What year did Oklahoma legalize statehood?

Oklahoma was officially granted statehood on November 16, 1907. This event marked the culmination of a long process that began with the opening of the Oklahoma Territory to settlers in 1889. Efforts to create a state government and constitution eventually led to Oklahoma being admitted as the 46th state of the United States. The 1907 statehood was significant as it represented a merging of the Oklahoma Territory and the Indian Territory, which had existed as separate entities prior to statehood. This historical development was driven by political and social pressures, including the desire for local governance and the integration of diverse populations within the area.
