By the beginning of the fourth century, the Roman Empire had become a completely different economic reality from what it had been at the beginning of the first century. The denarius argenteus, the empire’s monetary unit during the first two centuries, had virtually disappeared since the middle of the third century, having been replaced by the argenteus antoninianus and the argenteus aurelianianus, numerals of greater theoretical value, but of less and less real value.
The public excesses in the civil and military budgets, the incessant bribes and gifts, the repeated tax increases, the growth of the state bureaucracy, and the continuous requisitions of goods and precious metals had exhausted the Roman economy to incredible levels. To cap this disastrous reality, inflation had risen from 0.7 percent per year in the first and second centuries to 35.0 percent per year in the late third and early fourth centuries, impoverishing all social strata of the empire by leaps and bounds.
