The Dragonnades was a policy implemented by Louis XIV in 1681 to force French Protestants known as Huguenots to convert to Roman Catholicism. It involved the billeting of dragoons of the French Royal Army in Huguenot households, with the soldiers being given implied permission to mistreat the inhabitants and damage or steal their possessions. Soldiers employed as part of this policy were derisively referred to as "missionary dragoons".

With the Edict of Nantes in 1598, Henry IV of France ended the French Wars of Religion by granting a relatively high degree of toleration to French Protestants (known as Huguenots) as well as political and military privileges. The latter were abolished in 1629 under the Peace of Alès following the Huguenot rebellions, but the provisions of the Edict of Nantes granting religious tolerance were largely maintained under the governments of Cardinal Richelieu and Cardinal Mazarin.

Louis XIV, however, aimed to have religious uniformity in his kingdom. Initially he offered the Huguenots financial incentives to convert, but this had limited effect. By the late 1670s he decided upon a harsher policy. He began to order the destruction of Huguenot churches and the closure of Huguenot schools.

Louis XIV combined legal persecution with a policy of terrorizing recalcitrant Huguenots who refused to convert to Catholicism by billeting both dragoons and ordinary infantrymen in their homes. The soldiers were instructed to harass and intimidate the occupants, in order to persuade them to either convert to the state religion or emigrate. As mobile mounted infantry, the 14 regiments of dragoons in the French Army of the period were sometimes used for what would now be called internal security duties, and were an effective instrument for persecuting the Huguenots.^[1]

The application of selective and coercive troop quartering had been initiated by the intendant René de Marillac in Poitou, in 1681. With the permission of the Secretary of State for War François-Michel le Tellier, Marquis de Louvois, Marillac systematically lodged troops with Protestants, in the expectation that existing laws exempting households newly converted to Catholicism from this practice would spur conversions. Billeted troops got so far out of hand that, after a series of reprimands in letters, the Marquis de Louvois was forced to recall Marillac from Poitou.^{[note 1]} The Marquis himself was to be subsequently blamed for originating the dragonnades but research has established that responsibility rested with more junior officials such as de Marillac, ambitious for royal favour. Louvois did not oppose the policy but was concerned with the negative impact on the discipline of the soldiers involved.^[2]

The persecution of Protestants caused outrage in England and created a wave of literature in protest against the inhumane treatment of Huguenots, thousands of whom fled to England to seek asylum. The dragonnades caused Protestants to flee France, even before the Edict of Fontainebleau of 1685 revoked the religious rights granted them by the Edict of Nantes. Most Huguenot refugees sought refuge in countries such as Switzerland, the Dutch Republic (from where some migrated to the Cape Colony in southern Africa), England, and the German territories (notably Brandenburg-Prussia). Smaller numbers also fled to New France, the British colonies in North America, or Lutheran Scandinavia. Huguenots also fled to Brazil, where they founded the city of Saint-Louis-de-Maragnan (present-day São Luís, in the state of Maranhão), which is the only Brazilian capital founded by the French. Today among the remnants of the French Huguenot colonization of the city, there is a museum dedicated to the Huguenots, and the place where the Huguenots built a fort has become the city hall, but retains its original name of La Ravardière.

On 17 January 1686, Louis XIV claimed that his policies had caused the Protestant population of France to decline from 800,000–900,000 to 1,000–1,500. Though he greatly exaggerated, their numbers did decline significantly.^{[citation needed]} According to Hans J. Hillerbrand, an expert on Protestantism,^{[citation needed]} Huguenot numbers had been steadily declining since the St. Bartholomew's Day massacre in 1572.^{[citation needed]} The campaign ultimately proved detrimental to France's economy, as many were part of the nascent urban bourgeoisie and many others possessed skills such as silkweaving, clock-making, silversmithing, and optometry. ^{[citation needed]}
