In 1891, the Missouri Tigers first faced off against the Kansas Jayhawks in the first installment of the Border War, which was also the oldest college football rivalry west of the Mississippi River until the teams stopped playing each other in 2012. The intense rivalry originally took place at neutral sites, usually in Kansas City, Missouri, until a new conference regulation was announced that required intercollegiate football games to be played on collegiate campuses. To renew excitement in the rivalry, ensure adequate attendance at the new location, and celebrate the first meeting of the two teams on the Mizzou campus in Columbia, Missouri, Mizzou Athletic Director Chester Brewer invited all alumni to "come home" for the game in 1911. Along with the football game, the celebration included a parade and spirit rally with bonfire. The event was a success, with nearly 10,000 alumni coming home to take part in the celebration and watch the Tigers and Jayhawks play to a 3–3 tie. The Missouri annual homecoming, with its parade and spirit rally centered on a large football game is the model that has gone on to take hold at colleges and high schools across the United States.
