Ishi's mother was left unharmed, but died soon after. Two of the Native Americans fled, and were never heard of again. A tiny settlement inhabited by Ishi, his elderly mother, and two others was found by some surveyors in 1908, who then looted the village. The number of Yahi living near their ancestral home shrank rapidly, and in 1872 they were believed to have gone extinct. Most of the Yahi were killed by settler militia in the early 1800s. The Yahi lived near the foothills of Mount Lassen for several thousand years before the arrival of white settlers. Ishi, believed to have been born between 18, was a member of the Yahi people, a subgroup of the Yana, a Native American tribe.

The book was twice adapted into film, in 1978 (as Ishi: The Last of His Tribe) and 1992 (as The Last of His Tribe). It sold widely, remained in print for many years, and was translated into more than a dozen languages.
