Tumulus culture
The early Bronze Age archeological cultures in France include the transitional Beaker culture (c. 2800–1900 BC), the Tumulus culture (c. 1600-1200 BC) and Urnfield culture (c. 1300-800 BC). Bronze Age sites in Brittany are believed to have grown out of Beaker roots, with some Wessex culture and Unetice culture influence. Some scholars think that the Urnfield culture represents an origin for the Celts as a distinct cultural branch of the Indo-European family (see Proto-Celtic). This culture was preeminent in central Europe during the late Bronze Age; the Urnfield period saw a dramatic increase in population in the region, probably due to innovations in technology and agricultural practices.
