Didn't the Vikings enslave each other? What did they do with all the women they captured when they raided the other Viking villages?
Shhhh... If you burst my bubble, my ego will be hurt, my slef-esteem will deteriorate and I will, obviously, need the help a state appointed psychologist to help me out of my depression. After therapy I will actively seek to alter all the books you have ever read that could lead you to form such a gross mischaracterization of the loving, kind, gentle, tender and sweet Vikings that you have just disparaged. Now, repeat after me: Vikings enslave, they are not enslaved!
I think the Vikings tended to enslave people of the countries they raided.
