Region of Oklahoma mentioned in  The American Claimant.  The character Washington Hawkins arrives in  Washington, D.C. as Congressional Delegate from Cherokee Strip.   "He explains to Colonel Sellers that he has no official status in Congress because 'we are not even a territory, there's no organic act,  the government hasn't any official knowledge of us whatever'."

The Cherokee Outlet, or Cherokee Strip, was located in what is now the state of Oklahoma in the United States. It was a sixty-mile (97 km) wide parcel of land south of the Oklahoma-Kansas border between the 96th and 100th meridians. The Cherokee Outlet was created in 1836. The United States forced the Cherokee Nation of Indians to cede to the United States all lands east of the Mississippi River in exchange for a reservation and an "outlet" in Indian Territory (later Oklahoma). At the time of its creation, the Cherokee Outlet was about 225 miles (360 km) long. The cities of Enid, Woodward, Ponca City, and Perry would later be founded within the boundaries of what had been the Cherokee Outlet.

The Cherokee Strip was a two-mile wide piece of land running along the northern border of much of the Cherokee Outlet. It was the result of a surveying error. The whole of the Cherokee Outlet is often called the Cherokee Strip.

In 1889, Congress authorized the Cherokee Commission to persuade the Cherokee to cede their complete title to the Cherokee Outlet. After a great amount of pressure, and confirmed by a treaty Congress approved March 17, 1893, the Cherokee agreed, for "the sum of $8,595,736.12, over and above all other sums" to turn title over to the United States government. On September 16, 1893, the eastern end of the Cherokee Outlet was settled in the Cherokee Strip land run, the largest land run in the United States and possibly the largest event of its kind in the history of the world.
