After the fall of the Western Roman Empire, cities in Western Europe shrank dramatically and in some cases vanished altogether. In the Byzantine Empire, cities also shrank, although not to the extent that they had in Western Europe. In the Muslim world, however, cities did not shrink, and indeed, cities in the Middle East and North Africa prospered in what historians often refer to as a golden age of Islam.Why might cities have shrunk drastically in Western Europe, shrank somewhat in the Byzantine Empire, but prospered and grew in the Muslim caliphates? Your answer needs to be at least two paragraphs long and you need to respond to at least two other students’ posts. Remember to cite any outside sources!

Answer each question thoroughly. You MUST cite the readings throughout every answer. Part 1:Identify each term. You are explaining the nature and significance of abstract concepts, not providing “dictionary” definitions. Provide one paragraph for each definition.AnarchyCommunity (Lebow)Theory (use Waltz)SecurityPart Two: Succinctly but thoroughly answer each question. While you are not required to write a long essay for each question, your answers should leave no doubt that you absolutely understand the full scope of the relevant readings, as they pertain to question being asked.1. Drawing particularly on Gilpin and Lebow, assess the various ways that morality is addressed in realist thought. Be specific, and demonstrate understanding of the range of moral logics that these authors present. 2. Using the concepts of competition and socialization to anchor your analysis, explain what Waltz means when he writes that a structure “may designate a compensating device that works to produce a uniformity of outcomes despite the variety of inputs.”3. Compare how Waltz and Lakatos describe theory testing, DEFINING and explaining each of Lakatos's core terms in your own words. 4. Compare how Waltz and Mearsheimer explain why only the structure of the system matters for explaining state behavior, allowing us to ignore the internal characteristics of states.5. Three short questions, each worth 5 points: a) When Mearsheimer writes of defensive realists that they believe that the system will "punish" aggressors, what does that mean in real-world, specific terms? b) How does a hypothesis relate to a theory, and what role do hypotheses serve? c) Do realists think people can use their rationality to construct conditions that would make peace much more widespread than it is now? Explain. You must use the following textbooks. Cite them thoroughly throughout the answers.Robert O.
