why did roman empire split into east and west
Western Roman Empire As the Roman Republic expanded, it reached a point where the central government in Rome could not effectively rule the distant provinces. Communications and transportation were especially problematic given the vast extent of the Empire. News of invasion, revolt, natural disasters, or epidemic outbreak was carried by ship or mounted postal service, often requiring much time to reach Rome and for Rome's orders to be realized in the province of origin. For this reason, provincial governors had de facto rule in the name of the Roman Republic.
