The term originated during the Spanish Civil War (1936–1939). A nationalist general, Emilio Mola, stated that four of his army columns were advancing on Madrid, while a "fifth column" (quinta columna) of sympathizers inside the city would rise up to support them. It has since become a standard term for any internal group working for an external enemy.
