The Tataviam people had summer and winter settlements. They harvested Yucca whipplei and wa'at or juniper berries.
Traditional Language
Colonial scholars found themselves confused in their attempts to discern the language spoken by the Tataviam. Eventually it became clear to that errors had been made in compiling their word lists: the vocabularies recorded by colonial scholar C. Hart Merriam were not in fact Tatavian, but rather were from a Chumash dialect, while the vocabularies recorded by Alfred Kroeber and John P. Harrington were of the Uto-Aztecan language, meaning it is probably more likely that their recordings are the language spoken by the Tataviam people before they experienced genocide and language loss. Further research has shown that the Uto-Aztecan language belonged to the Takic branch of that language family, specifically the Serran branch along with Kitanemuk and Serrano. The last known Tataviam speaker died before 1916.
Neighboring Tribes
According to settler accounts, the Tataviam were called the Alliklik by their neighbors, the Chumash, probably because of the way their language sounds to Chumash ears.
Spanish Colonization
The Spanish first encountered the Tataviam during their 1769-1770 expeditions. According to Chester King and Thomas C. Blackburn, "By 1810, virtually all the Tataviam had been baptized at Mission San Fernando Rey de España." Like many other indigenous groups, they suffered high rates of fatalities from infectious diseases brought by the Spanish, as they had no immunity.
Following the Mexican Cession 1848, the ancestral land of the Tataviam people changed from Mexican rule to being part of the United States. The United StatesIndian Affairs decided to group the Tataviam with other Indian Villages in the same region, which is now Fort Tejon Indian Reservation.
During the California Genocide from 1846 to 1873, California’s Native American population plunged from perhaps 150,000 to 30,000. Many contemporary Tataviam people trace their lineage back to the original Tataviam people through genealogical records,, demonstrating the resilience of the Tataviam people in the face of genocide. In 1770, Alfred L. Kroeber estimated the combined population of the Serrano, Kitanemuk, and Tataviam to be 3,500 people. By 1910, their population was recorded at 150.
