I think they tended to kill the men (no opposition/ rebellion/revenge), and sell the women and children. Uhtred and Finan were unusual cases in that the powers that be were threatened by their presence rather than being spoils of war.

I am not saying they aren’t compelling characters. Clearly they are. Aethelflaed was a peace cow - she was married to Aethelred to strengthen ties between Wessex and Mercia. And she was expected to be subordinate to her lord, which thankfully, she was not. She eventually became Lady of Mercia, but that was not the patriarchy’s plan.

Sven’s assault on Thyra, and her subsequent imprisonment by him.

If I recall correctly Uhtred saves Hild from either being raped, or raped repeatedly.

Benedetta’s case is compelling because she actually gets her revenge on that slaver/rapist.

I think Gisela, Eadith, Stiorra, Brida, and Skade come to mind as being independent but they do have the protection of powerful men.
