By 1921, football became a major part of ISU tradition when football replaced basketball as the featured Homecoming game. Originally starting out as small event with banquets and a featured basketball game for alumni and current student, Homecoming eventually came to include the election of Homecoming queens by 1937, the parade in 1923, bonfires from the 1930s to the 1990s, the trike race in 1963, and the Miss Ebony Pagaent since 1974.
The Blue and White Parade became an especially important tradition tied to the Homecoming and football tradition. Fraternities, sororities, dorms, student organizations, and even departments on campus created floats while staff and university administrators, like the president, often marched or drove in what is one of the longest running student organized homecoming parades in the nation. While the Student Homecoming Committee eventually adopted a theme for each year, floats often incorporated references to the Homecoming football game.
