[4] The Delaware Nation's tribal complex is located two miles (3 km) north of Anadarko, Oklahoma on Highway 281.

The Oklahoma branches were established in 1867, with the purchase of land by Delaware from the Cherokee Nation; they made two payments totaling $438,000.

A court dispute followed over whether the sale included citizenship rights for the Delaware within the Cherokee Nation.

This was related to the colonial government's Walking Purchase of 1737, an agreement of doubtful legal veracity.

[9][10] The court held that the justness of the extinguishment of aboriginal title is nonjusticiable, including in the case of fraud.

In its conclusion the court stated: "... we find that the Delaware Nation's aboriginal rights to Tatamy's Place were extinguished in 1737 and that, later, fee title to the land was granted to Chief Tatamy—not to the tribe as a collectivity.
