The image of the burning cross is one of the most potent hate symbols in the United States, popularized as a terror image by the Ku Klux Klan since the early 1900s. Cross-burnings (called "cross-lightings" by Ku Klux Klan groups, to make it seem as if they are not destroying a Christian cross) have long been used as a traditional symbol by Klan groups, used both in Klan rituals as well as in attempts to intimidate and terrorize victims of Klan groups. So widely associated with racial intimidation has this symbol become that most criminal cross-burning incidents do not actually have a connection to a Ku Klux Klan group. The symbol of the burning cross has also transcended the borders of the United States, as tattoo images of Klansmen standing in front of burning crosses are not uncommon among European and other white supremacists.
