What was one reason for the decline of the Han Dynasty and western Roman empire?

One significant reason for the decline of both the Han Dynasty and the Western Roman Empire was internal strife, including political corruption and social unrest. In the Han Dynasty, power struggles among eunuchs and regional warlords weakened central authority, while in the Western Roman Empire, political instability and civil wars led to a breakdown in governance. Additionally, both empires faced economic difficulties and external pressures from invading groups, exacerbating their decline.
