Idaho is the only state that was possibly named as the result of a hoax (the so-called "Idahoax") although this is disputed. In the early 1860s, when the United States Congress was considering organizing a new territory in the Rocky Mountains, eccentric lobbyist George M. Willing suggested the name "Idaho," which he claimed was derived from a Shoshone language term meaning "the sun comes from the mountains" or "gem of the mountains." Willing later claimed that he had made up the name himself. Congress ultimately decided to name the area Colorado Territory when it was created in February 1861.
