Legalism helped lead to rebellions after Shi Huangdi's death because under Legalism, a minor crime received punishments that
were often severe and harsh. The Legalist philosophy prioritized the power of the ruler and the strict enforcement of laws, which often resulted in excessive punishments for even minor offenses. The punishments were meant to deter people from committing any wrongdoing, but they ended up creating a climate of fear and resentment among the people.
After Shi Huangdi's death, his son and successor, Qin Er Shi, did not possess the same level of leadership skills as his father. He was unable to maintain the strict rule of Legalism, and there was a gradual loss of control over the empire. The implementation of harsh punishments without regard for individual circumstances or fairness caused widespread dissatisfaction.
As a consequence, these severe punishments triggered resentment among the people, and rebellions and uprisings began to arise. The people felt oppressed and suppressed by the Legalist system and saw the government as an oppressive force rather than a benevolent ruler. This led to dissent and ultimately rebellion against the ruling class.
Additionally, the strict implementation of Legalism undermined the morale and loyalty of the officials and generals who served in Shi Huangdi's administration. They saw their authority being undermined, and their power and influence being diminished, which further added to the disarray within the empire.
In summary, the rigid enforcement of Legalism and its harsh punishments created an atmosphere of fear and resentment among the people, leading to rebellions and uprisings after Shi Huangdi's death. The consequences of the legalist philosophy undermined the stability and control of the Qin Dynasty, ultimately leading to its downfall.
