The term Cargo cult refers to tribal societies the goods / cargo of first world countries as spiritual gifts. They sprouted after World War II, when the tribesmen came in contact with American soldiers. Eager to disconnect from European colonization and empowered by seeing black soldiers bringing the cargo, new religions began to emerge.
The most fascinating of the cargo cults is the John Frum Movement. Members worship an American serviceman named John Frum, said to have originated with a soldier identifying himself as “John, from America.” Annual tribe celebrations are held on February 15th – John Frum Day. A ceremonial army of men will paint U.S.A. on their chests and perform a hybrid dance / military drill with wooden guns. They will raise the American flag, build WWII airplanes out of grass, and build a makeshift landing strip, all with the expectation that John Frum will return with more cargo.
