This dissertation analyzes two regional systems of involuntary servitude (Indian captive slavery and Mexican debt peonage) over a period spanning roughly two centuries. Following a chronological framework, it examines the development of captive slavery in the Southwest beginning in the early 1700s and lasting through the mid-1800s, by which time debt peonage emerged as a secondary form of coerced servitude that augmented Indian slavery in order to meet increasing demand for labor. While both peonage and captive slavery had an indelible impact on cultural and social systems in the Southwest, this dissertation places those two labor systems within the context of North American slavery and sectional agitation during the antebellum period. The existence of debt bondage and Indian captivity in New Mexico had a significant impact on America's judicial and political institutions during the Reconstruction era.

Debt peonage and Indian slavery had a lasting influence on American politics during the period 1846 to 1867, forcing lawmakers to acknowledge the fact that slavery existed in many forms. Following the Civil War, legislators realized that the Thirteenth Amendment did not cast a wide enough net, because peonage and captive slavery were represented as voluntary in nature and remained commonplace throughout New Mexico. When Congress passed a measure in 1867 explicitly outlawing peonage and captive slavery in New Mexico, they implicitly acknowledged the shortcomings of the Thirteenth Amendment. The preexistence of peonage and Indian slavery in the Southwest inculcated a broader understanding of involuntary labor in post-Civil War America and helped to expand political and judicial philosophy regarding free labor. These two systems played a crucial role in America's transition from free to unfree labor in the mid-1800s and contributed to the judicial and political frameworks that undermined slavery.

During the 1850s, Indian policy objectives pursued by the civil and military branches of government in New Mexico would have a lasting impact on future relations between the two cultures. Many later policies originated in this antebellum period, but often receive only a summary analysis by scholars who focus on the more popular post-Civil War period. Debates over proper policies and enforcement would proliferate in the 1850s as military and civil officials vied with one another over their own perceived authority. Many officials pursued viable policies, but did not remain in office long enough to ensure their implementation. Additionally, personal egos and stubbornness often undermined interagency cooperation. An overall cultural misunderstanding regarding Apache tribal structure and the inability to distinguish between subgroups exacerbated the conflict. Anti-Indian sentiments prevailed in the military, which often contradicted the more humanitarian approach advocated by the Indian Department. As a result, a contention for power and prestige emerged on three separate fronts: civil government leaders, military leaders, and within the Apache tribe. This thesis offers a contextualization of events that transpired during the 1870s and 1880s by demonstrating how these three entities contended amongst each other for power, undermining policy objectives in the antebellum era. Americans sought to conquer and control--to exert authority and power--over all components of the western landscape in order that they might realize its full economic potential. The Apaches formed a part of this landscape much the same as lofty mountain ranges, raging rivers, and parched deserts. All of these required conquering before that nineteenth century American dream could be fully imbued in the Southwest, and over the several decades following Kearny's arrival countless individuals streamed westward in torrents intent on accomplishing just that. The Apaches, like all western tribes, thus fell into an unstoppable cycle of conquest driven by an insatiable Anglo-American obsession with exerting control. Just as swarthy lawyers challenged claims to gain legal dominion over western tracts of land; just as engineers constructed dams and sought ways to manipulate streams and rivers; just as the plow tilled millions of acres of raw lands; just as the miner's pick slowly chipped away at formidable peaks; so too did the United States Army subdue the Apaches, all of these being a means towards a common end for the American West.
