Social structures, the domestic export and economies, and spiritual spheres within native Andean communities are key elements of analysis. Also highlighted is the persistence of duality in the Andean world: perceived dichotomies such as those between the coast and the highlands, Europeans and Indo-Peruvians. Even before the conquest, the Cabana and Collagua communities sharing the Colca Valley were divided according to kinship and location. The Incas, and then the Spanish, capitalized on these divisions, incorporating them into their state structure in order to administer the area more effectively, but Colca Valley peoples resisted total assimilation into either. Colca Valley communities have shown a remarkable tenacity in retaining their social, economic, and cultural practices while accommodating various assimilationist efforts over the centuries. Today's population maintains similarities with their ancestors of more than five hundred years ago--in language, agricultural practices, daily rituals, familial relationships, and practices of reciprocity. They also retain links to ecological phenomena, including the volcanoes from which they believe they emerged and continue to venerate.
