The furnace lights
Around 1800, Britain began burning coal to spin cotton, pump mines, and drive looms — and output per worker broke from every historical ceiling. Why there first? Accessible coal, capital pooled from Atlantic trade, expanding markets, and a patent system that let tinkerers profit. The formula copied fast: railways, steamships, telegraphs, and factories remade every society they touched. Industrial power also remade war and empire — gunboats and railways let a small island administer a quarter of humanity, and the Scramble for Africa carved a continent at a Berlin conference table in 1884 with barely an African present.17
No single cause lit the furnace; coal plus capital plus markets did. And the furnace had a chimney: by 1900 coal smoke, colonial extraction, and breakneck urbanisation had already written the first drafts of our climate and inequality crises. Maps tell the story — 1914 Africa is nearly all colony, and 1914 Europe is an armed camp of alliances, timetables, and dreadnoughts waiting for a spark.

The wars that made the states
The First World War escalated because systems outran diplomacy: interlocking alliances, mobilisation timetables that punished delay, and empires that turned a Balkan assassination continental. Ten million soldiers died; three empires — Russian, Austro-Hungarian, Ottoman — collapsed outright. Russia’s collapse opened the door to 1917: war, hunger, and a disciplined Bolshevik minority made the first communist state, which would shape the century’s second half.
The Depression then showed what connection transmits: American banks fell, war debts defaulted, the gold standard seized, and unemployment marched worldwide — discrediting democracies and feeding fascists who promised order. The Second World War that followed killed perhaps seventy million, industrialised genocide included, and ended with the atomic bomb over Hiroshima and Nagasaki: war had learned to end cities in a flash, and everyone understood the next great-power war might end everything.18
Empires unwind, bombs keep the peace
After 1945 the colonial empires could no longer afford themselves — bankrupted by war and pushed by anti-colonial movements from Accra to Hanoi, they unwound with astonishing speed: India and Pakistan in 1947, dozens of African states around 1960. Agency plus exhaustion: the colonised pushed, and the metropoles could no longer hold.
Meanwhile the United States and the Soviet Union, each armed with weapons that made direct war suicidal, conducted their rivalry through proxies, spies, space races, and Olympic medal tables. The Cold War stayed cold where it mattered because the bomb moved war to the margins — Korea, Vietnam, Afghanistan bled instead. When the Soviet Union dissolved in 1991, the American-led order of markets, container ships, and the early internet inherited the earth. The shelf ends here, with you: the present is just the top layer of the excavation, still being laid down.
