California was admitted as the 31st U.S. state on September 9, 1850, as part of the Compromise of 1850, becoming a free state.
The admission occurred following the Treaty of Guadalupe Hidalgo, which ceded California to the United States in 1848. The Compromise of 1850 included provisions approving California's entry as a free state. This legislative package aimed to defuse tensions between slave and free states, with the admission date becoming a state holiday.
