Ethnic groups and languages
Almost all Libyans speak Arabic, the country’s official language. They claim descent from the Bedouin Arab tribes of the Banū Hilāl and the Banū Sulaym, who are said to have invaded the Maghrib in the 11th century. The government’s embrace of Arab nationalism has reduced Western influences, although English is still widely used as a second language in international business and politics. At the beginning of the 21st century, Libya’s population included a substantial number of foreign migrant workers—largely from sub-Saharan African countries—temporarily residing in the country. The tribe (qabīlah), a form of social organization that allowed the grouping of nomadic peoples scattered across the country’s vast spaces, was the foundation of social order for much of Libya’s history.
The Imazighen (Berbers) are believed to have been the earliest inhabitants of Libya. The main Amazigh (plural Imazighen) groups were the Luata, the Nefusa, and the Adassa. They lived in coastal oases and practiced sedentary agriculture. Most Imazighen have been assimilated into Arab society except in the Nafūsah Plateau region, Awjilah, Hūn, Socra, and Zuwarah. The Imazighen of Libya speak languages that are classified as Afro-Asiatic but have adopted the Arabic alphabet. Many are bilingual in Nafusi (an Amazigh language) and Arabic; most are Sunni Muslims. There is also a community of some 30,000 people once called Gypsies but known in North Africa as Dom (see also Roma), who speak Domari (an Indo-European language).
Arab migrations to the region began with the rise of Islam in the 7th century. The initial Arab incursions were essentially military and had little effect upon the composition of the population. Oral tradition suggests that invasions of the Banū Hilāl in 1049 and the Banū Sulaym later in the 11th century took major migrations of nomadic tribes from eastern Arabia to Libya. However, scholarship later suggested that these movements too were not invasions but rather slow migrations of Arab peoples that occurred over several centuries.
The Banū Sulaym were composed of four main groups—the Banū Hebib, the ʿAwf, the Debbab, and the Zegb. The Hebib settled in Cyrenaica, while the others went to Tripolitania. The arrival of these and other Arab groups led to political upheaval and the steady Arabization of Libya’s Amazigh populations. The result was that by the 20th century the great majority of Libya’s inhabitants were Arabic-speaking Muslims of mixed descent.
Several other social groups exist alongside the tribes. Among these are the sharifs (holy tribes), who came originally from the Fezzan. The sharifs claim direct descent from the Prophet Muhammad; their alleged blood relationship with the Prophet gives them a powerful standing in Muslim society. Extensive tracts of land in the oases of western Libya are under sharifian control.
The marabouts (Muslim religious leaders credited with supernatural powers) arrived in Libya from Saguia el-Hamra, in what is now Western Sahara. The maraboutic tribes are descended from holy men who also claimed a privileged relationship with Muhammad. They believed in an ascetic life, manifested by their hermit lifestyle. In areas where their teachings and way of life made them acceptable to the local inhabitants, they settled and founded tribes pledged to the pure way of life.
The Koulouglis are descended from the Janissaries (elite Turkish soldiers who ruled Libya following the Ottoman conquest) and the Amazigh and Christian slave women with whom they intermarried. They have served since Ottoman times as a scribal class and are concentrated in and around villages and towns. They speak Arabic and practice Islam.
The trans-Saharan slave trade, which continued through the early 20th century, took black Africans and their cultures to Libya, particularly to the Fezzan and Tripolitania. Though they previously spoke Nilo-Saharan and Niger-Congo languages of the central Sahara and eastern Sudan, today they speak Arabic and have adopted Islam.
Small groups of Tuareg nomads live in the southwest, especially around the oases of Ghadames and Ghāt. They are gradually assuming a sedentary lifestyle. In the southeast, isolated nomadic Teda (Tubu) communities are slowly gravitating toward the north and the Al-Kufrah oasis in search of employment.
Religion
Most Libyans are Muslim, and the vast majority are Sunnis. There are also very small minorities of Roman Catholic and Orthodox Christians. In Cyrenaica the influence of the Sanūsiyyah, a 19th-century militant Islamic brotherhood, remains strong. Although a Jewish minority was long established in Tripolitania, most Jews left the country in the late 1960s, many of them immigrating to Italy.
Settlement patterns
The majority of the population lives in Tripolitania, mainly in Tripoli and other cities along the coast and on the Nafūsah Plateau. A smaller proportion of the people live in Cyrenaica, primarily in Benghazi and other coastal cities. The remainder of the population is found in the oasis towns of the Fezzan.
The vast majority of the rural population lives in oases on the coast and is engaged in irrigation farming; plots of land are usually small and held in individual ownership. On the Nafūsah Plateau, however, where water is less readily available, a sophisticated agrarian system based on olive- and fruit-tree cultivation and associated livestock raising has evolved. In Cyrenaica the premodern economy was based on nomadic and seminomadic pastoralism. Arable farming has largely been an adjunct of the pastoral system, with shifting dry-land cultivation rarely entailing sedentary farming. In this zone, land ownership is no longer exclusively communal. In southern Libya, isolated irrigated farming in the oases constitutes a third economic system with roots in the premodern era.
The most common mode of life in rural Libya is sedentary cultivation. In the oases most farmers rely on irrigation, and water is raised from shallow wells either by the animal-powered dalū (a goatskin bag drawn by rope over a pulley) or, increasingly, by electric or diesel pumps. Landholdings in the oases are small and fragmented; the average farm of five to seven acres (two to three hectares) is usually divided into three or four separate parcels. In the coastal regions, lowland farmers normally live on their own plots but enjoy rights to graze stock and undertake shifting grain cultivation on communally held land. In Cyrenaica and Tripolitania, most Arab farmers tend to live on plots of between 12 and 600 acres (5 and 240 hectares) that were once part of large estates belonging to Italian settlers.
Pastoral nomadism is practiced in the arid and semiarid regions, particularly in the Akhḍar Mountains and surrounding steppe lands in Cyrenaica. Nomadic groups subsist primarily on their herds of sheep, goats, and camels but also practice shifting cereal cultivation. These Bedouins move south as soon as pasture sprouts in the fall and remain there until the grasslands disappear and necessitate their return to the northern hills.
Fixed, permanently occupied villages were not typical features of nomadic life among the Bedouins of the Libyan steppe and desert, although towns have existed in the coastal zones since Phoenician, Greek, and Roman times. With the arrival of the Ottoman Turks in the 16th century, however, the new authorities founded towns and villages in the hinterland and desert that served as military posts or administrative centres; some of these sites have been occupied ever since. Other smaller, temporary settlements began as gathering places for nomadic tribes during periods of summer residence in the oases or in pastures in the hills. In the west, however, Amazigh populations are thought to have maintained a more or less continuous series of fortified nucleated villages in the western Nafūsah Plateau. In the southern oases, the villages served both as defense posts for the scattered communities and as watering and provisioning points on the trans-Saharan caravan routes. Since independence and the discovery of oil in the mid-20th century, economic development has led to the expansion of villages into towns and has attracted migrants from rural areas to these growing urban centres.
The two main cities are Tripoli and Benghazi. They contain about one-third of the country’s entire urban population and about one-fourth of the total population. Tripoli, with a metropolitan population of more than two million people, is the de facto political capital and the most important economic centre. Benghazi, with its metropolitan area of more than one million people, is the primary city in Cyrenaica. The modern cities have developed around the old city centres (medinas), with satellite towns and villages in surrounding oases. Shantytowns housing recent rural-to-urban migrants are also found near the two cities, although the government has built low-income housing.
Other important centres include Gharyān, Al-Khums, Misurata, Tājūrāʾ, Sūq al-Jumʿah, Janzūr, and Zawiyah in the west and Ajdābiyā, Al-Marj, Al-Bayḍāʾ, Derna, and Tobruk (Ṭubruq) in the east. These cities are primarily regional administrative and commercial centres with some light industry. Several have petroleum refineries and petrochemical installations.
Demographic trends
Libya’s rate of population growth is among the highest in North Africa. The influx of foreign workers into the country since the 1960s accounts for part of this rapid growth, but Libya’s annual rate of natural increase (birth rate minus death rate) has also been quite high. In the late 20th century and into the early 21st, death rates steadily declined to substantially below the world average, but birth rates remained relatively high. On the whole, Libya’s population is quite young: more than half of the population is younger than 30 years of age, with about one-fourth younger than 15. Libya’s infant mortality rate is the lowest in continental Africa and far below the global rate, portending continued rapid growth well into the 21st century.
