Find the best cheerleading lessons, classes, and instructors at HeyKiki and learn the sport of cheerleading. When you think of cheerleading you might think of a team of mostly women in uniform performing stunts and routines during a football game. You might be suprised to find out that when cheerleading first started (around the same period American football originated), women were not allowed to be on the teams; it was all men! In the 1920s women began joining the cheer teams, but it wasn't until the 1940s when there were more full women teams because during this time, WWII called for most men to go to war. What a history!
