California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U.S., California is bordered by Oregon to the north, Nevada, to the east and northeast, Arizona to the southeast and it shares an international border with the Mexican state of Baja California to the south. The state capital is Sacramento. Los Angeles is California’s most populous city. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries. The Spanish Empire then claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its successful war for independence, but was ceded to the United States in 1848 after the Mexican–American War. The California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom.
If it were a country, California would be the 6th largest economy in the world. It is also regarded as a global trendsetter in both popular culture and politics, and is the origin of the film industry, the hippie counterculture, the Internet, and the personal computer, among others. Fifty-eight percent of the state’s economy is centered on finance, government, real estate services, technology, and professional, scientific and technical business services.
Although most of the state has a Mediterranean climate, due to the state’s large size, the climate ranges from subarctic to subtropical. The cool California Current offshore often creates summer fog near the coast. Farther inland, there are colder winters and hotter summers. The maritime moderation results in the shoreline summertime temperatures of Los Angeles and San Francisco being the coolest of all major metropolitan areas of the United States and uniquely cool compared to areas on the same latitude in the interior and on the east coast of the North American continent.
California is one of the richest and most diverse parts of the world, and includes some of the most endangered ecological communities. California is part of the Nearctic ecozone and spans a number of terrestrial ecoregions.
