By the thirteenth century, the Mali Empire had succeeded Wagadu as the dominant power of the western Sudan, consolidating much of the region under one ruler. Mali's most famous ruler, Mansa Musa, made a pilgrimage to Mecca in 1324 that became legendary across the medieval world for the sheer quantity of gold his caravan distributed. Then came the Songhai Empire: a local leader named Sonni Ali seized the great city of Timbuktu in 1468 and built a regime on trans-Saharan trade. His successor, Askia Mohammad, made Islam the official religion, built mosques, and brought scholars to the capital at Gao, turning it into a centre of learning.

Along the West African coast, far from these Sahelian empires, independent kingdoms developed in the forest zones with little outside influence. The Kingdom of Nri, one of the oldest in present-day Nigeria, was already established by the ninth century and is celebrated for its elaborate bronze sculptures found at the town of Igbo-Ukwu. The Kingdom of Ife followed, the first of the Yoruba city-states, ruled by a priestly king called the Ooni. Ife's tradition of naturalistic bronze sculpture was among the most sophisticated in the medieval world.

In the north, Arab and Berber cultures were fusing under the unifying framework of Islam. The Almoravids, a Berber dynasty from the Sahara, swept across northwest Africa and into Spain in the eleventh century. Waves of Arab migrants moved westward from the Arabian Peninsula, their arrival reshaping the languages and cultures of the Maghreb, blending with existing Berber populations in a process that took several centuries.

CHAPTER: The Wound That Would Not Heal The fifteenth century brought a catastrophe whose consequences the continent is still living with. Between 1400 and 1900, an estimated seven to twelve million people were taken from Africa across the Atlantic to work as enslaved labourers in the Americas. The scale requires holding in mind: across roughly four centuries, the equivalent of every person in present-day Portugal was torn from their home and transported across an ocean, never to return.

The trade reshaped the political map of West Africa. Coastal kingdoms that sold captives to European traders grew powerful; others were devastated. The Asante Confederacy and the Kingdom of Dahomey became major players in the trade, accumulating wealth and weapons in exchange for human beings. The Oyo Empire, one of the great powers of the region, eventually proved unable to adapt when the trade began to decline in the 1820s and collapsed into civil wars.

The Atlantic trade was not the only forced movement of people. The trans-Saharan slave trade had moved enslaved Africans into North Africa and the wider Islamic world for centuries before the Europeans arrived. In total the numbers taken through all slave trades from Africa run into the tens of millions. The demographic and psychological wound this left on African societies was deep and long-lasting, and scholars have argued it is one of the reasons many regions remained vulnerable to what came next: colonial conquest.

European colonisation began in earnest in the late nineteenth century, driven by the Second Industrial Revolution and the hunger for raw materials it created. Between roughly 1880 and 1914, European powers carved the continent into territories at a conference in Berlin, drawing borders with rulers and straight lines that cut through ethnic homelands, split peoples between colonies, and lumped together communities with no shared history or language. Of the fifty-four countries in Africa today, the borders of almost all of them were drawn by people who had never set foot on the continent.

The exceptions to this colonisation were two: Ethiopia, which defeated an Italian invasion at the Battle of Adwa in 1896 and maintained its independence, and Liberia, established as a home for freed American slaves and recognised by the European powers. Every other territory on the continent was brought under European rule, administered for the purpose of extracting resources and labour, with little investment in education, infrastructure, or governance for the benefit of the local population.

CHAPTER: Independence and Its Aftermath World War Two changed everything. The European powers emerged from it weakened and indebted, and the moral case for empire had been corroded by the war against fascism. Independence movements gathered momentum across the continent. Libya broke free from Italian rule in 1951. Tunisia and Morocco won independence from France in 1956. Ghana became the first sub-Saharan colony to gain independence in March 1957, and its first leader, Kwame Nkrumah, became a symbol of the pan-African dream.

What followed was one of the most dramatic political transformations of the twentieth century. The year 1960 became known as the Year of Africa: seventeen countries gained independence in that single year alone. By 1963, enough new nations existed to found the Organisation of African Unity, which brought together the newly independent states in Addis Ababa under a shared commitment to sovereignty and cooperation. Portugal held on the longest, its colonies in Angola, Mozambique, and Guinea-Bissau finally freed in 1975 after a military coup ended the regime in Lisbon itself.

The transition to independence, however, brought enormous challenges. Colonial rule had deliberately underdeveloped the territories it controlled, suppressing local industries, extracting resources without reinvesting them, and governing through division rather than unity. The new nations inherited economies built to serve Europe, bureaucracies staffed mostly by foreigners who had just left, and borders that made geographic but not political sense. Most of their populations were living in extreme poverty.

Political instability followed quickly. A majority of African countries experienced military coups or periods of dictatorship during the 1960s, 1970s, and 1980s. Many leaders exploited ethnic divisions that colonial rule had entrenched or created, using them to consolidate power. The results were sometimes catastrophic. The Nigerian Civil War in the late 1960s ended in a famine that killed between one and two million people. Two civil wars in Sudan, stretching from 1955 to 2005 with a brief pause between them, killed around three million, fought largely along ethnic and religious lines.

Cold War rivalry added another layer of suffering. The United States and the Soviet Union competed for influence across the continent, propping up aligned governments regardless of their brutality. The Angolan Civil War became a proxy conflict, with Soviet and Cuban forces supporting one side and American support flowing to the other. When the Cold War ended and foreign aid dried up abruptly, the countries most dependent on it went into severe economic and political crisis.

Two events in the 1990s stand as the starkest reminders of how badly things could go wrong. Between 1983 and 1985, a famine in Ethiopia killed up to one and a half million people, caused not simply by drought but by the forced relocation of farmers and grain seizures by a communist military government. Then in 1994, in Rwanda, a genocide organised along ethnic lines between Hutus and Tutsis killed up to 800,000 people in roughly a hundred days. The international community watched and did not intervene. The genocide destabilised the surrounding region and contributed to the outbreak of the Congo Wars, which over the following decade killed an estimated five and a half million people, making them the deadliest conflict anywhere in the world since World War Two.

Yet the full story does not stop there. From the late 1990s onwards, and accelerating through the 2000s, much of the continent began to change. Civil wars ended in Angola, Sierra Leone, Liberia, and Sudan. Market reforms spread. Foreign investment, much of it from China, flowed in. Between 2000 and 2014, annual economic growth across sub-Saharan Africa averaged more than five per cent a year, and the continent's combined output roughly doubled. Mobile phone adoption spread faster in Africa than anywhere else on Earth, connecting millions of people to markets and information for the first time.

The political picture also shifted. Botswana and Mauritius maintained unbroken democratic governance throughout their post-colonial histories, rare examples of stability that demonstrated what was possible. Many other countries moved toward more open systems during the 1990s and 2000s. Women's political representation in Rwanda, driven partly by post-genocide reconstruction efforts, reached levels that most of Europe and North America had not achieved. Young people, who make up the majority of the continent's population, the median age still well below thirty, became the drivers of cultural and economic change.

Challenges remain enormous. Conflicts continue in Sudan's Darfur region, in the Lake Chad basin where the Boko Haram insurgency has killed around 350,000 people since 2009, and in parts of the Sahel where instability has spread in recent years. Climate change poses a threat the continent did little to create but is already suffering most severely: the United Nations has identified Africa as the continent most vulnerable to its effects, with desertification, water scarcity, and extreme weather already displacing communities and undermining harvests.

What does not change is the underlying fact with which this story began. Africa is where the human species was born. Every lineage on Earth, traced far enough back, leads to the eastern grasslands of this continent. In a meaningful sense, the history of Africa is not a chapter in human history. It is the book that all the other chapters are written inside.
