanese nationals and resident nonnationals from West Africa made up 6.5 percent of the Sudanese population. In the mid-1970s, West Africans had been estimated at more than 10 percent of the population of the northern provinces. Some were descendants of persons who had arrived five generations or more earlier; others were recent immigrants. Some had come in self-imposed exile, unable to accommodate to the colonial power in their homeland. Others had been pilgrims to Mecca, settling either en route or on their return. Many came over decades in the course of the great dispersion of the nomadic Fulani; others arrived, particularly after World War II, as rural and urban laborers or to take up land as peasant cultivators.

 

Nearly 60 percent of people included in the West African category were said to be of Nigerian origin (locally called Borno after the Nigerian emirate that was their homeland). Given Hausa dominance in northern Nigeria and the widespread use of their language there and elsewhere, some non-Hausa might also be called Hausa and describe themselves as such. But the Hausa themselves, particularly those long in Sudan, preferred to be called Takari. The Fulani, even more widely dispersed throughout West Africa, may have originated in states other than Nigeria. Typically, the term applied to the Fulani in Sudan was Fallata, but Sudanese also used that term for other West Africans.

 

The Fulani nomads were found in many parts of central Sudan from Darfur to the Blue Nile, and they occasionally competed with indigenous populations for pasturage. In Darfur groups of Fulani origin adapted in various ways to the presence of the Baqqara tribes. Some retained all aspects of their culture and language. A few had become much like Baqqara in language and in other respects, although they tended to retain their own breeds of cattle and ways of handling them. Some of the Fulani groups in the eastern states were sedentary, descendants of sedentary Fulani of the ruling group in northern Nigeria.

 

Nilotes

Nilote is a common name for many of the peoples living on or near the Bahr al Jabal and its tributaries. The term refers to people speaking languages of one section of the Nilotic subbranch of the Eastern Sudanic branch of Nilo-Saharan and sharing a myth of common origin. They are marked by physical similarity and many common cultural features. Many had a long tradition of cattlekeeping, including some for whom cattle were no longer of practical importance. Because of their adaptation to different climates and their encounters, peaceful and otherwise, with other peoples, there was also some diversity among the Nilotes.

 

Despite the civil war and famine, the Nilotes still constituted more than three-fifths of the population of southern Sudan in 1990. One group--the Dinka--made up roughly two-thirds of the total category, 40 percent or more of the population of the area and more than 10 percent of Sudan's population. The Dinka were widely distributed over the northern portion of the southern region, particularly in Aali an Nil and Bahr al Ghazal. The next largest group, only one-fourth to one-third the size of the Dinka, were the Nuer. The Shilluk, the third largest group, had only about one-fourth as many people as the Nuer, and the remaining Nilotic groups were much smaller.

 

The larger and more dispersed the group, however, the more internally varied it had become. The Dinka and Nuer, for example, did not develop a centralized government encompassing all or any large part of their groups. The Dinka are considered to have as many as twenty-five tribal groups. The Nuer have nine or ten separately named groups.

 

Armed conflict between and within ethnic groups continued well into the twentieth century. Sections of the Dinka fought sections of the Nuer and each other. Other southern groups also expanded and contracted in the search for cattle and pasturage. The Nuer absorbed some of the Dinka, and some present-day sections of the Nuer have significant Dinka components.

 

Relations among various southern groups were affected in the nineteenth century by the intrusion of Ottomans, Arabs, and eventually the British. Some ethnic groups made their accommodation with the intruders and others did not, in effect pitting one southern ethnic group against another in the context of foreign rule. For example, some sections of the Dinka were more accommodating to British rule than were the Nuer. These Dinka treated the resisting Nuer as hostile, and hostility developed between the two groups as result of their differing relationships to the British. The granting of Sudanese independence in 1956, and the adoption of certain aspects of Islamic law or the sharia, by the central government in 1983 greatly influenced the nature of relations among these groups in modern times.

 

The next largest group of Nilotes, the Shilluk (self-named Collo), were not dispersed like the Dinka and the Nuer, but settled mainly in a limited, uninterrupted area along the west bank of the Bahr al Jabal, just north of the point where it becomes the White Nile proper. A few lived on the eastern bank. With easy access to fairly good land along the Nile, they relied much more heavily on cultivation and fishing than the Dinka and the Nuer did, and had fewer cattle. The Shilluk had truly permanent settlements and did not move regularly between cultivating and cattle camps.

 

Unlike the larger groups, the Shilluk, in the Upper Nile, were traditionally ruled by a single politico-religious head (reth), believed to become at the time of his investiture as king the representative, if not the reincarnation, of the mythical hero Nyiking, putative founder of the Shilluk. The administrative and political powers of the reth have been the subject of some debate, but his ritual status was clear enough: his health was believed to be closely related to the material and spiritual welfare of the Shilluk. It is likely that the territorial unity of the Shilluk and the permanence of their settlements contributed to the centralization of their political and ritual structures. In the late 1980s, the activities against the SPLA by the armed militias supported by the government seriously alienated the Shilluk in Malakal.

Bari, Kuku, Kakwa, and Mandari

Several peoples living mainly to the south and east of the Nilotes spoke languages of another section of the Nilotic subbranch of Eastern Sudanic. Primary among them were the Bari and the closely related Kuku, Kakwa, and Mandari. The Bari and Mandari who lived near the Nilotes had been influenced by them and had sometimes been in conflict with them in the past. The more southerly Kuku and Kakwa lived in the highlands, where cultivation was more rewarding than cattle-keeping or where cattle diseases precluded herding.

 

Murle, Didinga, and Others

Two other tribes, the Murle and the Didinga, spoke Eastern Sudanic languages of subbranches other than Nilotic. The Murle had dwelt in southern Ethiopia in the nineteenth century and some were still there in the 1990s. Others had moved west and had driven out the local Nilotes, whom they reportedly regarded with contempt, and acquired a reputation as warriors. Under environmental pressure, the Murle raided other groups in the late 1970s and early 1980s.

 

Along the mountainous border with Ethiopia in Al Awsat State lived several small heterogeneous groups. Some, like the Uduk, spoke languages of the Koman division of Nilo-Saharan and were believed to have been in the area since antiquity. Others, like the Ingessana, were refugees driven into the hills by the expansion of other groups. Most of these peoples straddling the Sudan-Ethiopia border had experienced strife with later-arriving neighbors and slave-raiding by the Arabs. All adapted by learning the languages of more dominant groups.

 

Azande

In western Al Istiwai and Bahr al Ghazal states lived a number of small, sometimes fragmented groups. The largest of these groups were the Azande, who comprised 7 to 8 percent of the population of southern Sudan and were the dominant group in western Al Istiwai.

 

The Azande had emerged in the eighteenth and nineteenth centuries when groups of hunters, divided into aristocrats and commoners, entered the northeastern past of present-day Zaire (and later southwestern Sudan) and conquered the peoples already there. Although the aristocrats provided ruling kings and nobles, they did not establish an inclusive, centralized state. The means of succession to kingship, however, encouraged Azande expansion. A man succeeded to his father's throne only when he had vanquished those of his brothers who chose to compete for it. The brothers--princes without land or people but with followers looking for the fruits of conquest--would find and rule hitherto unconquered groups. Thus, the Azande became a heterogeneous people.

 

Their earlier military and political successes notwithstanding, the Azande in the twentieth century were poor, largely dependent on cultivation (hunting was no longer a feasible source of food), and afflicted by sleeping sickness. The British colonial authorities instituted a project, known as the Azande Scheme, involving cotton growing and resettlement in an effort to deal with these problems. The program failed, however, for a variety of reasons, including an inadequate understanding of Azande society, economy, and values on the part of the colonial planners. Azande society deteriorated still further, a deterioration reflected in a declining birthrate. Azande support of the Anya Nya guerrilla groups, as well as conflicts with the Dinka, also served to worsen the Azande's situation. In the early 1980s, there was talk of resurrecting a revised Azande project but the resumption of the civil war in 1983 prevented progress.

 

Bviri and Ndogo

Several other groups of cultivators in southwestern Sudan spoke languages closely akin to that of the Azande but lacked a dominant group. The most important seemed to be the Bviri. They and a smaller group called Ndogo spoke a language named after the latter; other, smaller communities spoke dialects of that tongue. These communities did not share a sense of common ethnic identity, however.

 

Others

The other groups in southwestern Sudan spoke languages of the central branch of Nilo-Saharan and were scattered from the western Bahr al Ghazal (the Kreish) to central Al Istiwai (the Moru and the Avukaya) to eastern Al Istiwai (the Madi). In between, in Al Istiwai, were such peoples as the Bongo and the Baka. The languages of Moru and Madi were so close, as were aspects of their cultures, that they were sometimes lumped together. The same was true of the Bongo and the Baka, but there was no indication that either pair constituted a self-conscious ethnic group.

 

Nuba

Living in the Nuba Mountains of southern Kurdufan State were perhaps three dozen small groups collectively called the Nuba but varying considerably in their culture and social organization. For example, some were patrilineally organized, others adhered to matrilineal patterns, and a very few--the southeastern Nuba--had both patrilineal and matrilineal groupings in the same community. The Kurdufanian languages these people spoke were not generally mutually intelligible except for those of some adjacent communities.

 

Despite the arabization of the people around them, only small numbers of Nuba had adopted Arabic as a home language, and even fewer had been converted to Islam. Some had, however, served in the armed forces and police. Most remained cultivators; animal husbandry played only a small part in their economy.
