About San Diego County
San Diego County Timeline
San Diego County, located in Southern California, has a rich and diverse history that dates back thousands of years. The region was originally inhabited by Native American tribes such as the Kumeyaay, who lived off the land and established a vibrant culture.
In the 16th century, Spanish explorers arrived in the area, led by Juan Rodriguez Cabrillo, who sailed into San Diego Bay in 1542. However, it was not until 1769 that San Diego saw its first permanent European settlement with the establishment of Mission San Diego de Alcalá. The mission, along with others established by the Spanish, played a significant role in Hispanic colonization and Christianization of the native population.
San Diego County became part of Mexico after it gained independence from Spain in 1821. This era led to the development of ranchos, large land grants given to Mexican citizens, which significantly shaped the region's economy and society. However, in 1848, the Treaty of Guadalupe Hidalgo ended the Mexican-American War, and San Diego County became part of the United States.
The late 19th century brought significant changes to San Diego County, thanks in part to the arrival of the Santa Fe Railroad in 1885. This opened up new opportunities for trade and commerce, leading to a population boom and economic growth. Additionally, the discovery of gold in Julian in 1869 brought hundreds of fortune seekers to the area, further fueling development.
Today, San Diego County is a thriving metropolitan area with a diverse population and strong ties to its history. It remains a popular destination for tourism, known for its beautiful beaches, mild climate, and cultural attractions, while also being an important center for the military, technology, and biotechnology industries.
