The first form of flintlock appeared in 1570 and was called a snaphaunce. About 1630, Frenchman Marin le Bourgeoys created the first "true" flintlock, also called the "French lock". Bourgeoys was in the service of King Louis XIII of France for whom he created the flintlock mechanism. The French lock simplified the Snaphaunce design by creating a one-piece, L-shaped frizzen. This is the style seen on most flintlocks today.
