How did life change between the Roman Empire and the Middle Ages?

It went from an organized society with a Roman government and services to chaos in 410 AD when Rome fell. In the early middle ages Vikings were invading and there was constant war. By the time of the high middle ages society and nobility was getting stronger and the church was taking control. William the Conqueror became king and the Magna Carta was signed. The late middle ages saw the 100 years war between France and England, the plague, the church was fighting, and new ideas grew. Exploration had begun.
