Just 150 years ago Russia formally abolished slavery. Slaves in Russia were called “krepostnye” or “fixed” – the ones that couldn’t do anything with their lives without their master’s OK. They couldn’t move away, couldn’t marry, couldn’t change who they worked for. They were often beaten and were more or less property. They could be bought and sold for cash or gold. Just like African slaves in USA, except they were local Russian white skinned people.
So how much money did you need 150 years ago to buy a Russian man, woman or a kid?
