Final answer:
Legalism enabled Qin Shi Huang to enact his imperial policies by centralizing command over state resources, gaining popularity among the common people, and being held in check by ministers.
Step-by-step explanation:
Legalism enabled Qin Shi Huang to enact his imperial policies in several ways. Firstly, Legalist doctrine allowed the emperor to centralize command over state resources. This meant that Qin Shi Huang could easily control and allocate resources for his policies. Secondly, Legalism's focus on justice made Qin Shi Huang popular among the common folk. This popularity helped him gather support and implement his policies effectively. Finally, under Legalism, the emperor was held in check by his many ministers. This system of checks and balances ensured that the emperor did not abuse his power and allowed for a more stable governance.
