Navajo Wars
The term Navajo Wars covers at least three distinct periods of conflict in the American West: the Navajo against the Spanish (late 16th century through 1821); the Navajo against the Mexican government (1821 through 1848); and the Navajo against the United States (after the 1847-48 Mexican-American War). These conflicts ranged from small-scale raiding to large expeditions mounted by governments into territory controlled by the Navajo. The Navajo Wars also encompass the widespread raiding that took place throughout the period; the Navajo raided other tribes and nearby settlements, who in return raided into Navajo territory, creating a cycle of raiding that perpetuated the conflict.
Spanish period
Facundo Melgares, the last Spanish governor of New Mexico before independence in 1821, conducted two unsuccessful expeditions against the Navajo,
who were attacking the New Mexican settlers. In October 1821 he sued for peace.
