reasons why Rome fell

1.) The internal factors that led to the collapse of the Roman empire include military overreach, invasion by emboldened tribes of Huns and Visigoths from northern and central Europe, inflation, corruption and political incompetence. In the economic taxes were raised
and socially, disease and starvation were occurring. Less people were educated. Emperors like Constantine ensured that the city of Constantinople was fortified and well guarded, but Italy and the city of Rome—which only had symbolic value for many in the East—were left vulnerable. As the situation worsened, civic pride waned and many Roman citizens lost trust in their leadership.

2.) Unable to recruit enough soldiers from the Roman citizenry, emperors like Diocletian and Constantine began hiring foreign mercenaries to prop up their armies. Germanic soldiers of fortune had little or no loyalty to the empire, and their power-hungry officers often turned against their Roman employers. Many barbarians sacked the city of Rome and brought down the Western Empire.
The empire stopped expanding and the government raised taxes which caused hardships poor romans found it harder to get educated. Distributing news across the empire became more difficult

3.) Describe the impact of Christianity on Roman rule.

Christianity being legalized in 313, and it later became the state religion in 380. These decrees ended centuries of persecution, but they may have also eroded the traditional Roman values system. Church leaders were began complicating the roman government. Christianity curbed romans civic virtue.
