Civilization and social inequality seem to go hand in hand, history homework help

Essay question

“Civilization and social inequality seem to go hand in hand. How have human societies attempted to develop ethical systems and thus regulate the abuses of power and violence, and ensure social harmony? In what ways have these attempts sown divisions among human beings. In your essay, please examine the formation of ethical systems between 500 and 700 BCE, the impact of universal religions between 100BCE and 600 CE, and the role of religion in the expansion of the Islamic Caliphate, European Christendom and the Mongol Empire.”

A tutor helped me in writing the essay that is attached with this question, when I read over it I realized a lot of information was missing (the bold part on the essay question above). I need those missing information. Please include the new info and edit any unnecessary details. I need the paper to stay 5 pages long.

Additional information and any changes to the essay needs to be highlighted so its easier for me to compare the new essay with the old one. Thank you.
