Who was the last state to join the United States before Oklahoma?

The last state to join the United States before Oklahoma was New Mexico. New Mexico became the 47th state on January 6, 1912, just a few months earlier than Oklahoma, which was admitted as the 46th state on November 16, 1907. New Mexico's admission helped to solidify the United States' territorial expansion in the southwestern region, greatly influencing the cultural and demographic landscape of the area. Understanding this context highlights the significance of New Mexico's statehood in the historical timeline leading up to Oklahoma's admission into the Union.
