The Ku Klux Klan began after the Civil War as a way for the southern states to combat all the free black people that were now in their cities. By the early 1900s, the Klan had mostly died out, but it rebirthed in 1915, partially thanks to a movie that depicts the Klan as a supporter of order and justice (Tucker 53). In Indiana, the membership skyrocketed, giving Indiana the largest membership of any state in the country (Tucker 59). The Klan opposed all immigrants, especially Catholic ones, and by doing this they were shown as a supporter of Americanism (Tucker 58). In addition, the Klan supported Prohibition, seen as a law against immigrants who consumed alcohol, and they offered a way to protect against labor unrest (Tucker 57). By 1924, the students of Notre Dame were fed up with the lies and rumors that the Klan was spreading about Catholicism (Tucker 123). On May 17, 1924, they proved that the Klan did not belong in South Bend ("Klan Display..." 1). By driving the Klan from the city, the students were having a revolution against the Ku Klux Klan ("Klan Display..." 1).
