In the 12th century the game became extremely popular in England. In fact it became so popular that some kings would ban it so that people should play the other traditional sports. However that didn't help too much and it continued to gain popularity. Seven schools soon adopted the game however rules had to be enforced. Six of the seven schools worked together and formed the same rules. The seventh school "Rugby" enforced its own rules and regulations. They had a crossbar that was 10 feet off the ground that the ball had to pass over and they also added a few goal posts.
