Assyria and Germany in Anglo-Israelism
Edward Hine originated the notion, still current in Anglo-Israelism and some strains of U.S. Christian fundamentalism, that modern Germans are partly descended from the ancient Assyrians. In this belief system, the British are the sole descendants of the Ten Lost Tribes of Israel, in opposition to other Anglo-Israelism advocates who included Germans in the lost tribes.
