The Druids were either an intellectual class or priestly class of Celts living in Gaul (a region that encompassed the majority of Western Europe and the British isles) around 1200-600 BCE and beyond. While modern neo-Druids have a tree-hugging, pagan, hippie vibe, the reality is that the original, historical Druids are sort of a mystery. Scholarly research and historical accounts suggest, though, that the Druids were more intellectual than they were religious, and that they spent more time establishing a socially just society than they did worshipping at places like Stonehenge, which, spoiler, wasn't even theirs. But what little we do know about Druid history and Druid beliefs is pretty fascinating.
