The Ku Klux Klan robes and hood are similar to the Capirote that are worn by the Nazarenos (see Holy Week in Seville). The actual origin of the Ku Klux Klan robes are unclear, but similarity has caused confusion between the two with people who are unfamiliar with Holy Week.[1] Ironically the capirote has its origins in Catholicism, while the Ku Klux Klan is an anti-Catholic White Nationalist Protestant organisation.
