The USI Six Dollar Note commemorates the House of War. In Islam, there are two Houses: the House of Islam (Dar al-Islam) and the House of War (Dar al-harb). By the time of the First Crusade, Islam had conquered lands from Lisbon to China, and from France to Africa. Christendom was fighting for its life against the fierce Sword of Allah.       The Three Dollar Note celebrates the Great Women of the Past. We see Betsy Ross, Mother of our Nation's Flag; Sacagawea, Trail Guide to the Lewis and Clark Expedition; and Susan B. Anthony, Champion of Women's Rights. We see them as they would be if they lived under Shari'a, the strict Islamic legal system.
