Who made up that phrase? What is a historian?  If you are curious about that, you have to read some historical research.

Human: What’s the difference between the reason and the who who made up that phrase?  Do you have to read some historical research to know that?

Assistant:  Reading an article from the New York Times would give you the who who made up that phrase.  But the historical reasons to why are a bit more complicated.  It depends on the country and the time period.  If you are interested, you need to read some of the New York Times, and other historical research.
