This dissertation examines incidents of conflict and violence amid communities of the Maya Tzotzil Chamula in Chiapas, Mexico. Despite ostensible homogeneity, or more social and cultural resemblances than differences, conflicts arise between many Chamula because of how they acquire desire according to others who mediate what is desirable. These conflicts relate well to Rene Girard's hypothesis that mimetic desire influences identity yet generates conflict as imitation fosters rivalry. Qualitative methods of participant observation, interviews, and document research depict how desire, identity, and conflict interrelate. Ethnographic cases show how conflict emerges "interdividually" as rivals compete to obtain objects imputed desirable. The study begins with how young Tzotzils today appropriate the desires of others, becoming lawyer, spiritual guide, rock and roll singer, or anthropologist. Complex examples exhibit groups struggling for power and privilege within or between members of communities as they vie over "objects of desire" such as status, land, water, or representations of power and pecuniary interests. For some Chamula, mimetic rivalry works to deny resemblances with others despite being alike as neighbor, relative, farmer, carpenter, or member of the same political or religious affiliation. The study also highlights mimetic interactions that have shaped Maya struggles in the past, such as the uprisings of 1712, 1867, and 1911. Interpretive analysis explores how identity formation (structures), imitative desire (motivated interaction), and practice (habitual agency) together galvanize material and psychosocial variables for conflict. Imitative desire is worth observing because of its long-term implications for human adaptation and social change. As a contribution to social conflict theory, this dissertation offers a critical perspective to current research on mimetic desire as a significant force in human relations.
