History

The area was inhabited by the Kumeyaay people before contact with Juan Rodríguez Cabrillo in 1542 and the establishment of Mission San Diego de Alcalá by Gaspar de Portolá and Junípero Serra in 1769. The settlement became part of the Viceroyalty of New Spain, later the First Mexican Empire, and was ceded to the United States after the Mexican–American War via the Treaty of Guadalupe Hidalgo. During the 19th century, figures such as Alonzo Horton and events like the California Gold Rush and the arrival of the Southern Pacific Railroad shaped urban growth. Military installations including Naval Base San Diego, Marine Corps Recruit Depot San Diego, and Camp Pendleton expanded with the Spanish–American War and both World Wars, influencing population and industry. The 20th century saw the development of institutions such as University of California, San Diego and the rise of industries connected to Aerospace in California and biotechnology firms spun out of research at Scripps Institution of Oceanography and Salk Institute for Biological Studies.

The city occupies a coastal plain bounded by Pacific Ocean to the west, the Cuyamaca Mountains and Laguna Mountains to the east, and proximity to the Mexicali Valley. Neighborhoods and districts include Balboa Park, Old Town San Diego State Historic Park, La Jolla, Coronado, Point Loma, North Park, and Mission Bay Park. The climate is characterized as Mediterranean by the Köppen climate classification, moderated by the California Current and local marine layer, producing mild winters and warm summers; weather phenomena include June Gloom and occasional Santa Ana winds from the Inland Empire and Colorado Desert interior. Natural features include estuaries like San Diego River, coastal wetlands such as San Diego Bay, and protected areas like Torrey Pines State Natural Reserve and Mission Trails Regional Park.

Population growth was influenced by migration tied to World War II, the postwar boom, and immigration from Mexico.
