Hey there! Sorry to disappoint you with the little orange envelope, but I'm not a historian and I have no idea how to answer your question.

However, what I can tell you is that you've made a pretty common mistake - you're ostensibly asking about the entire world for a period of like a thousand years, and things change a lot across time and distance. You might get the attention of more historians if you narrowed your scope, even if you just gave a century and something like 'western Europe'.
