Reason 3: Political Instability Rome did have a few good rulers, but most were not. They had ineffective and inconsistent leadership, causing people to lose faith in the leadership and lose the overall feel of unity.
Reason 2: Disease (Plague) The plague killed thousands of people, resulting in a decline of agricultural production, trade, and soldiers- this caused economic and protection decline.
Reason 1: Religion When people lose faith in their leaders, their fidelity fails. Christianity contributed to the deterioration of Roman values. No trust is no unity, and what is a country without unity?
