In 1853,The U.S. Congress draft a bill creating the new territory but renaming it Washington Territory in honor of George Washington. The bill was known as the Organic Act and it was the basis for law in Washington until it became a state in 1889. At the time it was established, Washington Territory extended east to the Rocky Mountains, and included all of present-day Washington, western Idaho and western Montana.
