1750 to 1945: the Enlightenment, four Atlantic revolutions, the factory, empire, two world wars and the Holocaust. Study cards, hints, a practice quiz at three levels, and four workshop activities that check themselves.
One thread is about RIGHTS — who rules, and by whose consent. 1776, 1789, 1804, the 1810s.
Two revolutions run through the whole period — one about RIGHTS, one about MACHINES. Every event in this unit is one of them, or the two colliding. When a question asks why something happened, ask first which thread it sits on.
What people get wrong
⚠️People often think…
The assassination of Franz Ferdinand caused World War I.
It was the TRIGGER. The causes are M‑A‑I‑N: militarism, alliances, imperialism, nationalism. Without those four, a single assassination is a crime; with them, it is a continental war in six weeks.
Trigger versus causes. Name all four.
⚠️People often think…
The Treaty of Versailles ended World War II.
Versailles is 1919 and ends World War ONE. Its terms are one of the standard explanations for why the second war happened — so putting it in the wrong war destroys the causal chain the question is testing.
Versailles 1919 ends the FIRST war.
⚠️People often think…
The Haitian Revolution came after the Latin American independence movements.
Haiti is 1804 and comes FIRST — and it matters that it did, because an enslaved population defeating a European army is what made the later movements seem possible. Order carries the argument here.
Haiti 1804, then Latin America.
⚠️People often think…
Lenin, Mussolini and Hitler all took power at roughly the same moment.
Sixteen years separate the first from the last: Lenin 1917, Mussolini 1922, Hitler 1933. And the gap matters — Hitler’s rise sits on the far side of the Depression, which is a large part of the explanation.
1917, 1922, 1933. The gaps do work.
⚠️People often think…
The Industrial Revolution mainly made life better for workers right away.
Output soared while wages, hours and city conditions stayed brutal for roughly two generations. The gains came later, and largely because of labor movements and reform laws — which is exactly where the two revolutions collide.
Output first. Wages and conditions much later.
⚠️People often think…
Naming two events and saying one led to the other is a complete answer.
A cause-and-effect answer has to supply the LINK — the mechanism in between. “Versailles led to Hitler” earns little; “Versailles imposed reparations that fed hyperinflation and humiliation, which extremist parties used” earns the point.
Give the middle, not the two ends.
Worth knowing cold
The dates worth knowing cold
One date, one event, in order. Learn the order and the missing one is usually obvious.
1776The American Revolution.
1789The French Revolution, thirteen years later.
1804Haiti wins independence — the only one of these led by enslaved people.
1810–25Latin America follows, country by country.
1914–1918World War I. The assassination is the trigger; M-A-I-N are the causes.
1917Lenin takes power in Russia — during the war, and Russia pulls out of it.
1919The Treaty of Versailles ends World War I — the FIRST war, not the second.
1922Mussolini takes power in Italy.
1933Hitler takes power in Germany — after the Depression, which is part of why.
1939Germany invades Poland. The war starts in Europe.
1941Pearl Harbor brings in the United States.
1945The war ends.
Ideas, revolts, factories, trenches, 1945
1Watch one
How did Versailles contribute to the Second World War? Give the link.
Start with what the treaty actually did: heavy reparations, lost territory, a war-guilt clause.
Name the effect inside Germany: economic crisis and a widely felt humiliation.
Name who used it: parties promising to tear the treaty up and restore standing.
Now the chain is complete — treaty, crisis, grievance, extremist opening. That middle is the answer. ✓

💬One sentence, then you move on
Why is a trigger not the same as a cause?
3Try one
Name the four causes of World War I that M-A-I-N stands for — give the first one.
I want a hint first
Building up armies and keeping war plans ready to go has a one-word name starting with M.
💬Last one — then you're done here
Why did the Industrial Revolution not improve workers’ lives right away?
Where this goes
Where this lives
Why a labor law exists at all, why borders in the Middle East and Africa run in straight lines, why the same arguments about rights and machines show up in a debate about automation today.
What this feeds
Next unit is human geography — where people ended up after all of this and why.
Name one right people argued for in this period that you still have.
One card at a time — tap “Show me” to check yourself, then Next. Start at Foundation; when those feel easy, climb.
Helpful Hints
🧭 The story in one line
Ideas (Enlightenment) → political revolutions (1776, 1789, 1804, 1810–25) → industrial revolution → nationalism and empire → World War I → a bad peace, a depression, dictators → World War II → 1945.
Two revolutions run through the whole period — one about RIGHTS, one about MACHINES. Every event here is one of them, or the two colliding.
⚠️ Traps the test loves
1776 American · 1789 French · 1804 Haiti · 1810–25 Latin America. In that order.
The assassination is the TRIGGER of World War I. M-A-I-N are the causes.
Versailles ended World War ONE. Do not put it in 1945.
Lenin 1917, then Stalin. Mussolini 1922, Hitler 1933.
Poland 1939 starts the war in Europe. Pearl Harbor 1941 brings in the United States.

🎯 How the test will ask
A timeline with one event missing.
A short document — “which Enlightenment idea is this?”
Cause and effect — “how did X lead to Y?” Always give the link, not just the two ends.
Compare two revolutions — one similarity, one difference.
A cartoon or poster — “whose point of view, and what does it want you to feel?”
✅ Before the test, can you…
Name three Enlightenment thinkers and one idea from each?
Put the four Atlantic revolutions in order and link each to the next?
Explain why industry began in Britain and what it cost the first workers?
Give the four M-A-I-N causes and the trigger?
Trace Versailles → Depression → Hitler?
Explain how the Holocaust advanced step by step?

Workshop
Work like a historian: put 170 years in order, sort the causes of a war, read a founding document clause by clause, then argue about a peace treaty.

This is your record of the module on screen — it stays here and goes nowhere. Independent means you got it right on the first tap; supported means you got it after the explain-and-retry, or marked ‘I had it’ on a revealed answer. Both count, and neither is a grade. If your teacher asks, copy the row or show them this screen.
