On July 3, 1890, Idaho was admitted to the Union as the 43rd state. The territory had grown through mining, ranching, and agriculture in the decades after initial settlement. Statehood recognition reflected the region’s increasing population and economic importance. Idaho’s admission strengthened U.S. political presence in the interior West. It also formalized relationships between federal authorities and local governments. The new state would later become known for its natural resources, including forests, minerals, and farmland.
