Meng Tian
When Fusu, Qin Shi Huang's eldest son and the crown prince, was exiled to work at the northern border for disputing his father's policies, Meng Tian was ordered to assist the prince — a task he had accomplished loyally. When Qin Shi Huang died, Meng Tian's death was caused by Zhao Gao who forged a letter from Qin Shi Huang. He was forced to commit suicide in prison, and his family was killed. Three years after his death, the Qin dynasty collapsed.
