The area encompassing Fountain Valley was originally inhabited by the Tongva people. European settlement of the area began when Manuel Nieto was granted the land for Rancho Los Nietos, which encompassed over 300,000 acres (1,200 km2), including present-day Fountain Valley. Control of the land was subsequently transferred to Mexico upon independence from Spain, and then to the United States as part of the Treaty of Guadalupe Hidalgo.
