The Haitian zombie phenomenon first attracted widespread international attention during the United States occupation of Haiti (1915–1934), when a number of case histories of purported "zombies" began to emerge. The first popular book covering the topic was William Seabrook's "The Magic Island" (1929). Seabrooke cited Article 246 of the Haitian criminal code, which was passed in 1864, asserting that it was an official recognition of zombies. This passage was later used in promotional materials for the 1932 film "White Zombie".
