Las Cruces, also known as "The City of the Crosses", is the county seat of Doña Ana County, New Mexico, United States. The population was 97,618 in 2010 according to the 2010 Census, making it the second largest city in the state.
Las Cruces is the economic and geographic center of the fertile Mesilla Valley, which is the agricultural region on the flood plain of the Rio Grande which extends from Hatch, New Mexico to the west side of El Paso, Texas. Las Cruces is also the home of New Mexico State University (NMSU), New Mexico's only land grant university. The city's major employer is the federal government on nearby White Sands Test Facility and White Sands Missile Range. Recently the city has been home to many of the retired from across the country. The majestic Organ Mountains, ten miles (16 km) to the east, are dominant in the city's landscape, along with the Doña Ana Mountains, Robledo Mountains, and Picacho Peak.
The area where Las Cruces rose was previously inhabited by the Manso people, with the Mescalero Apache living nearby. The area was later colonized by the Spanish beginning in 1598, when Juan de Oñate claimed all territory north of the Rio Grande for New Spain and later became the first governor of the Spanish territory of New Mexico.
The area remained under New Spain’s control until September 28, 1821 when the first Mexican Empire claimed ownership. The area was also claimed by the Republic of Texas during this time until the end of the Mexican-American War in 1846–48. The Treaty of Guadalupe Hidalgo in 1848 established the United States as owner of this territory and Las Cruces was founded in 1849 when the US Army laid out the town plans.
Mesilla became the leading settlement of the area, with more than 2,000 residents in 1860, more than twice what Las Cruces had. When the Atchison, Topeka, and Santa Fe Railway reached the area, the landowners of Mesilla refused to sell it the rights-of-way, and instead residents of Las Cruces donated the rights-of-way and land for a depot in Las Cruces. The first train reached Las Cruces in 1881. Las Cruces was not affected as strongly by the train as some other villages, as it was not a terminus or a crossroads, but the population did grow to 2,300 in the 1880s. Las Cruces was incorporated as a town in 1907.
Growth of Las Cruces has been attributed to the university, government jobs and recent retirees. New Mexico State University was founded in 1888. And it has grown as Las Cruces has grown. The establishment of White Sands Missile Range in 1944 and White Sands Test Facility in 1963 has been integral to population growth. Las Cruces is the nearest city to each, and they provide Las Cruces' work force many high-paying, stable, government jobs. In recent years, the influx of retirees from out of state has also increased Las Cruces’ population.
In the 1960s Las Cruces undertook a large urban renewal project, intended to convert the old downtown into a modern city-center. As part of this, St. Genevieve's Catholic Church, built in 1859, was razed to make way for a Downtown Pedestrian Mall. The original covered walkways are now being removed in favor of a more traditional main street thoroughfare.
The origin of the city's name is unknown. In Spanish "Las Cruces" means "the crosses." (Some have claimed an alternative meaning of "the crossroads" but this is grammatically implausible, as "cruce", the singular form of crossroad, is masculine and the phrase would be "Los Cruces".)
