Revocation of the Edict of Nantes
Decided by Louis XIV, this revocation on October 22, 1685 led to the increased repression of Protestants (death sentences and sentences to row the galleys, forced conversion, etc.). It amplified the emigration of French Protestants to the so-called Refuge countries of Europe (Prussia, England, Switzerland, the Netherlands).
