Cardinal Richelieu #

(1585–1642) French statesman, chief minister to Louis XIII from 1624 until his death. Entered France directly into the Thirty Years' War in 1635, leading the longest and ultimately decisive phase. ¹

Why It Was Strange #

France was the most powerful Catholic monarchy in Europe. The Holy Roman Emperor was the leading Catholic sovereign. By 1635, Richelieu allied France with Protestant powers (Sweden, the Dutch Republic, various German Protestant states) against the Habsburgs. He justified this as raison d'état — state interest transcending confessional alignment.

Method #

Direct French armies after 1635 were supplemented by immense subsidies to allied armies (Swedish, Dutch, German Protestant). The war became a grinding matter of resources the Habsburgs could not match long-term. See the French phase (1635–1648) on the Thirty Years' War page.
