The Carignan-Salières Regiment was a regiment of French troops who were sent to New France from 1665 to 1667 to fight the Haudenosaunee (Iroquois). These professional soldiers, who had little experience with fighting in the woods, invaded the lands of the Haudenosaunee but did not succeed in defeating them. Nevertheless, the French show of force led to a peace accord in 1667. Though most of the French soldiers then went home, some stayed, married and settled in New France. Many of them married Filles du Roy and now have many descendants. Quebec municipalities such as Berthier, Chambly and Verchères still bear the names of officers of this regiment.
