The "Dragonnades" were a French government policy instituted by Louis XIV in 1681 to intimidate Huguenot families into either leaving France or re-converting to Catholicism. This involved the billeting of ill-disciplined dragoons in Protestant households with implied permission to abuse the inhabitants and destroy or steal their possessions. The soldiers employed in this role were satirized as "missionary dragoons".
With the revocation of the Edict of Nantes in 1685, Louis XIV withdrew the privileges and toleration that Protestant Huguenots in France had been guaranteed under the edict for nearly 87 years, and ordered the destruction of Huguenot churches and the closure of Huguenot schools.
Following the revocation of religious toleration, 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 to 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.
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.
