the only evidence that they practiced human sacrifice is Roman propaganda designed to show that the Celts and Gauls were uncivilised barbarians who needed to be conquered.
Unfortunately, that's pretty much the only evidence full stop! As Urlik says, it
might be wrong, but there is precious little to substantiate the opposing view.
the Druids were the priest class of Celtic polytheism, but as they used an oral tradition for passing on their knowledge and there is no written record of their practices, there is absolutely nothing really known about them except that they revered the Moon, the oak, mistletoe and white bulls
From which tiny clues a whole pseudo-religion has sprung, fully formed like warriors from dragon's teeth!
But by the later Celtic period, most of the Celts were at least nominally Christian.
I realize that overall they are Celts and therefore primarily warlike, but I believe that they resort to war only when necessary and the rest of their society is rather peaceful and long lasting.
As MTF suggests, there is not a shred of evidence to support this view. It's a fashionable view, I grant you, but what evidence there really is paints the Celts (like the Saxons) as first and foremost a warrior aristocracy who (like the Saxons) effectively took over the upper strata of British society. In "Gallic Wars", old Julius Caesar states that one of their principle exports was slaves - hardly the mark of a peaceful society.
I concede that the Bretons were warlike during the post-Roman era. They had to be after the chaos of the Roman structure leaving and then defending against several nations and dozens of tribes all wanting the island.
But let us look at these "dozens of tribes". Some were Germanic - Saxons, Angles, Jutes et al, but the pressing threat of the post Roman period came from the Picts (who were Celts) and the Irish (who were Celts). So, once again, not much evidence of the Celts being peace-loving there!
Their biggest mistake is inviting the Saxons to help defend them thereby inviting their soon to be conquerors.
In all fairness, Vortigern was just following accepted late Roman military practice of paying one lot of thugs to defeat another, but even if not, what choice did he have? For whatever reason, it appears that the North did not come and help him and there is evidence (in the form of Coel Hen), that the British still held enough power at York and along the Wall to keep effective control of what is now northern England and Southern Scotland for nearly 200 years after the Saxon rebellion.
If the Bretons could have held off the invaders on their own and united and organized under something similar to what they had during the Roman occupation, they would probably have been fine for the next few centuries.
I agree. This is the real nub of the problem. The Saxons didn't win Britain - the Celts threw it away. They couldn't (or wouldn't) unite behind one leader.
I think in the end all of you Brits are just gonna have to face it; its not natural to live on that cold wet island of yours
Too true. We'd all much rather live in Disneyland or exotic places with names like Big Flat Desert, Kansas, or Hot Burrito, Oklahoma.
