And I am also interested in the Middle Ages overall(from cultural, social, religious, etc. standpoints), the histories of Japan and other Middle East countries(as I have no idea about those, I would really appreciate some guidelines).

Since I am not a scholar, I would appreciate something accessible for a layman, but still, not overly simplified.

And if you have any other suggestions on periods, wars, etc. that are especially significant and present interesting and important ideas and concepts, I am looking forward to your suggestions.
