What was the last contiguous state admitted to the Union?
Idaho
New Mexico
Oklahoma
Arizona
Arizona was the 48th state and the last of the contiguous states to be admitted to the Union, achieving statehood on February 14, 1912. But the journey to statehood didn’t come easy. The region’s harsh climate, limited resources, and sparse population made it less attractive to settlers compared to other parts of the United States. As a result, Arizona spent 49 years petitioning for statehood until, finally, it was recognized as the 48th state of the Union on Valentine’s Day in 1912. Arizona was eventually followed by Alaska and Hawaii in 1959.
