Bows are used for hunting, for sport (see archery), and still occasionally for war. The development of gunpowder and muskets, and the growing size of armies, slowly led to the replacement of bows as weapons of war.
The technique of using a bow is called archery. Someone who makes bows is known as a bowyer, and one who makes arrows is a fletcher.
