Neolithic farmers arrive, bringing Ireland's first cattle, sheep, goats, wheat and barley. For thousands of years the diet of people in Ireland will mainly comprise meat and dairy products, since the Irish climate lends itself to semi-nomadic pastoral farming. To build Newgrange would have taken 400 people, working for the summer months, at least 16 years.

They introduce the horse and flax to Ireland. According to the seventeenth-century Annals of the Four Masters, Tighearmas, king of Ireland, is the first person to dye clothes blue, purple and green.

They have a strong belief in an afterlife, hence no fear of dying in battle. Irish Celts raid Roman Britain.
