…in northern Europe.

I’m always amused by things like this:

Before the 1990s, “for a long time we didn’t really believe in war in prehistory,” DAI’s Hansen says. The grave goods were explained as prestige objects or symbols of power rather than actual weapons. “Most people thought ancient society was peaceful, and that Bronze Age males were concerned with trading and so on,” says Helle Vandkilde, an archaeologist at Aarhus University in Denmark. “Very few talked about warfare.”

Because they bought into Rousseau’s “noble savage” BS.

I suspect there’s still a lot more that we don’t know about human history than we do.
