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?

In the Holy Roman Empire, about 4-8 million is a working band -- a huge share of some territories. Battle deaths were a minority beside famine and disease.

Was it only a religious war?

It began as a Bohemian and imperial confessional crisis. It became a European great-power war, especially after France entered against the Habsburgs.

What was Westphalia?

Two 1648 treaties that resettled religion and imperial constitution and involved France and Sweden as guarantors. Later "Westphalian sovereignty" is a simplified teaching story.

Who was Gustavus Adolphus?

King of Sweden, victor at Breitenfeld (1631), killed at Lutzen (1632). He made Sweden a Baltic great power and a Protestant military model in later myth.

Why is English memory thin?

England was not a main belligerent (though it had earlier Palatine ties). The war left no poppy ritual in London. Germany kept the demographic scar.

Start with this section - Legacy

The Empire survived, weaker. France and Sweden gained. The Dutch Republic's independence was recognised.

The later "Westphalian system" idea shaped how twentieth-century diplomats talked -- a legacy of reading, not only of 1648.

Lessons

Civilians can be the main battlefield

Contributions made villages into magazines.

Patrons change the war they join

Sweden and France did not fight Bohemia's original war.

Exhaustion can settle more than victory

1648 is a peace of cannot-continue.

Beware theory labels

"Westphalian" is a later tool.

Local records beat slogans

Parish books are the honest monument.

Unresolved

Territory-by-territory demography

Still being refined.

Wallenstein's last politics

Conspiracy files remain argued.

Art restitution

Some church loot trails never closed.

The IR myth in teaching

A pedagogical habit that historians keep correcting.

Shifts

Sweden's great-power season

A seventeenth-century Baltic order.

French anti-Habsburg edge

A step toward later Louis XIV wars.

Imperial constitutional lock-in

Fragmentation confirmed.

A language of statehood

Later lawyers' Westphalia -- a shift in books, then in diplomacy.

Outlook

Local history boom

German regional studies still move the death map.

IR courses may adjust

Some already teach "Westphalia myth" as the unit.

A closed war, an open metaphor

The fighting ended; the sovereignty slogan did not.

Risk

22 / 100
closed, mis-taught

The war is historically closed. The live risk is pedagogical: using "Westphalia" as a cartoon of 1648, or forgetting the German dead in a theory lecture.

German unification much later had to overcome the political map Westphalia confirmed.

Religious coexistence in the Empire was legalised exhaustion, not liberal tolerance in a modern sense.
