Passage: The revocation forbade Protestant services, required education of children as Catholics, and prohibited emigration. It proved disastrous to the Huguenots and costly for France. It precipitated civil bloodshed, ruined commerce, and resulted in the illegal flight from the country of hundreds of thousands of Protestants, many of whom became intellectuals, doctors and business leaders in Britain as well as Holland, Prussia, and South Africa. Four thousand emigrated to the North American colonies, where they settled in New York and Virginia, especially. The English welcomed the French refugees, providing money from both government and private agencies to aid their relocation. Those Huguenots who stayed in France became Catholics and were called "new converts".
How many French people fled to Prussia?
