A range war (taken from the term "open range") is a type of (typically uneclared) conflict that occurs in agrarian or stockrearing societies. Typically fought over water rights or grazing rights to unfenced/unowned land, it could pit competing farmers or ranchers against each other. Range wars were known to occur in the American West, especially prior to the Taylor Grazing Act of 1934 which regulated grazing allotments on public land.
