The six eras

SpanEraWhat holds power togetherLandmarks
c.3000 BC – 476 Ancient world Cities, writing, tribute and — with Rome — tax funding a professional army Pyramids, Parthenon, Caesar, Augustus, Jesus, Constantine
476 – c.1492 Medieval Land and personal loyalty; the Church as the only continent-wide institution Charlemagne, Al-Andalus, Crusades, Hastings, cathedrals, Black Death
c.1492 – 1789 Early modern Gunpowder states, oceanic trade, printed argument; centralising monarchies Columbus, Luther, Charles V, Armada, Thirty Years' War, Newton, Louis XIV
1789 – 1914 The long 19th century Nations, ideologies and industrial capital; European empires over most of the world Napoleon, railways, 1848, Darwin, unification of Italy and Germany
1914 – 1945 The catastrophe Industrial capacity turned on itself; mass mobilisation, total war Trenches, Russian Revolution, Depression, Spanish Civil War, WWII, Holocaust, atomic bomb
1945 – now Postwar & after Two non-European superpowers, nuclear stalemate, decolonisation, then one pole and globalisation Marshall Plan, NATO, Cuba 1962, decolonisation, 1968, Berlin Wall 1989, USSR ends 1991

Why each hinge is a hinge

476 — the Western Roman state stops functioning

Mechanism. Rome was a machine that taxed a huge integrated economy and spent the proceeds on a paid professional army. When the tax base and long-distance trade unravelled, there was no money to pay soldiers, so power reverted to whoever personally controlled land and the men on it. That is the whole of feudalism in one sentence.

What it is not. Not a single day of catastrophe, and not the start of a "dark age". Literacy, law and cities thinned out in the West but never vanished, and the Eastern empire carried on for another thousand years. Overview; the serious case is Chris Wickham, The Inheritance of Rome.

1492 — Europe's edge becomes the world's hub

Mechanism. Three things land within fifty years. Printing (c.1450) collapses the cost of copying an argument. Gunpowder artillery makes castles useless and favours whoever can afford cannon — that is, centralising kings. Ocean navigation turns the Atlantic coast from the dead end of Eurasia into the front door of a new trading system. Silver and plantations then finance European states for three centuries.

Fuzzy edge. 1453 (Constantinople falls to the Ottomans) and 1492 (Columbus sails; Granada falls; Jews expelled from Spain) are both used as the border. Treat 1450–1500 as a zone. Overview.

1789 — sovereignty moves from the king to the nation

Mechanism. Once legitimacy comes from "the people" rather than from God via a dynasty, the state can ask for things no monarch could: mass conscription, mass taxation, mass schooling in one language. Napoleon then demonstrates what a nation-in-arms can do to dynastic armies, and every European state has to copy the model or lose. Nationalism and ideology become the organising forces of the next two centuries.

Fuzzy edge. The American Revolution (1776) is the same wave, slightly earlier. Overview.

1914 — industrial capacity is turned on Europe itself

Mechanism. A century of industrial and administrative growth had built railways, factories, conscript reserves and rigid mobilisation timetables. Alliance obligations made mobilisation all-or-nothing, and industry made it sustainable for years rather than a season. The result is not a bigger war but a different kind of war — and the end of Europe's dominance of the world, whoever "won".

Read. Christopher Clark, The Sleepwalkers, on why no single villain explains it. Overview.

1991 — the bipolar order ends

Mechanism. 1945 left two superpowers outside western Europe, nuclear weapons making direct war unusable, and European empires bankrupt — hence decolonisation. That structure held for forty-five years; the Soviet economy could not sustain it. 1989 (the Berlin Wall) is the image, 1991 (the USSR dissolves) is the event.

The mechanism test — for when you don't know the date

Most events you meet will sit near a hinge, and you usually won't know the year. Don't ask which side of the date is this? — ask which mechanism was running? Work down the list and stop at the first line that fits.

Worked boundary cases. American Declaration of Independence — legitimacy from the governed, but a dynastic Europe all around it: leading edge of the 1789 wave, conventionally filed as late early modern. Say the mechanism, not the file. Spanish–American War (1898) — imperial competition without mass industrial mobilisation of society: long 19th, not catastrophe. Wall Street Crash (1929) — catastrophe, because it is one of the mechanisms producing the 1930s.

Two things to keep straight. First, hinges are zones, not lines: nobody woke up medieval. Second, this is a Western map. Chinese, Islamic and Indian history do not hinge on these dates, and using them there is a beginner's tell.
