There were many reasons for the fall of rome and they were all spread out of hundreds upon hundreds of years, but there were some that contributed more than others. One large factor was the major economic downturn and massive inflation. A bag of grain that would have otherwise costed 5 drachma then costed 120,00. Romans were also continuously importing luxury resources which they actually couldn't afford. Another reason which was possibly the biggest was the failure to hold of barbarians which eventually led to them destroying the western roman empire. The lack of military strength because of bad economy and other factors led to this happening. The third large reason was the growth of the government. Diocletean expended the Roman buerocracy in an attempt to organize the government but it backfired and led to many dishonest and corrupt officals having power. The last major reason was the decline in the worker force. Since taxes were going so high and people were being forced to work many people were dying and thus leading to a lack of workers. I think that the largest factor to the fall of Rome was their failure to hold off the barbarians. When Diocletean tried to integrate them into society it just led to revolts and the Roman military was unable to supress them which eventually led to the end of Rome.
