The traditional narratives of Native California are the folklore and mythology of the native people of California. For many historic nations of California, there is only a fragmentary record of their traditions. Spanish missions in California from the 18th century Christianized many of these traditions, and the remaining groups were mostly assimilated to US culture by the early 20th century. While there are sparse records from the 18th century, most material was collected during the 19th and the early 20th centuries.
Ethnolinguistically, most of the native peoples of California can be categorized into three large groups, Penutian, Hokan and Uto-Aztecan. Of these traditions, one of the best attested and most notable in US mainstream culture is Hopi mythology, the Hopi being a Pueblo people speaking a language of the Uto-Aztecan family.
A few versions of Native California traditional narratives were written down by Franciscan missionaries, notably Jerónimo Boscana in the early nineteenth century. Travelers, government agents, and local residents, such as Hugo Reid and Stephen Powers, added to this documentation in the later nineteenth century.
As anthropology in the United States transformed itself into a profession in the early twentieth century, preserving a record of native myths became one of its first major undertakings. Alfred L. Kroeber at the University of California, Berkeley, was a key instigator of these efforts, and the University's publication series, such as the University of California Publications in American Archaeology and Ethnology, as well as the Journal of American Folklore and other national journals, were important outlets for the results of the studies.
After the middle of the twentieth century, the work slowed somewhat. Much of the basic documentary work had been completed, and native cultural traditions had grown weaker with the passing of the decades. However, important contributions have continued to be made, especially in the presentation of narratives within their original languages as well as in translation.
