History
Members of the Tongva and Acjachemen nations long inhabited the area. The Tongva villages of Lupukngna, at least 3,000 years old, and the shared Tongva and Acjachemen village of Genga, at least 9,500 years old, were located in the area on the bluffs along the Santa Ana River. After the 1769 expedition of Gaspar de Portolà, a Spanish expedition led by Junípero Serra named the area Vallejo de Santa Ana (Valley of Saint Anne). On November 1, 1776, Mission San Juan Capistrano became the area's first permanent European settlement in Alta California, New Spain. In 1801, the Spanish Empire granted to Jose Antonio Yorba, which he named Rancho San Antonio. After the Mexican-American War, California became part of the United States, and American settlers arrived in this area and formed the town of Fairview in the 1880s near the modern intersection of Harbor Boulevard and Adams Avenue. To the south, meanwhile, the community of Harper had arisen on a siding of the Santa Ana and Newport Railway, named after a local rancher. This town prospered on its agricultural goods. On May 11, 1920, Harper changed its name to Costa Mesa, which means "coastal tableland" in Spanish. Costa Mesa surged in population during and after World War II, as many thousands trained at Santa Ana Army Air Base and returned after the war with their families. Within three decades of incorporation, the city's population had nearly quintupled.
