This is a recent article I found explaining some elements of early european peoples. Specifically focusing on the caste system of priests, warriors, and producers. I found it very informative and suggest anybody else interested in history to read it too.

I fucking love trichotomies: Priest/Warrior/Producer, Religion/State/Economy, Communist/Fascist/Anarchist. They are just fun.

I've only read a couple parts of it so far, but it reminds me of Evola.

It’s an interesting read. I might end up doing a bit more reading on the subject. It’s been awhile since I spent any time studying the various histories and mythologies and I should probably pick them back up and delve a bit deeper into the subject.

I think it was more prevalent in the Indo-Aryan (India, Iran) branch than anywhere else. Most other Indo Erupeans did not have a warrior caste per se. The the warriors were mostly the same as the farmers in both the Norse and in Greece for instance.
