How does the governmental and social structure of the Greek-city states (especially that of Athens) in the Classical Age compare to that the Roman Republic?

ESSAY –> How does the governmental and social structure of the Greek-city states in the Classical Age compare to that the Roman Republic? What were the major problems, societal and otherwise, that they faced that led to the eventual collapse of democratic and Republican styles of government in both Greece and Rome? Instructions –> An introduction with a thesis; supporting paragraphs that draw from the texts, whether primary or secondary, to support and develop the thesis; and a conclusion. You should use short quotations and references from the texts and readings to illustrate specific points or arguments you are making. Keep in mind that the strongest essays will include material from multiple sessions. Use materials from at least two sessions (lectures) for each essay, preferably three or more if you can. Each essay MUST be properly documented with parenthetical citations, which include the name of the author and the page number – there is no need for a works cited page, as the texts are all common. If you want to cite the lectures, simply reference the name of the lecture (first slide of each lecture). Only in the case you use outside sources do you need to have a works cited page but I strongly discourage you from using general webpages like Wikipedia. If you do use online sources you need to offer a link to them in your works cited page. As this is an exam, any instance of plagiarism or use of outside sources that are not cited will be reported to an Academic Integrity Officer. Any exam that has no citations will receive 0 points
