The fall of the Byzantine empire and the end of Rome were both caused by a combination of internal and external factors. Both empires were weakened by a series of wars, invasions, and economic decline. In both cases, the decline of the empire was hastened by the rise of powerful new empires, such as the Ottoman Empire in the case of the Byzantine Empire and the Germanic tribes in the case of Rome. In both cases, the fall of the empire led to a period of political and social upheaval.
