Slavery in Russian empire was de jure abolished about the same time as slavery in US. Not surprisingly, it took even more time for "de facto" changes to happen with various restrictions still being a thing into 1970ies. If anything, kolhoz system was anything but slavery with the government being ultimate owner.
