Ever since contact, interest in the Comanches and Hasinais has been continuous. Spanish diplomats, missionaries, traders, and military sources collected information about these two communities’ political organizations, demographics, religious beliefs, subsistence, and locations. Using the same methods for gathering intelligence, early American and French forays into the region continued to gather data regarding the internal organizations of the Comanches and Hasinais. Not until the development of anthropology as a discipline, however, did this past information as well as newly learned data concerning these populations become more systematized.
