The naming is itself contested and politically loaded. In Haitian Creole vodou refers to a particular rhythm and dance within the ritual repertoire; the religion as a whole has no single indigenous name, and practitioners say they serve the lwa, or serve with both hands, or sèvi Ginen. Voodoo, the English spelling, is largely a product of the American occupation of 1915 to 1934 and the sensational literature and films that followed, and it carries a set of associations — pins, dolls, curses, zombies — that Haitians do not recognise as descriptions of anything they do. Haitian and academic writing has largely settled on the Creole orthography Vodou for this reason, and the choice of spelling functions as a declaration of which account one is working from. The 1987 Haitian constitution and the 2003 decree both use the Creole form.
