2000–1500 BC
Invasion by a bronze-weaponed, broad-headed, beaker-making, avenue-building people from Spain by way of Southern France and the Rhine. Further immigration of long-heads from the Baltic, and from South-Eastern Europe by way of the Rhine. Cremation and the less ostentatious though better furnished round barrows were introduced. The leaf-shaped arrow-heads persisted, as they did in burials in France until early Imperial times; but the characteristic type was barbed and tanged in the shape of a fir-tree.
