U.S. Department of Peace

"Our wise forefathers established Union and Amity between the Five Nations. This has made us formidable; this has given us great Weight and Authority with our neighboring Nations. We are a powerful Confederacy; and by your observing the same methods, our wise forefathers have taken, you will acquire such Strength and power. Therefore, whatever befalls you, never fall out with one another."
-Canassatego, the great Iroquois chief, advising the assembled colonial governors on Iroquois concepts of unity in Lancaster, Pennsylvania, 1744.
