Shortages of gold and silver was a key factor in making Rome fall. Tribunes & Triumphs say the amount of gold sent to the orient to pay for luxury goods led to a shortage of gold to make Roman coins. Roman currency was
devalued to such an extent that a system of bartering returned to one of the greatest civilisations the world had ever known. Ancient Economic Collapses explains that one of the primary catalysts to the deterioration of the Roman economy was the lack of circulating currency in the Western Empire. Two reasons for the lack of funds are wholesale hoarding of bullion by Roman citizens, and the widespread looting of the Roman treasury by the 'barbarians'. And Annika Spaford states this in her Prezi. Once they were out of gold and silver the empire no longer could produce coinage to trade with foreign merchants this meant that the Roman Empire was forced to trade item instead of valuable coins and ultimately decreasing the value of Roman trade. This created inflation and from the amount of money Rome used on providing bread and homes for the poor. Clearly late Rome had poorly planned for its growing economic weaknesses. Evidence of this inflation comes from tribunes and tributes The Government was constantly threatened by bankruptcy due to the cost of defending the Empire, the failing economics, heavy taxation and high inflation.
Communication was extremely limited in ancient and controlling one of the world’s largest Empires was difficult with first century technology. Rome being located in almost the middle of the empire meant that it was almost the same distance to deliver messages from north to south, east to west. Hence Diocletian and the Tetrarchy in 285 AD
