The word for "slave" in all the major European languages (I think) comes from the word for "Slav."
Slavic people have a very different approach to their ancestral role as slaves than do African Americans. I'm unaware of any demand for reparations or even pity. In fact I've never heard a Slavic person broach the topic of their ancestors' enslavement. I've never heard a Slavic person express any hostility whatsoever towards Scandinavians, Jews, or Muslims, for their role in the enslavement of Slavic people. It just never comes up.

Silver coins found previously in the area have mostly been Arab dirhams, used by Muslim merchants to pay for human chattel.
