The idea was proposed by archeologist Hugo Winckler in 1901. It was widely propagated in the United States in the 1990s, first via the publication of Robert Morey's pamphlet The Moon-god Allah: In Archeology of the Middle East (1994), eventually followed by his book The Islamic Invasion: Confronting The World's Fastest-Growing Religion (2001). Morey's ideas were popularised by cartoonist and publisher Jack Chick, who drew a fictionalised cartoon story entitled "Allah Had No Son" in 1994.[3][original research?]
