There seems to be a growing phenomenon, ever since the mid-20th century, to create a more positive outlook towards the barbarian tribes of Europe. One good example of this is Terry Jones' Barbarians. Celtic revivalism is certainly gaining ground in Britain and in France, resulting in the reconstruction of some Celtic cities even, and highlighting the more egalitarian, "free" societies of the Celts. Many Slavic countries in Eastern Europe have a superficially similar though fundamentally different revival of "pagan" pasts, where Russians begin to highlight their Viking past more, and Slavs in general have a greater appreciation of Pagan Slavic gods like Perun.
To what extent are such movements good? Are were restoring the balance in history or are we going towards an extreme and distorting history to paint the natives in a better light? I am not even talking about "noble savage" concepts, but rather the belief that the Celts or the Thracians had produced admirable civilizations.
I think we need to consider several things before drawing a conclusion:
1) Our perception of ancient Europe is terribly biased by Greek and Roman authors. Terry Jones even went so far as to say that the only thing which made Celtic towns "hill-forts" was the fact that the Romans described them as such; surely we would say Roman cities were "hill-forts" (let's not forget Rome was founded on 7 hills) had the Celts won. Our impression of Celts and other barbarians as violent savages comes from Roman writers, commenting on societies that they neither understood, nor cared to understand since they considered Rome superior to all. In common perception this has even affected the "admitted civilizations" in the East. The Persians are ironically depicted as imperialist slave-drivers while the Hellenes become the defenders of the free world and democracy. The sacking of Athens is pretty well-known but Alexander the Great's exploits, no less violent, are depicted in a brighter light. For the Romans this is even more exaggerated, as I will show in what follows.
2) Roman presence in an area often diminished the standard of living and destroyed more cultural achievements than we can name. Celtic civlization was badly bludgeoned, while Dacian civilization was systematically and almost completely dismantled. The Romans destroyed many centers of innovation in the Hellenic world. Who knows how many inventors shared the fate of Archimedes, dying by the sword of legionnaires?
3) Our perception of barbarians as being materially poor and lacking culture comes from the fact that the Romans destroyed those civilizations. The archaeological findings so far from both the Celtic and Balkan world prove that "barbarians" were neither technologically inferior to Romans, nor did they lack the means of production that the Romans employed. In some areas the Romans were even surpassed by their enemies, and the Romans adopted even military innovations from the barbarian world (chainmail, the gladius, dracone standards, armored horses).
So what is your opinion on this trend? Is this trend a return to normality and to objective history, cleaning up historiographies that still bear the taint of Gibbon, or is it just nationalist revisionism with little basis in actual history?
