The Roman Empire lasted for over a thousand years; from 756BC to 476AD. There are many, many reasons that it decreased. At one point it was said that Rome was "more respected than feared." That was said only 42 years before Rome began to decrease .How did this world domination go from being the most powerful empire in the world to completely nonexistent? That is what I"ll be answering in this essay. The last emperor before the decline of Rome began was Marcus Aurelius. He was the third best emperor in Rome's history. He was kind, benevolent, and humane. But during his reign the Pax Romana ended. The Pax Romana is the 200-year period of peace in Ancient Rome. It was said to be "the greatest gift Rome gave to the ancient world." This was one of the first events that started the chain of events that made Rome disapear. One of the most important reasons for the fall of Rome was the economy. There were many economic problems in Rome. I"ll first start with the prisoners of war or the lack there of. When Emperor Hadrian drew the boundaries and said Rome could grow no more in 121 AD, the empire lost one of the three largest sources of income, prisoners of war. Another major source of income was trade. Rome acted like the middleman in trade between the provinces. The provinces were told what to produce, and they produced it, sold it to Rome, who would then sell it to the other provinces for a higher price. But when the provinces became more and more independent, they cut out the middleman all together. So in that action the provinces were taking one of Rome's largest sources of income. The third economic source for Rome was taxes. As the two other sources of income began to disappear, the Rome government raised the taxes for the people of Rome. The taxes skyrocketed and the plebeians, Rome's everyday average poor people who made up almost all of Rome, started to revolt. The next reason for the decline of Rome was that the people neighboring Rome like Germany and Persia grew increasingly hostile toward the Romans.
