Chapter 45: Imperialism and the Modern World
Core idea
The largest empires the world has ever seen
By 1900, a handful of European powers and their settler descendants ruled most of the planet. The British Empire alone covered roughly a quarter of the world’s land and a quarter of its population — large enough that the sun never set on it. The French Empire ran from West Africa through Indochina to the Pacific. The Russian Empire, Dutch Empire, German Empire, Belgian Congo, Portuguese Angola and Mozambique, Spanish Caribbean, and the rapidly expanding empires of Japan and the United States filled in most of what was left. These were not loose trading networks. They were administrative, military, and economic structures designed to extract value from the colonised and transfer it to the colonising metropolis.
The Scramble for Africa was deliberate, fast, and brutal
In 1880, European powers controlled roughly ten percent of the African continent — mostly coastal trading posts. By 1914, they controlled almost all of it. The pace was the result of a deliberate diplomatic agreement: at the Berlin Conference of 1884-85, thirteen European powers and the United States divided Africa among themselves using straight lines drawn on inadequate maps, without consulting a single African leader. The lines cut through ethnic groups, watersheds, and trading networks; many became the borders of modern African states. King Leopold II of Belgium took personal ownership of the Congo Free State, where forced rubber collection killed an estimated ten million Congolese — a death toll comparable to the Holocaust.
Why it matters
Modern global inequality is a colonial inheritance
The wealthy economies of today and the poor ones of today did not arrive at their relative positions by accident. The same century that built industrial Manchester also drained raw materials and labour from Bengal, the Congo, the Caribbean, and the Andes. Infrastructure built in the colonies was designed to move resources to the coast for export, not to integrate national economies. Education systems trained clerks to serve the empire, not engineers to industrialise. The independence movements of the twentieth century inherited these distortions and have spent decades trying to undo them with uneven success.
Resistance was constant, not occasional
Colonial textbooks once portrayed European conquest as a procession of inevitable victories punctuated by occasional uprisings. The historical record is the opposite: every colonised territory produced sustained resistance — armed, legal, religious, and cultural. The Indian Rebellion of 1857, the Zulu victory at Isandlwana in 1879, the Ethiopian defeat of Italy at Adwa in 1896, the Boxer Rebellion in China in 1899-1901, the Maji Maji War in German East Africa from 1905, the Filipino-American War of 1899-1902, and dozens more were not peripheral events. They are the main story from the perspective of the people who lived through them.
Key takeaways
Key takeaways
- By 1900, European empires plus the United States and Japan controlled the overwhelming majority of the world's territory.
- The British Empire was the largest ever — about a quarter of the world's land — larger than Rome, Persia, or Alexander's Greece.
- The Berlin Conference of 1884-85 divided Africa among European powers using straight lines and no African representation.
- King Leopold II's privately-held Congo Free State (1885-1908) killed roughly 10 million Congolese through forced labour.
- Cecil Rhodes built personal fortune and political power in southern Africa, founding Rhodesia and articulating the era's most explicit white-supremacist imperialism.
- The British Raj governed roughly 300 million Indians from 1858 to 1947, extracting wealth while triggering devastating famines.
- Ethiopia under Menelik II defeated an Italian invasion at the Battle of Adwa in 1896, becoming the only African state to escape European colonisation.
- Independence movements inherited colonial borders, distorted economies, and the long task of rebuilding civic institutions.
Mental model
Read it as: Industrial demand and military technology in the metropolis combined with a diplomatic agreement (Berlin) to produce the direct-rule colonial system. Wealth flowed back to feed the same industry that needed the colonies; resistance and long-term distortion were the costs paid by the colonised.
Legacy
Cecil Rhodes and Belgian Congo: two faces of the same era
Cecil Rhodes used diamond and gold wealth to build a private empire across southern Africa, naming the colonies of Northern and Southern Rhodesia (now Zambia and Zimbabwe) after himself, and articulating the explicit racial supremacism that justified the entire imperial project. King Leopold II of Belgium ran the Congo Free State as personal property from 1885 to 1908, presiding over a system of forced rubber collection so brutal that even other European governments — themselves running colonial empires — eventually condemned it. The contrast between Rhodes’ polished colonialism and Leopold’s open atrocity is real, but the underlying logic is the same: territory, people, and resources existed to enrich the European metropolis.
Adwa and the limits of conquest
The Battle of Adwa on 1 March 1896 is one of the most important battles you may never have heard of. The Ethiopian emperor Menelik II organised a regional alliance, modernised his army, and met an invading Italian force in the highlands of northern Ethiopia. The Italians were routed; thousands died; Italy was forced to recognise Ethiopian independence. For the next forty years Ethiopia was the only African state never colonised. Adwa proved that European military supremacy was a function of organisation and weapons, not destiny — and it became a foundational reference point for twentieth-century African and Black diasporic political thought.
Example
Reading a colonial border
Look at a map of West Africa. Notice how many borders are perfectly straight lines, drawn at right angles, running for hundreds of kilometres through whatever happens to be there. The border between Mali and Mauritania, for instance, runs almost dead east-west for over a thousand kilometres, ignoring the fact that the same Tuareg and Soninke communities live on both sides of it. Now compare that to the borders inside Europe, where centuries of negotiation have produced lines that wander around rivers, mountains, and language groups.
The straight lines are the signature of the Berlin Conference. European diplomats with rulers and inadequate maps decided that a degree of latitude here, a meridian of longitude there, would mark the boundary between French and British, German and Belgian spheres of influence. When those colonies became independent states in the 1950s and 60s, they inherited the lines. The political consequences — divided peoples, contested borders, ethnic minorities scattered across multiple states — are not the natural geography of Africa. They are administrative artefacts of a meeting in Berlin in 1884 that no African attended.
