What major events led to the decline and fall of the Roman Empire? Categorized between internal and external factors with broad reasoning, it does not lend itself to just a few events as the cause of the actual fall. From internal factors: socio-economic problems and political corruption with the emperors and the senate with their selfish and indulgent lifestyle with the gladiatorial games representing a major expense for the coffers, the moral decline affected the richest Romans with the 'immorality, various kinky sexual behaviors, gambling on most activities, and public sexual/obscene acts in the Colosseum. Education became only for the rich and usually only for males. Basic standards of ethics and values ​​were lost with total disregard for human and animal life, cheap slave labor led to greater unemployment for the plebeian working class which underlined the continuing gap from the wealthy patricians. From external factors: constant wars and heavy armed forces In terms of expenses, the large Roman army was excessively expensive, struggling to maintain experienced warriors, recruiting more and more soldiers, and then turning to hiring mercenaries and barbarians. By adding more soldiers from the conquered lands, those barbarians soon became more similar to the Romans and consequently less capable of fighting other barbarians from other countries. With the army reduced to all borders, when a problem grew it could quickly become overwhelming as with the Visogoths, once allowed to settle on the southern bank of the Danube, the living conditions of poverty and hunger led them to attack, then to move and sack the city of Rome. Then there were natural disasters such as famines, earthquakes and plagues. With the influx of barbarians and many newcomers from the invaded countries, the manifestation of serious diseases, the transfer of plagues and the lack of constant medical care repeatedly perpetuated all natural disasters.
