Chapter 55: Twilight of Empires
Core idea
The fastest unmaking of empire in history
In 1900, the Austrian cartographer Alexander Supan calculated that Europe and the European-founded United States together controlled 62.5 percent of the planet’s habitable land surface — 100 percent of Australia and Polynesia, 90 percent of Africa, 57 percent of Asia. By 2000, that figure was a rounding error. The British Empire alone collapsed from 13.7 million square miles in 1920 to the 122,000-square-mile British Isles by the late twentieth century. No empire in recorded history had ever lost so much territory so fast, and no continent had ever swung from dominance to ordinariness in a single century.
The wave was inevitable, the form was not
The pressures that brought down the European empires were structural: two world wars had bankrupted the colonial powers, industrialization had spread to their subject populations, anti-colonial ideologies (Marxist, nationalist, religious) had become widely available, and the new superpowers (the US and USSR) had reasons of their own to dismantle the old imperial order. The collapse was over-determined. But how each colony left — peacefully via referendum or violently via insurgency, with partition or intact, with a functioning state or not — varied enormously, and that variation shapes the political map of the present day.
Why it matters
Independence is the easy part
The headline date — 1947 for India, 1957 for Ghana, 1960 for Nigeria — marks the moment the flag changed. What it does not mark is the moment the colonial economy was rewritten, the moment ethnic boundaries drawn by colonial administrators stopped causing wars, or the moment former subject populations developed the institutions a working state requires. Many of the most painful post-1945 conflicts — the India-Pakistan partition, the Algerian war, the Congo crisis, the Biafran war, the Rhodesian bush war — were direct consequences of how the imperial powers chose to leave. The bill for empire kept coming due long after the colonizers had checked out.
Suez 1956: the moment Britain knew
When Egyptian president Gamal Abdel Nasser nationalized the Suez Canal in July 1956, Britain, France, and Israel responded with a coordinated invasion. They expected the United States to back them as it always had. Instead, President Eisenhower forced a humiliating withdrawal by threatening to crash the pound sterling. The Suez Crisis is often called the moment the British Empire ended in fact, even though most of the formal independence dates came later. After Suez, every colonial power knew it could no longer act without American permission, and American permission for colonial adventures was no longer available.
The intellectuals of liberation
Decolonization produced its own theorists. Frantz Fanon, a Martinican psychiatrist who served with the Algerian FLN, wrote The Wretched of the Earth (1961) — an unflinching argument that colonialism could only be undone by violence because it had been imposed by violence, and that the psychological damage of being colonized had to be confronted before independence could mean anything. Patrice Lumumba, the first elected prime minister of the Congo, was assassinated in 1961 by a coalition of Belgian, American, and Congolese forces who feared he would steer his country into the Soviet orbit. His death became a symbol across Africa of how thin “independence” could be when the old powers and the new superpowers preferred a compliant successor.
Key takeaways
Key takeaways
- In 1900 Europe and the US controlled about 62.5 percent of the world's land; by 2000 almost all of that was lost to independence movements.
- Indian independence in 1947 created India and Pakistan and produced one of the deadliest partition crises of the twentieth century.
- The 1956 Suez Crisis exposed Britain and France as unable to act militarily without American consent — the unofficial end of European imperialism.
- Most British African colonies became independent in a single decade (1957-1968), driven by local movements, US-Soviet pressure, and British exhaustion.
- Frantz Fanon argued that colonial violence could only be undone by counter-violence and that psychological liberation had to accompany political liberation.
- Patrice Lumumba's assassination in 1961 showed that formal independence was no protection if Cold War powers preferred a different leader.
- Earlier revolts — the American Revolution, Toussaint Louverture's Haitian Revolution, Bolívar's South American campaigns — proved that empires could be defeated long before the twentieth-century wave.
Mental model
Read it as: Four independent pressures converged on every European empire at once. The result — independence — was nearly inevitable, but the path (negotiated vs. violent) varied, and the aftermath was rarely as clean as either path suggested at the time.
Legacy
The decolonization wave reshaped the international system more thoroughly than any event since the fall of Rome. The United Nations grew from 51 founding members in 1945 to 193 today, almost all of the new members former colonies. The Non-Aligned Movement, founded at Bandung in 1955, gave the new nations a collective voice independent of both Cold War blocs. The global economic geography we live with — Indian software exports, Nigerian oil politics, the modern Commonwealth, the ongoing tensions between former metropoles and former colonies over migration and reparations — is the direct sediment of how the European empires ended.
Example
A line on a map: the Radcliffe Line
In July 1947, the British government gave Sir Cyril Radcliffe, a London lawyer who had never visited the Indian subcontinent, five weeks to draw the border between the new states of India and Pakistan. He was working from outdated maps and incomplete census data. The line he produced cut through villages, separated farms from wells, and sliced the Punjab and Bengal in half.
Within months, an estimated 10 to 20 million people were displaced and somewhere between 200,000 and two million killed in communal violence as Hindus fled west and Muslims fled east across his line. Radcliffe burned his papers, refused his fee, and never returned to the subcontinent. The Kashmir conflict that the line failed to resolve has produced four India-Pakistan wars and continues to be one of the most dangerous nuclear flashpoints on Earth.
The lesson is general. When an empire withdraws in haste, the borders it leaves behind tend to outlast it — and the people who actually live near those borders pay the cost for generations. Most of the world’s “frozen” conflicts (Cyprus, Kashmir, Palestine, Western Sahara) trace back to decisions made by departing colonial administrators with incomplete information and short deadlines.
