What was responsible for weakening the Han Dynasty?

The Han Dynasty weakened due to a combination of internal strife, corruption, and external pressures. Political infighting and power struggles among court officials led to instability, while heavy taxation and forced labor caused widespread discontent among the peasantry. Additionally, invasions by nomadic tribes and the rise of regional warlords further eroded central authority, ultimately contributing to the dynasty's collapse in the early 3rd century.
