California (/ˌkælɪˈfɔːrniə/) is a state in the Western United States that lies on the Pacific Coast. It borders Oregon to the north, Nevada and Arizona to the east, and shares an international border with the Mexican state of Baja California to the south. With almost 40 million residents across an area of 163,696 square miles (423,970 km2), it is the largest state by population, third-largest state by area and the largest state economy in the U.S., with a GDP of approximately $4.3 trillion.

Prior to European colonization, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America. European exploration in the 16th and 17th centuries led to the colonization by the Spanish Empire. The area became a part of Mexico in 1821, as a result of its successful war for independence. Following the U.S. conquest of California, part of the Mexican-American War, California was ceded to the United States in 1848. The California gold rush started in 1848 and led to social and demographic changes, including the California genocide. It organized itself and was admitted as the 31st state in 1850 as a free state, following the Compromise of 1850.

The economy of California is the largest of any U.S. state, with an estimated 2025 gross state product of $4.296 trillion as of Q3 2025. It is the world's largest sub-national economy and, if it were an independent country, would be the fourth-largest economy in the world (behind Germany and ahead of Japan, as of 2025) by nominal GDP. The state's agricultural industry leads the nation in output, fueled by its production of dairy, almonds, and grapes. With the busiest port in the country (Los Angeles), California plays a pivotal role in the global supply chain, hauling in about 40% of goods imported to the US. Notable contributions to popular culture, ranging from entertainment, sports, music, and fashion, have their origins in California. Despite an exodus of filmmaking from California, Hollywood continues to be an important center of the U.S. film industry, one of the oldest and largest film industries in the world; profoundly influencing global entertainment since the 1920s. The San Francisco Bay Area's Silicon Valley is the center of the global technology industry. (Full article...)
