California Statehood

California became the 31st state of the United States on September 9, 1850, as part of the Compromise of 1850, which aimed to balance free and slave states. The discovery of gold in 1848 spurred a rapid population increase, leading to the area seeking statehood. Prior to joining the U.S., California was part of Mexico. Its admission helped expand U.S. territory westward and contributed to economic growth. California's statehood marked a significant moment in American history, reflecting its transition from a sparsely populated region to a vital, diverse state with a major influence on the nation.
