The Thirty Years' War

1618–1648

The Holy Roman Empire's religious and dynastic catastrophe

Begun as a Protestant revolt in Bohemia against Habsburg rule, it drew in Denmark, Sweden and finally France, and turned central Europe into a battlefield fought over by unpaid mercenary armies that lived off the country. By the time the treaties were signed in 1648 large parts of Germany had lost a third or more of their people.

What happened

Two imperial regents and a secretary thrown from a castle window in Prague, and surviving (23 May 1618)

Catholics said angels caught them; Protestants said they landed in a dung heap

The 'Winter King' who reigned in Bohemia for a single season (1619–20)

Frederick V of the Palatinate, son-in-law of James I of England

The Bohemian revolt crushed in an hour outside Prague, 1620

The sack of a great Elbe city in 1631, in which some 20,000 died

So notorious that 'magdeburgisieren' entered German as a word for total destruction

The 'Lion of the North' shot down in the fog at Lützen, 1632

Gustavus Adolphus of Sweden, killed at the moment of his side's victory

An overmighty mercenary generalissimo murdered by his own officers at Eger, 1634

Albrecht von Wallenstein, later the subject of Schiller's dramatic trilogy

A Catholic cardinal in Paris bankrolling, then joining, the Protestant side

Richelieu, for whom Habsburg encirclement mattered more than confession
