As I understand it, The Æsir-Vanir War was a primordial conflict between two god races (The Æsir and Vanir) that ended with the two races becoming a unified pantheon.

I have recently learned that Norse Mythology is an example of Indo-European mythology and that the critical elements of the main stories can be refound all across the Indo-European religious landscape. My main takeaway from this knowledge is how ancient the roots of Norse Mythology are.

I have also recently learned of the Yamnaya culture and their migrations (invasions?) into the territories of the Funnelbeaker culture. The pastoralist Yamnaya and agricultural Funnelbeaker cultures merged into the Corded ware culture. DNA analysis of Corded ware DNA suggests marriages between Yamnaya men and Funnelbeaker women. Interestingly, only very little DNA from Funnelbeaker men made it into the Corded ware populations – indicating conflict or war.

Such a conflict and subsequent cultural merge must have left a vast impact on the people who experienced it, although the events are likely to have taken place over a long time. I imagine this impact would be reflected in the stories of the Corded ware people.

Given how old the roots of Norse mythology are, I feel it is natural to ask if the echoes of the Yamnaya/Funnelbeaker cultural clash or kiss are reflected in the stories of the Æsir-Vanir War. I find it particularly interesting that the Vanir gods who become Æsir are: Frigg, Freya, Frej, and Njord. Importing Freya into the Æsir pantheon could reflect the actual marriages between Yamnaya men and Funnelbeaker women, and Frigg is the wife of Odin. The Yamnaya were pastoralists from a steppe region, so I imagine they didn’t have gods for a good harvest (Frej) or the sea (Njord), so it seems likely they would have to import these from the other cultures when settling in an area where agriculture and the sea played a major role.

So my questions are:

1. Is it possible that the Æsir–Vanir War in Norse Mythology reflects the actual intrusions of Yamnaya people into the Funnelbeaker culture?
2. If yes, is it likely, and how can we falsify it?
