California

California is a state on the West Coast of the United States, along the Pacific Ocean. It is the most populous U.S. state. Its four largest cities are Los Angeles, San Diego, San Jose, and San Francisco. It is known for its varied climate and geography as well as its diverse population.

The area known as Alta California was colonized by the Spanish Empire beginning in the late 18th century. It and the rest of Mexico became an independent republic in 1821. In 1846 California broke away from Mexico, and after the Mexican-American War, Mexico ceded California to the United States. It was admitted to the Union on September 9, 1850.
