By the turn into the 20th century, European folklorists remained focused on the oral folklore of the homogeneous peasant populations in their regions, while the American folklorists, led by Franz Boas, chose to consider Native American cultures in their research, and included the totality of their customs and beliefs as folklore. This distinction aligned American folklore studies with cultural anthropology and ethnology, using the same techniques of data collection in their field research. This divided alliance of folklore studies between the humanities and the social sciences offers a wealth of theoretical vantage points and research tools to the field of folklore studies as a whole, even as it continues to be a point of discussion within the field itself.[12]
