Klickitat people
In the early 1850s, the Klickitat Tribe raided present-day Jackson County, Oregon from the north and settled the area. Modoc, Shasta, Takelma, Latgawas, and Umpqua Indian tribes had already lived within the present boundaries of that county.
Klickitat people
Between 1820 and 1830, an epidemic of fever struck the tribes of the Willamette Valley. The Klickitat took advantage of the drop in population in this region and crossed the Columbia River and occupied territory occupied by the Umpqua. This was not permanent, however, as they were pushed back to their original homeland.
