During World War II, California was home to several important military installations, including Naval Station Pearl Harbor and the Los Alamos National Laboratory. The state's aircraft manufacturing industry also played a crucial role in the war effort.
San Mateo County, located in Northern California, has a rich history dating back thousands of years. The area was originally inhabited by various indigenous tribes, including the Ohlone people, who lived off the land and coastline. European exploration began in the late 18th century, with Spanish explorers and missionaries venturing into the region.

In the early 19th century, the Mexican government granted large land grants, known as ranchos, to influential individuals. Rancho San Mateo was one of these grants, encompassing much of what is now San Mateo County. The California Gold Rush in the mid-1800s brought an influx of settlers to the region, leading to the development of towns and a growing economy.

The completion of the Central Pacific Railroad in the late 19th century boosted the county's growth, providing easier access for trade and transportation. With the railroad's arrival, cities like Redwood City and San Mateo saw rapid development and urbanization, attracting more people to the area.

In the 20th century, San Mateo County experienced further growth with the rise of technology and industry. Companies like Oracle and Electronic Arts chose to establish their headquarters within the county, contributing to the region's reputation as a tech hub. Today, San Mateo County remains a vibrant and diverse community with a strong economy, beautiful coastline, and a blend of rural and urban areas.
