Henry IV of France.
Edict of Nantes
The Edict of Nantes was a bill issued on April 13, 1598, by King Henry IV of France which regulated freedom of religion in France for Protestants. When King Louis XIV revoked the Edict in 1685 it caused a massive emigration of the Huguenots (French Calvinists) from France to neighboring countries such as Austria, Germany, Holland, and England, where they were not prosecuted. Amongst these Huguenots were many skilled craftsmen who soon influenced the arts in their countries of refuge.
