Approximately 900,000 French Protestants, known as Huguenots, fled France during the 1680s to escape religious persecution [1].

This migration represents a pivotal moment in European history, as the loss of a skilled population altered the economic and social landscape of France while strengthening the states that welcomed the refugees.

The exodus followed the revocation of the Edict of Nantes in 1685 [1]. This legal shift removed the protections previously granted to Protestants, leading to a period of state-sanctioned violence and oppression ordered by King Louis XIV [1].

Many of the displaced Huguenots sought refuge in various Protestant states across Europe [1]. Prussia became a notable destination for these refugees, who sought safety and the freedom to practice their faith away from the French monarchy [1].

ARTE said the movement was a "retour sur l'exode des protestants français, notamment vers la Prusse, afin d’échapper aux persécutions instiguées par Louis XIV après la révocation de l'édit de Nantes, en 1685" [1].

The scale of the migration was significant, with roughly 900,000 people affected by the shift in policy [1]. These individuals faced a "leap into the unknown" as they abandoned their homes to avoid the consequences of the king's mandates [1].

Prussia's willingness to accept the Huguenots provided the state with an influx of experienced artisans, and intellectuals [1]. This migration pattern shifted the demographic and religious balance of the region during the late 17th century [1].

Approximately 900,000 French Protestants, known as Huguenots, fled France.

The revocation of the Edict of Nantes illustrates the impact of state-mandated religious uniformity on national stability. By forcing a mass exodus of nearly one million citizens, France experienced a significant 'brain drain' of skilled labor and capital, while receiving states like Prussia gained immediate economic and intellectual advantages.
