The Pleasant Valley War
The Pleasant Valley War, sometimes called the Tonto Basin Feud, or Tonto Basin War, was commonly thought to be an Arizona sheep warbetween two feuding families, the cattle-herding Grahams and the sheep-herding Tewksburys. However, eyewitness reports show that sheep were not brought into Pleasant Valley until 1885, two years after the feuding between the Tewksbury and Graham factions began. Although Pleasant Valley is physically located in Gila County, Arizona, many of the events in the feud took place in Apache County, and in Navajo County. The feud itself lasted for about a decade, with its most deadly incidents between 1886 and 1887, with the last known killing occurring in 1892. Of all the feuds that have taken place throughout American history, the Pleasant Valley War was the most costly, resulting in an almost complete annihilation of the two families involved.
