In the United States one particularly virulent form of expression is associated with hatred and prejudice – the burning of a cross. Originally a traditional Scottish custom of signalling, following the American Civil War cross burning was adopted by guerrilla groups such as the Ku Klux Klan (Klan) as a symbol of racial supremacy and as a means of terrorising the newly freed slaves. The burning cross was glorified in the wicked movie The Birth of a Nation (1915) that depicted the Klan as heroes and saviors. Cross burnings were common at Klan rallies throughout the 1920s at a time when lynchings were commonplace and the Klan was at the height of its power. The burning cross was used as a warning and a threat to any person seeking to improve the political or economic condition of the black race.
