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 $4.1 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 2024 gross state product of $4.172 trillion as of Q4 2024. 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 (putting it, as of 2025, behind Germany and ahead of Japan) when ranked 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. Hollywood in Los Angeles is the center of the U.S. film industry and one of the oldest and largest film industries in the world; profoundly influencing global entertainment since the 1920s. The San Francisco Bay's Silicon Valley is the center of the global technology industry. (Full article...)

Panning for gold on the Mokelumne River
The California Gold Rush started in January 1848, when gold was discovered at Sutter's Mill. As news of the discovery spread, some 300,000 people came to California from the rest of the United States and abroad. These early gold-seekers, called "Forty-Niners," traveled to California by sailing ship and in covered wagons across the continent, often facing substantial hardship on the trip. Gold worth billions of today's dollars was recovered, leading to great wealth for some; others, however, returned home with little more than they started with. The effects of the Gold Rush were substantial. San Francisco grew from a tiny hamlet of tents to a boomtown, and roads, churches, schools and other towns were built. A system of laws and a government was created, leading to the admission of California as a state in 1850. New methods of transportation developed as steamships came into regular service and railroads were built. The business of agriculture, California's next major growth field, was started on a wide scale throughout the state. However, the Gold Rush also had negative effects: Native Americans were attacked and pushed off traditional lands, and gold mining caused environmental harm. (Full article...)

The Kern River is a river in the U.S. state of California, approximately 164 miles (264 km) long. It drains an area of the southern Sierra Nevada mountains northeast of Bakersfield. Fed by snowmelt near Mount Whitney, the river passes through scenic canyons in the mountains and is a popular destination for whitewater rafting and kayaking.
