See it on the Battles & Wars map →What happened
It began in 1754 in the Ohio Valley, where a young George Washington skirmished with the French, and in 1756 in Europe, when Frederick the Great of Prussia invaded Saxony. Austria wanted back the province of Silesia; Britain and France fought for colonies. Prussia survived near defeat when Russia's empress died in 1762 and her successor made peace. Britain took Quebec in 1759 and won Canada, Florida and the upper hand in India. Estimates vary, but roughly a million people died.
Why it matters
It made Britain the leading global power. The debt it left drove the taxes that sparked the American Revolution, and France's wish for revenge drew it into that war.
How we know
The 1763 treaties of Paris and Hubertusburg, rich government and military archives in Britain, France and Prussia, and letters of commanders such as Frederick, Wolfe and Montcalm.
Still debated
Whether it deserves Winston Churchill's label of the first world war, and how many died, especially of disease, remain debated.

Connections (3)
▸Line infantry, flintlock and bayonet fought the battles of Seven Years' WarWell documented
The connection
The Seven Years' War was fought largely by drilled lines of musket-and-bayonet infantry. Frederick the Great's Prussians, trained to fire faster than anyone, beat larger armies at Rossbach and Leuthen in 1757. In North America, British regulars in line broke the French on the Plains of Abraham at Quebec in 1759.
When and how
Rossbach and Leuthen in Germany, 1757; the Plains of Abraham at Quebec, 1759; armies of Prussia, Austria, France, Russia and Britain.
How we know
Battle reports, drill regulations and casualty returns from both sides describe linear formations and volley fire.
Debates and open questions
Whether Prussian success came from drill and rate of fire or from Frederick's flank attacks, such as his 'oblique order' at Leuthen, is debated.
▸Battle of Plassey was fought during Seven Years' WarWell documented
The connection
Plassey was part of the worldwide Anglo-French rivalry of the Seven Years' War. The French East India Company backed the nawab, and a small French artillery party fought on his side. Clive's victory, followed by British wins over the French in southern India at Wandiwash in 1760, ended French hopes of empire in India.
When and how
Bengal, June 1757, in the war's second year; Wandiwash and Pondicherry in southern India, 1760–1761, under Eyre Coote.
How we know
British and French company records show both sides treating Indian allies as part of the wider war; the 1763 Treaty of Paris confirmed the result.
Debates and open questions
How much Plassey depended on the European war, versus local Bengal politics and Clive's bribes, is debated.
▸Seven Years' War left debts and taxes that sparked American Revolutionary WarWell documented
The connection
The war nearly doubled Britain's national debt, to about £130 million. Parliament decided the colonies should help pay for their own defense and passed the Sugar Act (1764), Stamp Act (1765) and Townshend duties (1767). Colonists, no longer needing protection from French Canada, protested 'no taxation without representation.' The dispute escalated into war by 1775.
When and how
London and the thirteen colonies, 1763–1775; Prime Minister George Grenville's taxes and colonial protests such as the Stamp Act Congress.
How we know
Treasury figures, Parliamentary debates and colonial petitions document the debt, the new taxes and the protests that followed.
Debates and open questions
Historians debate whether the taxes were the real cause or a trigger for deeper splits over self-government, western land and trade.
