Macro environmental shift of baghdad under the abbasids

I need you to go over my entire dissertation and change it, so it makes more sense and is more in line with my topic of discussion. I will attach my dissertation abstract which has all of the instructions on what you need to do , I will also attach my literature review (please read it as it is a good starting point to get an idea of what I want)
