Cheerleading started as an all-male activity⁠⁠Cheerleading in the US can be traced back to the late 19th century, when male students rebelled and, besides taking part in riots, also started practising sports in universities. One of the earliest documented examples of cheerleading dates from 1877, happening at Princeton University. It’s only in 1923 that the University of Minnesota allowed women to join, and most universities followed much later, in the 1940s. By the 1970s, most cheerleaders were women.⁠
