The Oklahoma Organic Act of 1890 created an organized Oklahoma Territory of the United States, with the intent of combining the Oklahoma and Indian territories into a single State of Oklahoma. The citizens of Indian Territory tried, in 1905, to gain admission to the union as the [[State of Sequoyah]], but were rebuffed by [[United States Congress|Congress]] and an Administration which did not want two new Western states, Sequoyah and Oklahoma. [[Theodore Roosevelt]] then proposed a compromise that would join Indian Territory with Oklahoma Territory to form a single state.  This resulted in passage of the [[Oklahoma Enabling Act]], which President Roosevelt signed June 16, 1906.<ref>{{cite web | url=http://digital.library.okstate.edu/kappler/Vol3/HTML_files/SES0186.html#sec2a | title=Enabling Act (Oklahoma) Public Law 234, HR 12797, Jun 16, 1906 (59th Congress, Session 1, chapter 3335 | access-date=2012-01-30 | archive-url=https://web.archive.org/web/20160303170646/http://digital.library.okstate.edu/kappler/Vol3/HTML_files/SES0186.html#sec2a | archive-date=March 3, 2016 | url-status=dead }}</ref>  empowered the people residing in Indian Territory and Oklahoma Territory to elect delegates to a state constitutional convention and subsequently to be admitted to the union as a single state. Citizens then joined to seek admission of a single state to the Union. 

With Oklahoma statehood in November 1907, Indian Territory was effectively extinguished.  However, in 2020, the United States Supreme Court prompted a review of tribal lands through its decision in [[McGirt v. Oklahoma]].  Subsequently, almost the entire eastern half of Oklahoma was found to have remained [[Indian country]].
