The brown areas show where the beaker culture was
The Bell-Beaker culture (or Beaker culture, Beaker people or Beaker folk) is the name of a cultural phenomenon which occurred in large parts of Western Europe, roughly between 2800 BC and 2200 BC (in Great Britain until about 1900 BC). Today, it is unclear whether this can be seen as a culture.
Paul Reinecke was the first to use the word Glockenbecher (bell-shaped cup) in German, around 1900. Other historians from Italy and Czechoslovakia had used similar terms before.
