Answer: Because Over time, the east thrived, while the west declined. In fact, after the western part of the Roman Empire fell, the eastern half continued to exist as the Byzantine Empire for hundreds of years. ... The western half of the empire had a large trade deficit with the eastern half.Rome also benefited from modest levels of state formation in the western Mediterranean and the fact that larger kingdoms farther east were busy fighting each other. This allowed them to overpower and swallow other societies one by one.
