For instance, what is now the united Kingdom was occupied by tribes of hunters in the Neolithic, and then they joined with other people with different culture, who practiced the agriculture, the pottery among others (Stone Age). Then another people appeared with knowledge of working in bronze (Bronze Age). In the Iron Age other settlers arrived from the continent, for example the Celts, whose practiced the war.
With the last paragraph of people that settled that place, we could see how the natives and immigrants had different customs, beliefs, culture and so forth. For this reason, I think that it was a complex period of adapting of a new culture by the diversity of people and different way of life that they had in that area, now called United Kingdom.
