The Californias - Statehoods

Statehoods

Two decades later, as a result of the Mexican–American War and the Treaty of Guadalupe-Hidalgo, Mexico permanently lost Alta California in 1848. The new areas acquired by the United States continued to be administered as territories, with the exception of California, which sprang into statehood a mere 2 years after annexation in 1850. But by the early 20th century all had become states. Mexico reorganized the Territory of Baja California into two territories in 1931, North Territory of Baja California and South Territory of Baja California. By the end of the 20th century each territory would become a state, Baja California in 1952 and Baja California Sur in 1974.
