In order to counter the notion that The Lord of the Rings was inspired from World War II, Tolkien himself provided a "what if" scenario in the Foreword to The Fellowship of the Ring that shows what would happen should the Ring be used against Sauron. Tolkien explained that if he had WWII in mind, then the Free peoples would enslave Sauron with the power of the Ring against him, and occupy Mordor. Saruman (whose treachery would remain secret) would then use the Ring-lore found in Mordor to create a Great Ring of his own with which to challenge the self-styled Ruler of Middle-earth.[18]
