In the 1920s, the Ku Klux Klan promoted negative characterizations of Columbus in order to vilify Catholics and immigrants, many of whom celebrated Columbus not only as a source of ethnic and religious pride but also as a symbol of the free and diverse society that resulted from the European presence here. The Klan tried to prevent the erection of monuments to the Great Navigator, burned crosses in opposition to efforts to honor him, and argued that commemorations of his voyage were part of a papal plot. Rather than honor a Catholic explorer from the Mediterranean, Klansmen proposed honoring the Norseman Leif Eriksson as discoverer of the New World and a symbol of white pride.
