Golf evolved from a game played on Scotland's eastern shore, near the royal city of Edinburgh. Originally, players would use a bent stick or club to smash a stone over sand dunes and over tracks. They would do this until they hit something worth playing - usually another rock - and then continue hitting that rock as hard as they could with their stick until it broke. In the 15th century, English nobleman William Caxton published The Game of Golf, which included illustrations of sticks with curved ends used by the time to play a form of catch with a ball. This may be the first book ever written about golf! Over time, the rules of golf changed to make the game more fun and less dangerous. For example, people used to be killed during games of golf because there were no rules against hitting someone with your club. In 1845, President Andrew Jackson signed into law an act that prohibited anyone from "aiming" a shot at another person's head, thereby making deathless sports like baseball and football possible. However, this law didn't stop people from trying to kill each other during games of golf; in fact, it increased the number of incidents dramatically. One reason for this is that people believed they could get away with murder on a golf course because no one would believe them if they got hurt.
