Why did Ancient Rome fall?

A whole variety of reasons can be suggested to explain the fall of the Roman Empire in the west: disease, invasion, civil war, social unrest, inflation, economic collapse. In fact all were contributory factors, although key to the collapse of Roman authority was the prolonged period of imperial in-fighting during the 3rd and 4th century.

Conflict between multiple emperors severely weakened the military, eroded the economy and put a huge strain upon local populations. When Germanic migrants arrived, many western landowners threw their support behind the new ‘barbarian’ elite rather than continuing to back the emperor.

Reduced income from the provinces meant that Rome could no longer pay or feed its military and civil administration, making the imperial system of government redundant. The western half of the Roman empire mutated into a variety of discrete kingdoms while the east, which largely avoided both the in-fighting and barbarian migrations, survived until the 15th century.
