Excerpts from Books and Wikipedia
"The Edict of Fontainebleau revoked all the privileges that Louis's grandfather Henry IV had granted to Protestants (Huguenots) in the edict of Nantes in 1598. It ordered Huguenot ministers to be banished, schools closed, places of worship destroyed, and children born to Huguenot parents baptized as Catholics. . . . Although the Edict of Fontainebleau formally denied Huguenots permission to leave France, between 200,000 and 500,000 (about half the total number of Protestants) fled the country." [1001 Days]
