Quick answers

Are the scores a ranking of nations or armies?

No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.

How many died?

About 15-22 million dead is the usual scholarly band, plus the 1918-19 influenza that killed tens of millions more worldwide, including many already weakened by the war. Military dead are better counted than civilians.

Why did it start?

No single cause. Alliance commitments, militarism, imperial rivalry, the Balkan crises, and a July 1914 diplomatic failure all appear in standard accounts. Historians still argue about German war aims and shared responsibility.

Why is the Western Front so famous in English?

That is where British, dominion and (from 1917) US armies fought longest. Poetry, photography and the density of cemeteries in France and Flanders created a portable memory. Other fronts were as deadly for those who fought there.

What was the Treaty of Versailles?

The 1919 treaty with Germany: territorial losses, disarmament clauses, Article 231 ("war guilt"), and reparations. It was one of several treaties. The US never ratified it.

Did tanks and aircraft decide the war?

They mattered increasingly in 1918, together with artillery-infantry methods and German economic collapse. They did not make 1916 "modern" in the later Second World War sense.

The Western Front's geography (coal, rail, Channel ports) locked both sides into a short, dense battlefield.

Gallipoli, the Isonzo, Palestine and East Africa had different climates and the same industrial logistics problem: how to supply a mass army far from home.

Principles

Alliance automaticity

Timetables and guarantees shortened the diplomatic hour in July 1914.

Defence stronger than attack

Until late methods caught up, attackers paid more -- a fact, not a slogan.

Economic war

Blockade and finance were grand strategy, not side policy.

Coalition command

Foch's 1918 generalissimo role was political as much as operational.

Peace needs enforcement

The League without the US, and with revisionist powers, could not police the map it drew.

Steps

  1. Regional crisis

    Sarajevo to Austrian ultimatum -- a Balkan war that could have stayed Balkan.

    Hindsight is cheap; the files show how narrow the exits were.

  2. General mobilisation

    Russian, German, French and Austrian mobilisations made reversal politically costly.

    Mobilisation was not yet shooting, but it was nearly war.

  3. Failed short war

    The Marne and the failure to outflank through Flanders ended the 1914 script.

    Plans are not destinies.

  4. Attrition years

    1915-17 offensives sought a break that geography and firepower denied.

    Learning was real and expensive.

  5. New belligerents

    Italy (1915), US (1917), and Russia's exit (1918) reset the coalition maths.

    Entry and exit both change strategy.

  6. Armistice politics

    Civilian governments sought terms while armies were still in the field.

    The clock on 11 November was a political instrument.

Limits

Civilian counts

Blockade deaths and Ottoman mass killings have wider error bands than British Army rolls.

Eastern Front neglect

English sources still under-describe 1914-17 in Poland and Galicia.

No employment guide

Trench and gas history is not instruction.

1918's combined-arms methods are described as history. They are not a field manual.

The "lions led by donkeys" slogan is a memory war, not a complete operational analysis.
