Description & Facts: Prior to European settlement in the area, the peninsula that now contains San Francisco was home to the Yelamu tribe, who were part of the larger Ohlone language group which stretched south from the Bay Area to the Big Sur of California. Due to San Francisco's characteristic foggy weather, the earliest European explorers completely bypassed the Golden Gate and the San Francisco Bay. The first European settlement in the area was founded by the Spaniards in 1776 as a mission community surrounding the Mission San Francisco de As??s, in what is today called the Mission Dolores in the Mission District. In addition to the mission, a military fort was built near the Golden Gate: the Presidio. Upon gaining independence from Spain in 1821, the area became part of Mexico. Under Mexican rule, the mission system gradually came to an end and private ownership of land became a possibility. In 1835, an Englishman named William Richardson founded the town of Yerba Buena, the first significant settlement on the peninsula outside of the Mission Dolores area. As the new settlement gradually grew, Yerba Buena developed a street plan and became attractive to settlers. In 1846, the United States claimed California, and in July of that year, the U.S. Navy arrived to raise the American flag above Yerba Buena. Over the next couple of years, California officially became part of the United States following the Mexican-American War, and the name of the town was changed from Yerba Buena to San Francisco. With the California Gold Rush of 1848, San Francisco began to explode in population. Waves of immigrants came to the city to seek their fortunes, including large numbers of Chinese immigrants, forming one of the largest Chinese populations outside of Asia. During this time, many major businesses were created and flourished in San Francisco, and famous (and infamous) personalities settled in the city. Of course, with all this success came problems: the rapid growth of the city outstripped any efforts at city planning, meaning proper sanitation and infrastructure were largely undeveloped, which led to a cholera outbreak in 1855. Violence and corruption were evident, and anti-immigrant violence resulted in many race riots. For a good book on the tumultuous early history of San Francisco, read Herbert Asbury's Barbary Coast. In the 1890's, there was a large campaign to modernize and beautify the city, the success of which led some officials to proudly call San Francisco the "Paris of the West." But in 1906, a devastating earthquake shook the city and a resulting fire leveled much of the city (in fact, almost 90% of the total damage was from the fire, and not the quake itself). Nevertheless, officials at the time immediately set out on a plan to rebuild the city, with new parks, boulevards, the current civic center complex, and landmarks such as the Coit Tower atop Telegraph Hill. In 1915, San Francisco hosted the Panama-Pacific Exposition (where the Palace of Fine Arts complex is currently located) to showcase the completely rebuilt city. In the wake of the Great Depression of the 1930's, San Francisco remained largely unscathed. In fact, it was during this time that the Golden Gate Bridge and the Bay Bridge were conceived and built. It was also during this time that the Federal Government established a prison on Alcatraz Island, which would hold some of the most notorious criminals of the era. After World War II, San Francisco continued to grow in population. Urban planning projects at the time led to more highrises downtown (including the Transamerica Pyramid) and the destruction of many neighborhoods to build freeways (many of which were later torn down after the 1989 Loma Prieta earthquake). In the same period, San Francisco became a center of counterculture and the hippie movement, contributing to San Francisco's liberal outlook. San Francisco also became a center for homosexuals during this time, leading to the development of gay neighborhoods like the Castro. More recently, San Francisco has experienced a boom in business.
