The history of Western Europe in general opens with the struggle between Kelts, Romans, and Germans, which determined out of what elements modern nations should be formed.

Just as it is supposed that Albion in early times was connected with the Continent, and only separated from it by the raging sea-flood which buried the intermediate lands in the abyss, so in ethnographic relations it would seem as if the aboriginal Keltic tribes of the island had been only separated by some accident from those which occupied Gaul and the Netherlands. The Channel is no national boundary. We find Belgians in Britain, Britons in Eastern Gaul, and very many names of peoples common to both coasts; there were tribes which, though separated by the sea, yet acknowledged the same prince. Without being able to prove how far natives of the island took part in the expeditions of conquest, which pouring forth from Gaul inundated the countries on the Danube and Italy, Greece and Western Asia, we yet can trace the affinity of names and tribes as far as these expeditions extend. This island was the home of the religion that gave a certain unity to the populations, which, though closely akin, nevertheless contended with each other in ceaseless discord. It was that Druidic discipline which combined a priestly constitution with civil privileges, and with a very peculiar doctrine of a political and even moral purport. We might be tempted to suppose that the atrocity of human sacrifice was first introduced among them by the Punic race.
