About Oceanside, CA

Originally inhabited by Native Americans, the first European explorers arrived in 1769. Spanish missionaries under Father Junipero Serra founded Mission San Luis Rey de Francia on a former site of a Luiseño Indian village on the banks of the San Luis Rey River. In the early 19th century, the introduction of farming and grazing changed the landscape of what would become Oceanside. The area—like all of California—was under Spanish rule, then in 1821 under Mexican rule, and then the U.S. in 1848.
