Bowling refers to a series of sports or leisure activities in which a player rolls or throws a bowling ball towards a target. It is one of the major forms of throwing sports. In pin bowling variations, the target is usually to knock over pins at the end of a lane. In target variations, the aim is usually to get the ball as close to a mark as possible.
The earliest known legislation against bowling dates to 14th Century England. The sport had become so popular that people were neglecting the archery practice necessary for national defense during the 100 Year War (a misnomer, since it actually lasted from 1337 to 1453).
