Covering vast swathes of Europe, the Bell Beaker Phenomenon has enjoyed a privileged status in the history of archaeology and is often referred to as a key period in the transition from the Neolithic to the Bronze Age partly due to the emergence of social élites. After a brief presentation of the historiography of the Bell Beaker phenomenon, this Element offers a synthetic account of the available evidence structured on a regional basis. Following the renewed interest in human mobility generated by stable isotopes and ancient DNA studies, the central thesis developed here is that the Bell Beaker Phenomenon can adequately be described as a metapopulation, a concept borrowed from population ecology.
