History Chapter

I have a book I'm finishing. I have a chapter that is a very broad brush review of world history. It starts in Mesopotamia, Egypt, Indus Valley, Henan Valley, and goes through Greece, Rome, Europe, China, and culminates in the USA. It is 9,400 words. It is 23 pages. I need someone to review the chapter for historical accuracy and readability. This will be a part of my larger book that is on the principles of history titled "Foundation of Civilization". I've attached a portion of the chapter below.
