Spanish land grants in New Mexico
The Spanish, and later the Mexican, government encouraged settlement of the Territorio de Nuevo Mexico (context map) by the establishment of large land grants, many of which were turned into ranchos, devoted to the raising of cattle and sheep. The owners of these ranchos patterned themselves after the landed gentry in Spain. Their workers included Native Americans, some of whom had learned to speak Spanish and ride horses. Of the hundreds of grants, Spain made only a few. The remainder were granted by Mexico after 1821. The ranchos established land-use patterns that are recognizable in the New Mexico of today.
Land grants were made both to individuals and communities during the Spanish (1598–1821) and Mexican (1821–1846) periods of New Mexico's history. Nearly all of the Spanish records of land grants that were made in what is now New Mexico prior to the Pueblo Revolt of 1680 were destroyed in the revolt. Thus, historians can often only be certain of land grants that were made after the Spanish Reconquest of New Mexico in 1693. "The two major types of land grants were private grants made to individuals, and communal grants made to groups of individuals for the purpose of establishing settlements. Communal land grants were also made to Pueblos for the lands they inhabited."
Spanish era 
During Spanish rule (1769–1821), land grants were typically concessions from the Spanish crown, permitting settlement and granting grazing rights on specific tracts of land, while retaining title with the crown. Ranchos, that is, the settlement by individuals of tracts of land outside Mission and Pueblo boundaries, began in the late 18th century. The land concessions were usually measured in leagues. A league of land would encompass a square that is one Spanish league on each side - approximately 4,428 acres (18 km2).
Notable land grants in New Mexico 
- Alameda Land Grant- Situated on the west bank of the Rio Grande and presently a part of Albuquerque and Rio Rancho, the Alameda Land Grant (also the Town of Alameda Grant) was a 89,000-acre (360 km2) parcel of land given by King Philip IV of Spain in 1710 to Francisco Montes Vigil, who later sold the land, which included only some farmland along the Rio Grande, to Captain Juan Gonzales of the Spanish Army. In 1929, 20,500 acres (83 km2) were purchased by Albert F. Black who established the Seven Bar Ranch. The Black family built an adobe home and in 1947 a small airport which was known as the "Alameda Airport". Surrounded by growing urban areas, the Black family sold off much of the remaining ranch for the development of new residential subdivisions. The Alameda Airport remained in operation until 1986, when it was closed to make way for 1983 plans for a 95-acre (380,000 m2) mall project.
- Atrisco Land Grant
- Elena Gallegos Land Grant-The Elena Gallegos Land Grant was created in 1694 for Diego Montoya, though settlers may have occupied it even earlier, prior to the Pueblo Revolt. In 1712 the grant, stretching from the crest of the Sandia Mountains to the Rio Grande, was reissued to Elena Gallegos. Her descendants further subdivided the approximately 70,000-acre (280 km2) plot such that when the land grant was re-adjudicated by American authorities in 1893 it was treated as a communal land grant. Much of northern Albuquerque is built on the former land grant. A large open space preserve is named for the grant.
- San Miguel del Vado Land Grant originally 350,000 acres in the Pecos River valley south of Pecos Pueblo. This land grant was a contributing factor in the demise of the Pecos Pueblo, which deteriorated from one of the leading pueblos to the point of the last families abandoning their land and moving to Jemez Pueblo. Overpopulation pressure and military protection centered at the San Miguel del Vado also contributed to the establishment of other land grants northeast of it, including the Las Vegas Land Grant.
