What difficulties might arise in governing such a large and divere empire???

Some difficulties that might arise when governing a league empire would be that your control over the empire would worsen. For example, in some areas the people may become out of control and try and create their own empire because they feel as though you won’t pay attention to them. Also, there is a greater sense of responsibility because their is likely more people in that country. To continue, other countries will want you to constantly be trading with them because of the large countries amount of resources!

Is there like something i’m supposed to cite because i don’t see any background information?
