Folklore as a field of study further developed among 19th century European scholars who were contrasting tradition with the newly developing modernity. Its focus was the oral folklore of the rural peasant populations, which were considered as residue and survivals of the past that continued to exist within the lower strata of society. The "Kinder- und Hausmärchen" of the Brothers Grimm (first published 1812) is the best known but by no means only collection of verbal folklore of the European peasantry of that time. This interest in stories, sayings and songs continued throughout the 19th century and aligned the fledgling discipline of folkloristics with literature and mythology. By the turn into the 20th century the number and sophistication of folklore studies and folklorists had grown both in Europe and North America. Whereas European folklorists remained focused on the oral folklore of the homogenous peasant populations in their regions, the American folklorists, led by Franz Boas and Ruth Benedict, chose to consider Native American cultures in their research, and included the totality of their customs and beliefs as folklore. This distinction aligned American folkloristics with cultural anthropology and ethnology, using the same techniques of data collection in their field research. This divided alliance of folkloristics between the humanities in Europe and the social sciences in America offers a wealth of theoretical vantage points and research tools to the field of folkloristics as a whole, even as it continues to be a point of discussion within the field itself.
