Members of the Penutian-speaking family of languages, especially the Wintu, arrived in central Northern California in the vicinity of Redding, California about 1200 years ago, likely from southern Oregon. The Wintu possessed superior technology, were out-competing their Hokan-language family neighbors, and were expanding Wintu territory at the expense of the Okwanuchu and the Achomawi to the north, and the Yana to the east. It appears likely that even if Europeans and Americans not intervened (beginning in the 1820s), the Wintu would have absorbed or otherwise eliminated the Okwanuchu over the course of the coming centuries.
