Liberal bullshit teaching. Blame it on whitey 
Seriously, even if that was invented by whitey, how can you not know that slavery existed well before 300-400 years? It is simply impossible to not know that... I mean that was even depicted in many hollywood movies or even Tv shows.
RANDOM example of slavery way more than 400 years ago:
Slavery in medieval Europe - Wikipedia, the free encyclopedia
How can a "history major" not know that? Unbelievable...
