Alliances were not fixed
Relationships between Apache groups and their neighbors were not permanent friendships or permanent hostilities. They changed with the generation, the season, the group and the wider pressures of the time, including the arrival of Spanish, Mexican and American power. Because “Apache” covers several distinct nations, a statement about one group often does not hold for another. A Jicarilla family trading in a northern New Mexico village had a different set of neighbors from a Western Apache band in central Arizona or a Lipan community in Texas.
Pueblo peoples
Contact between Apachean groups and Pueblo communities along the Rio Grande and elsewhere is documented over a long period. The most commonly described relationship was exchange: Plains-oriented groups brought bison products such as meat and hides, and Pueblo communities supplied agricultural goods such as corn, along with other items. The trade fairs held at places such as Taos are often cited in this context, and the Jicarilla and Pueblo trade is a well-known example. Intermarriage and visiting also occurred in some places.
The same relationships were not always peaceful. Raiding and counter-raiding between Apachean groups and Pueblo or Spanish settlements is recorded in colonial documents, and sources differ about how to read the balance of trade and conflict. During the Spanish colonial era, some Pueblo communities and Apache groups found themselves on opposite sides of Spanish policy, and at other times on the same side of it.
Navajo
The Navajo are close linguistic and cultural relatives of the Apache peoples, both belonging to the Southern Athabaskan (Apachean) language family, yet the idea of Navajo as separate nation is important: they are a distinct people, now organized as the Navajo Nation. Historical records describe periods of cooperation, intermarriage and trade between Navajo and some Apache groups, and periods of raiding and hostility. Neither “kin” nor “enemy” is a complete description, and it varied by local group and decade.
Comanche
Comanche expansion onto the southern Plains in the 1700s changed the map for several Apache groups. The Lipan Apache and other Plains-oriented Apachean peoples are generally described as being pushed southward over time, partly by Comanche pressure, though the details are debated. The picture of Apache relations with Comanche is not one of constant fighting, however. There were also periods of truce and trade, and Comanche groups later appear in some accounts as trading partners or as common players in treaties with Spain and Mexico. By the nineteenth century, the Comanche were one of the dominant powers on the southern Plains, and Apache groups in that region adjusted accordingly.
Kiowa and the Plains Apache
The Plains Apache are the clearest case of a long alliance. They became closely associated with the Kiowa, to the point that outsiders adopted the Kiowa Apache name, which reflects that association. Their historical ties with the Kiowa, and through the Kiowa with other Plains peoples, are well documented, and today they are recognized as the Apache Tribe of Oklahoma. They are an Apachean people with their own language, and the name Kiowa Apache is considered by many to be an imprecise outsider label.
Other relationships
Other relationships are also recorded, such as those with the Yavapai in Arizona, with the Hopi and Zuni in some periods, and with O’odham neighbors to the south. The nature of these varied from trade and intermarriage to rivalry. Apache and Spanish relations, and later relations with Mexico and the United States, were a separate matter, shaped around the Spanish presidio frontier and its garrisons, often involving agreements that were made and then broken, and are treated in other articles on Spanish and American relations.
Why alliances formed
The sources suggest several reasons for forming ties: access to trade goods, security in a landscape where resources were unevenly spread, kinship through marriage, and shared interest against a common rival. Alliances were usually maintained through repeated contact, gifts and marriage, and could weaken when a key relationship ended or when external pressures changed the incentives.
Reading the evidence
Information about these alliances comes from Spanish and Mexican reports, American military and agency records, ethnographies and Indigenous oral traditions. Colonial writers often described Apache groups from the viewpoint of conflict, so peaceful exchange can be underrepresented. Readers interested in how these sources are weighed can look at the discussion of oral and written evidence elsewhere on this site.
