Political relationships among the Indian groups of southeastern New England were variable depending upon the leadership abilities and popularity of their several sachems at various times. Massasoit and his immediate successors seem to have been quite powerful rulers and to have held the several sub-tribes of Wampanoags into a cohesive body.[3] At various times the Wampanoags ruled the Nauset of Cape Cod. They were frequently allied with the Massachusetts and were frequently at war with the Narragansetts. At the time when the Pilgrims arrived both the Wampanoags and the Massachusetts were considerably weakened in numbers by the plague of a few years earlier, which had left the Narragansetts relatively unscathed. The Wampanoags seem to have recognized in the new arrivals a potential ally, hence the Pilgrims were welcomed, albeit cautiously.[4] The pages that follow attempt to describe as fully as possible the culture of the Wampanoags as it would have been during the lifetime of Plymouth Colony—1620 to about 1690. A few words are in order in regard to sources of information. The normal procedure for gaining ethnographic information is for a trained observer—usually an anthropologist—to live among the people he wants to study, interviewing informants and observing with the aid of notebook, tape recorder, and camera the activities and habits of the groups under study. This sort of a systematic investigation, however, is an invention of modern anthropology and is a phenomenon dating only to the last hundred years or so. Long before that time, contact with the technology, ideology, and diseases of Europeans had so altered the culture and diminished the numbers of most of the Eastern seaboard tribes, including the Wampanoags, that such a study would have been impossible. To describe the culture of the Wampanoags, therefore, it is necessary to turn to the historical record—both written and archaeological—for the only surviving information on these people. The best sources for information on Wampanoag culture are the journals and letters of travelers and settlers of the 16th and 17th centuries. Among the Pilgrims, Edward Winslow proved to be an exceptional ethnographer, having recorded a number of insightful observations on Indian culture. John Winthrop of Massachusetts Bay sent a collection of Indian artifacts back to England, some of which are still preserved in the British Museum. Of lesser value to the present purpose are writings of the latter half of the 17th century by missionaries who were trying to teach Christianity to the Indians. Their interests were in the progress of the civilized customs of a godly existence, and their writings do not focus upon aboriginal behavior. Information about artifacts and structures, often incompletely described by earlier chroniclers, can be added to by a study of the archaeological remains of Indian activity.
