Yes they were, but for short period of WW2, millions of people were enslaved by Germans, and it was absolutely systemic and racist, they were enslaved on a basis of being Slavs and Jews.
Also the serfdom could be called slavery with no problem, in some places peasants were literally traded like chattel. This was not racist though, enslavers were in this case mostly members of the same ethnicity.
