“ The Pledge of Allegiance (1892) was the origin of the raised arm salute adopted later by the National Socialist German Workers Party (Nazis). The Pledge was written by Francis Bellamy, cousin to Edward Bellamy (the author), and both were self-proclaimed national socialists in the United States. The original Pledge began with a military salute that was then extended out toward the flag. In practice, the second gesture was performed palm down. The gesture was not an ancient Roman salute. All of these are discoveries of the symbologist Dr. Rex Curry (author of Pledge of Allegiance Secrets). ”
