What year did Arizona achieve statehood?

Arizona achieved statehood in 1912, becoming the 48th state to join the United States. This was a significant milestone after a long process that began with the region's acquisition through the Treaty of Guadalupe Hidalgo in 1848 and the subsequent establishment of Arizona as a U.S. territory in 1863. The journey to statehood involved overcoming various political and social hurdles, including debates around governance, economic viability, and the integration of diverse communities.

The date of 1912 is not only important because it signifies Arizona's entry into the union but also reflects a period of growth and development for the state, as it transitioned from a territory characterized by mining and ranching economies to a more diversified state. The year distinguishes Arizona as one of the last contiguous states to be admitted, affecting its political landscape and its representation in Congress.
