Legalism

Explanation:

Legalism is a Chinese philosophy. This was the philosophy used by Qin Shi Huangdi, the founder of Qin Dynasty. Unlike other philosophies, legalism focuses on "social order." This means that, in order to achieve a good order in the society, the society has to be grounded on rules. This allowed the government to be powerful during this era because people needed to follow the rule all the time. If they commit any wrongdoing, they will be punished which became a threat to the society. This made the philosophy very unpopular, especially that it was considered above all other religious doctrines.
