North Africa

• 1. Introduction

  ›

  North Africa holds human remains that may push back the origin of our species by a hundred thousand years. At Jebel Irhoud in Morocco, researchers found some of the oldest Homo sapiens fossils yet discovered, challenging the long-held belief that modern humans arose solely in East Africa around 200,000 years ago. Those bones suggest our species was already spread across the length of the African continent far earlier than anyone expected. What does a region stretching from the Atlantic shores of the Western Sahara all the way to the Red Sea coast of Egypt and Sudan actually encompass? And how did a landscape that was once green and habitable become the largest sand desert on Earth, reshaping every civilization that tried to settle or cross it?

• 2. Borders Without Consensus

  ›

  Algeria, Egypt, Libya, Morocco, Tunisia, and Western Sahara form the core of the region as most commonly defined, though no single authority draws the boundary in exactly the same place. The United Nations extends that list to include Sudan, while the African Union swaps Sudan for Mauritania. At the edges, the question becomes stranger still: the Spanish cities of Ceuta and Melilla sit on the African continent, as do the Canary Islands, Madeira, and the Italian islands of Lampedusa and Lampione, all of which lie as close to Africa as to Europe, or closer. Western Sahara itself remains a live dispute between Morocco and the partially recognized Sahrawi Arab Democratic Republic, with control of the territory split between the two parties. That ambiguity at the border reflects something deeper about the region: North Africa has always been a zone of contact and contested definition rather than a sealed-off geographic unit.

• 3. Green Sahara, Deep Time

  ›

  Cave paintings at Tassili n'Ajjer, north of Tamanrasset in Algeria, show everyday life across central North Africa during the Neolithic Subpluvial, a wet period running from roughly 8000 to 4000 BCE. People, animals, and water appear in vivid scenes on rock faces that today overlook one of the most arid landscapes on Earth. Around 3500 BCE, a tilt in the Earth's orbit drove rapid desertification that transformed the region. Domesticated plants and animals had already arrived from the north and east in the 6th millennium BCE, and researchers have noted that grazing itself may have amplified the natural drying by spreading shrubs and open land across the terrain. Finds at Ain-Hnech in Setif push evidence of hominid occupation in North Africa back 2.6 million years; signs of Oldowan technology near Saida have been dated to as far back as 1.8 million BCE. The dry environment that followed 3500 BCE did not end human ambition in the region. It provided the backdrop against which dynastic civilizations formed and monuments like the Pyramids of Giza were built.

• 4. Carthage, Rome, and the Vandals

  ›

  Roman mythology traced Carthage's founding to Dido, a Phoenician princess said to have been granted only as much land as a piece of cowhide could cover, whereupon she cut the hide into thin strips to encircle a large territory. Whatever its origins, the city became a commercial empire spanning the Iberian Peninsula, Malta, Sardinia, Corsica, and the northwestern tip of Sicily. That last holding triggered the First Punic War with Rome. Over more than a hundred years, Rome eventually absorbed all Carthaginian territory, and the North African lands became the Roman province of Africa in 146 BC. The Numidian wars that followed launched the careers of both Gaius Marius and Sulla, and forced the Roman republic into a constitutional stretch: Marius needed a professional army, something previously contrary to Roman values, to defeat the military leader Jugurtha. The Kingdom of Mauretania held out until Emperor Claudius annexed it in 42 AD. North Africa proved indispensable to Rome as a grain-producing province; when Germanic Vandals crossed the Strait of Gibraltar in the early fifth century and seized it, the Western Empire lost both food supply and the revenue needed to rebuild armies. Rome's last serious attempt to retake the region came in 468 AD and failed. The last Roman emperor was deposed in 476 by the Heruli general Odoacer.

• 5. Arab Conquest and Arabization

  ›

  By 640, early Muslim conquests had reached North Africa. By 700, most of the region had come under Muslim rule. Indigenous Berbers responded by forming their own polities at places like Fez and Sijilmasa, and in the eleventh century a reformist movement, the Almoravid dynasty, pushed south into Sub-Saharan Africa. Arab migrations into the Maghreb began shortly after the initial conquest and continued in waves; the arrival of the Banu Hilal and Banu Sulaym in the eleventh century was particularly consequential. Ibn Khaldun recorded that the lands those invaders swept through had become completely arid desert. Historians mark that migration as a turning point in the Arabization of North Africa: as Arab nomads spread, the Zenata were pushed westward and the Kabyle people were forced northward into their mountains, where they managed to remain independent despite every successive occupier, from Romans and Byzantines through Vandals and Ottomans to the Arab conquerors themselves. The Berbers who did not retreat took refuge in highland terrain while the plains below were Arabized. A 2025 genetic study confirmed that the Arab migrations represented a major demographic shift involving genuine gene flow, not merely cultural replacement, and that both southern Qahtanite and northern Adnanite Arab tribes contributed to the Maghreb's population.

• 6. People and Languages Today

  ›

  Arabs today constitute the majority of the population in every North African country, making up between 92% and 97% of Libya and 98% of Tunisia. Berbers form a sizeable minority in Algeria, where they represent around 20% of the population, and in Morocco, where the figure reaches approximately 35%. Both Algeria and Morocco recognize Berber as an official language alongside Arabic. The most widely spoken dialects across the region are Maghrebi Arabic, a form of the language tracing back to the 8th century AD, and Egyptian Arabic. Arabic and Berber are distantly related, both belonging to the Afroasiatic language family, though the Tuareg Berber languages spoken in the Sahara have preserved older features that coastal varieties long since lost. Egypt's Coptic Christians, descendants of ancient Egyptians who shifted over centuries from varieties of Coptic to Egyptian Arabic, form the largest Christian denomination in the Middle East and North Africa. In 2001, an estimated 9 million Christians lived across the region, the majority in Egypt. The Jewish communities that once numbered around 500,000 across northern Africa, including Sephardi refugees from Spain, France, and Portugal dating to the Renaissance era, as well as indigenous Mizrahi Jews, largely emigrated to France or Israel after independence in the 1950s and 1960s. Today fewer than 3,000 remain in the region, concentrated in Morocco and Tunisia.

• 7. Geography and the Sahara

  ›

  Three features define the physical landscape of North Africa: the Sahara desert in the south, the Atlas Mountains in the west, and the Nile River and its delta in the east. The Sahara covers more than 75% of the region, making it the largest sand desert in the world. Its terrain is not uniform: ergs are vast seas of sand that build into enormous dunes; the hammada is a level rocky plateau stripped of soil; and the reg is a flat desert pavement. Irregular watercourses called wadis cut through the desert, flowing only after rain. The Atlas Mountains extend across northern Algeria, Morocco, and Tunisia as part of the fold mountain system that also runs through much of southern Europe, with the tallest peaks in the High Atlas range in south-central Morocco, where many summits hold snow. The Nile Valley, by contrast, threads a narrow fertile band along the length of Egypt, supporting crops including cereals, rice, and cotton; sheltered valleys in the Atlas and the Mediterranean coast grow olives, figs, dates, and citrus. The tallest peaks of the High Atlas remain snow-capped year-round, a striking contrast to the Saharan expanse that begins just south of the mountains.

• 8. Modern Upheaval

  ›

  From 1940 to 1943, North Africa was the setting for the North African Campaign of World War II. During the 1950s and 1960s, all North African states achieved independence. The Arab Spring, which began with revolutions in Tunisia and Egypt that toppled both governments, also brought civil war to Libya and large protests in Algeria and Morocco. Many hundreds died in those uprisings. Western Sahara remains disputed between Morocco and the Algerian-backed Polisario Front, a conflict rooted in the same post-colonial boundary questions that the region has carried since the earliest definitions of its edges were drawn. The Kabyle people, who resisted every empire that reached their mountains, still maintain a distinct presence in northern Algeria today.
