Article: There is a large body of evidence for fortified settlements at Linearbandkeramik sites along the Rhine, as at least some villages were fortified for some time with a palisade and an outer ditch. Settlements with palisades and weapon-traumatized bones have been discovered, such as at the Talheim Death Pit demonstrates "...systematic violence between groups" and warfare was probably much more common during the Neolithic than in the preceding Paleolithic period. This supplanted an earlier view of the Linear Pottery Culture as living a "peaceful, unfortified lifestyle".
