The history of Moreno Valley is a tale of transformation from an arid valley to a thriving city, its development inextricably linked to water and military aviation. Long before the arrival of Europeans, these lands were inhabited by Shoshone Native American tribes. The first American settlers began developing the region after California became part of the USA in 1850.
Founding and Early Mentions
The city's modern history began in the 1880s when engineer Frank E. Brown developed a project to bring water from the San Bernardino Mountains to irrigate the land. This led to the founding of a farming community, which in 1887 was named Moreno, the Spanish word for "brown," in honor of the founder. However, prosperity was short-lived; in 1899, the settlement lost a legal dispute over water rights, leading to the desolation of the valley for many years.
Key Factors in Its Establishment
The region's revival began in 1918 with the opening of March Field (later March Air Force Base). This base became the primary economic engine and the largest employer, stimulating population growth throughout the 20th century. Particularly rapid growth occurred in the post-war years and the 1980s, when three separate communities—Moreno, Sunnymead, and Edgemont—began to merge into a single urban area. This process culminated on December 3, 1984, when the city of Moreno Valley was officially incorporated.
Early Cultural and Economic Characteristics
Initially, the region's economy was entirely agrarian, depending on agriculture made possible by artificial irrigation. After the decline of farming and the founding of the airbase, the economic and cultural landscape of the valley changed dramatically. Life centered around the military facility, attracting service members and their families from across the country. This formed the foundation for the future multicultural and dynamically developing city.
