The Mohave are of Yuman stock. They have lived for more than three
centuries in the bottomlands of the Colorado river where the present
states of California, Nevada, and Arizona adjoin. Down-stream to the
mouth of the Colorado were half a dozen kindred but often hostile
tribes, of whom the Yuma proper are the best known survivors. The
mountains to the east, in Arizona, were held by still other Yuman
groups—Yavapai, Walapai, Havasupai—of rather different habits from
the river tribes. To the north and east, the deserts of Nevada and
California were occupied by sparse groups of Shoshonean lineage.
The Mohave may have numbered 3000 in aboriginal times. In 1910 the
government counted 1058. Part of these had been transferred to a
reservation down-stream at Parker.
