“A Germanic tribe, the Druids, were mainly responsible for its introduction into Christmas lore.”

Was it over when the Germans bombed Pearl Harbor?

Hint: there was no “Germanic tribe” called the Druids.

[Vigilanteman]

Technically correct. It is also technically incorrect to describe the Druids as a tribe at all. It was more like a religion with the strongest influence on the tribes of Gaul (according to ancient Greek texts) or the Celtic tribes (according to ancient Roman texts), but the range of influence included Germanic tribes as well some of whom migrated to the British isles, notably the Saxons.

Christianity, of course, reached what is now Germany before it reached what is now the British Isles and the Christmas tree is a legacy of these Germanic tribes. So, for that matter, is the English language part of the Germanic language family.

Still, I concede your win on said technicality. Happy now?
