The document summarizes the decline of the Roman Empire from the late 2nd century AD to the 5th century AD. It discusses economic problems, agricultural decline, overtaxation, and inflation that weakened Rome. Military issues like less disciplined troops and declining patriotism also hurt Rome. Emperors like Diocletian and Constantine tried reforms to bolster the military and split the empire but this did not stop invasions by Germanic tribes and Attila the Hun. By 476 AD, the Western Roman Empire had collapsed with the ousting of the child emperor Romulus Augustulus.
