Santa Fe (/ˌsæntə ˈfeɪ, ˈsæntə ˌfeɪ/ SAN-tə FAY, - fay; Spanish: [santa ˈfe]; Spanish for 'Holy Faith') is the capital city of the U.S. state of New Mexico. It is the fourth-most populous city in the state with a population of 87,505 as of the 2020 census, while the Santa Fe metropolitan area has an estimated 158,000 people. The greater Albuquerque–Santa Fe–Los Alamos combined statistical area includes eight counties in north-central New Mexico with 1.16 million residents. The county seat of Santa Fe County, Santa Fe is situated at the foothills of the Sangre de Cristo Mountains at the highest altitude of any U.S. state capital, with an elevation of 6,998 feet (2,133 m).
Founded in 1610 as the capital of Nuevo México, a province of New Spain, Santa Fe is the oldest state capital in the United States and the earliest European settlement west of the Mississippi River. Its name, Spanish for "Holy Faith", is the shortened form of its original name, La Villa Real de la Santa Fe de San Francisco de Asís (Royal Town of the Holy Faith of Saint Francis of Assisi). The city prospered as a leading commercial and transportation hub, driven by lucrative trade and migration routes such as El Camino Real de Tierra Adentro and the Santa Fe Trail. Nuevo México became a territory of Mexico after Mexican independence from Spain in 1821. It was ceded to the United States in 1848 following the Mexican–American War, and in 1851 Santa Fe was named the capital of the U.S. Territory of New Mexico; it became New Mexico's state capital in 1912. Santa Fe remained the political and cultural center of New Mexico throughout the Spanish, Mexican, and American periods, which each impacted the city's development and character.
