In 1876, European powers controlled perhaps a tenth of the African continent, mostly coastal trading posts and a scattering of longer-established colonies. By 1914, they controlled essentially all of it, with only Ethiopia and Liberia remaining formally independent.
This rapid partition, known as the Scramble for Africa, was formalised at a conference held in Berlin from late 1884 into early 1885, called by Bismarck to manage rising tensions between European powers competing for African territory, and attended by representatives of fourteen European states and the United States. Not a single African ruler, state, or representative was invited or consulted.
The conference did not itself carve up specific borders in detail; that happened through subsequent bilateral treaties and on-the-ground military conquest over the following three decades. What it did establish was a set of rules for the competition itself: a European power could claim territory as its own sphere of influence if it notified the other powers and demonstrated effective occupation, meaning some actual administrative or military presence on the ground, a rule that triggered a rush of hurried expeditions specifically designed to plant a flag before a rival power could.
Europeans had known of Africa's coasts for centuries, and had traded there extensively, including in the slave trade examined in chapter thirty four, without attempting anything like full territorial conquest of the interior. Several factors converged in the 1870s and 1880s to change that.
Medicine mattered enormously. Quinine, derived from the cinchona tree examined in chapter twenty six's account of the biological exchange, became available in reliable, purified form by the mid nineteenth century, dramatically reducing European deaths from malaria that had previously made sustained inland expeditions extraordinarily costly in lives.
Technology mattered too. The Maxim gun, the first practical fully automatic machine gun, patented in 1884, gave small European forces a decisive and often overwhelming firepower advantage against much larger African armies equipped with older weapons, a gap in military technology considerably wider than it had been even a few decades earlier.
And industrial demand mattered. The industrialisation examined in chapter forty one created growing demand for raw materials, rubber, palm oil, and later minerals, that African territories could supply, alongside genuine, if often exaggerated, hopes of large captive markets for European manufactured goods.
Finally, the intensifying nationalist rivalries among the newly unified and expanding great powers, Germany and Italy chief among the newcomers examined in chapter forty three, made overseas colonial possessions a matter of national prestige and status as much as of direct economic calculation, a competitive dynamic in which each power's colonial gains were watched anxiously by its rivals.
European colonial rhetoric of the period rarely described the enterprise as simple conquest for material gain, however much that motive underlay it. Instead, colonisation was widely justified through a combination of arguments that reinforced each other.
A civilising mission, drawing selectively on Enlightenment universalism examined in chapter thirty three, claimed that European rule would bring modern government, education, Christianity and economic development to peoples characterised, in the period's own dominant racial theories, as backward or undeveloped, theories that drew on and extended the pseudo-scientific racial classifications already noted, in an earlier and less systematised form, in that same Enlightenment chapter.
Rudyard Kipling's 1899 poem, urging the United States to take up what he called the white man's burden in the Philippines, gave the justification its most quoted phrase, presenting colonial rule as a costly, thankless duty performed for the benefit of the colonised rather than the coloniser, a framing that found wide and largely uncritical acceptance among European and American reading publics of the period.
Economic arguments ran alongside the moral ones: colonies would supply raw materials unavailable at home, absorb surplus population through emigration, and provide captive markets for manufactured goods, arguments that appealed to industrialists and to the same emerging mass electorates whose support colonial parties increasingly needed to court.
The starkest case, and the one that most quickly exposed the gap between colonial rhetoric and colonial reality, was the Congo Free State, claimed as the personal private property, not of Belgium as a state but of King Leopold the Second of Belgium personally, following the Berlin Conference's recognition of his claim.
Leopold's administration, run for direct personal profit rather than through any formal Belgian state structure, extracted rubber through a system of forced labour enforced by mutilation, the severing of hands from workers and their children who failed to meet collection quotas, and mass killing on a scale that, once documented and publicised by missionaries, journalists and a British consular official named Roger Casement in the early 1900s, produced international outrage severe enough to force Leopold to cede control to the Belgian state in 1908.
Population losses in the Congo during Leopold's roughly twenty-three years of personal rule are estimated by historians at anywhere from several million to as much as ten million deaths, from direct violence, starvation caused by the diversion of labour from food production, and disease, though precise figures remain, as with several other cases in this book, genuinely disputed given the absence of any reliable population count either before or during the period.
The Congo scandal became, at the time, one of the first instances of a genuinely international humanitarian campaign, organised through pamphlets, photographs of mutilated survivors, and public meetings across Britain and the United States, forcing at least a change of administration, even if it did little to fundamentally alter the extractive economic logic that continued under direct Belgian state rule afterward.
African resistance to European conquest was constant and, in a small number of cases, successful, though the overwhelming pattern across the continent was eventual defeat given the technological and organisational gap described above.
Ethiopia is the clearest exception. Emperor Menelik the Second, having modernised his army with modern rifles and artillery purchased and imported specifically in anticipation of Italian ambitions in the region, decisively defeated an invading Italian army at the Battle of Adwa in 1896, forcing Italy to recognise Ethiopian independence and making Ethiopia the only African state to successfully repel a European colonial conquest attempt during this period, a victory that reverberated across the African diaspora and the wider colonised world as proof that European conquest was not, in fact, inevitable.
Elsewhere, resistance was crushed with a severity that, in several documented cases, meets modern legal definitions of genocide. German colonial forces in South-West Africa, present-day Namibia, responded to a rebellion by the Herero and Nama peoples in 1904 with an extermination order explicitly instructing that any Herero found within German territory, armed or unarmed, with or without cattle, was to be shot, and by driving surviving populations into the desert to die of thirst, killing, by most estimates, a substantial majority of the Herero population and a significant proportion of the Nama, in what many historians now consider the twentieth century's first genocide, predating by decades the atrocities examined in chapters still to come.
The German government formally acknowledged this as genocide only in 2021, and agreed to fund development projects in Namibia, though without using the specific legal term reparations, a settlement that Namibian representatives and Herero and Nama descendant communities themselves criticised as inadequate and reached without their own direct participation in the negotiations.
Beyond the famous atrocities, it is worth describing the more ordinary, everyday mechanics of colonial rule that governed most colonised Africans' actual daily experience.
Most European powers governed their African territories through a strategy historians call indirect rule, particularly refined by the British administrator Frederick Lugard in Nigeria: rather than replacing local political structures entirely, colonial administrations identified or, where none suited their purposes, invented compliant local chiefs and rulers, and governed through them, extracting taxes and labour while maintaining only a thin layer of European officials at the top.
This was cheaper than direct rule, requiring far fewer European administrators per head of colonised population than full direct governance would have needed, and it also let colonial powers claim they were respecting local custom and tradition, even where the specific chiefs empowered, and the specific version of custom enforced, were substantially colonial inventions rather than genuine continuations of pre-colonial governance.
Forced labour, in forms less extreme than the Congo's mutilation regime but still coercive, was widespread across the continent, including labour tax systems requiring a fixed number of unpaid working days per year from colonial subjects, ostensibly for public works like roads, and the practice, common in French and Portuguese territories especially, of conscripting African labour for private commercial plantations under conditions with only nominal legal distinction from the slavery that formal abolition, examined in chapter thirty four, had supposedly ended decades earlier.
European expansion in Asia during this same period followed a somewhat different pattern than the African scramble, building on colonial structures, British rule in India especially, that were already well established decades earlier, and typically involving more negotiated forms of control, protectorates and unequal trading treaties, rather than the full territorial annexation more common in Africa.
China, never formally colonised as a whole, was nonetheless subjected to a series of unequal treaties, forced open to European and, later, Japanese trade and influence after military defeats beginning with the Opium Wars examined in a later chapter, and divided into overlapping spheres of influence controlled by different foreign powers without any single power claiming full sovereignty.
This distinction between formal colonisation and informal, treaty-based domination mattered considerably for how these regions' subsequent histories unfolded, with formally colonised African and South Asian territories generally experiencing a different, and often longer, path to eventual independence than those, like China, that retained nominal sovereignty throughout even while losing substantial practical control over their own affairs.
Firm: the Berlin Conference's proceedings and rules, and the subsequent treaties and military campaigns of conquest, extensively documented in the colonial and diplomatic archives of every participating European power.
Firm: the Congo atrocities, documented not only by outside observers but by the colonial administration's own records, and by photographic evidence that proved unusually difficult for defenders of the regime to dismiss or explain away at the time.
Soft: population figures for the Congo and for the Herero and Nama genocide, as noted, given the absence of reliable population counts either before or during these events, a gap that is itself, in both cases, partly a product of the colonial administrations' own indifference to counting the populations they were governing and killing.
Contested: the overall balance sheet of colonialism's economic effects on colonised territories, a question that remains one of the most actively debated in economic history, with estimates of infrastructure built, resources extracted, and long-term developmental effects varying enormously depending on methodology and on which specific colony and period is examined.
A caution about scale and memory. This chapter has, of necessity, compressed the colonisation of an entire continent, with immense regional variation in method and consequence, into a single narrative organised around a handful of especially well-documented and especially severe cases. That compression should not be read as suggesting the Congo and Namibia were unrepresentative extremes rather than especially visible instances of patterns, forced labour, resource extraction, and violent suppression of resistance, that recurred, in varying degrees of severity, across most of the continent during this period.
