Since his accession to the throne at the age of sixteen, Emperor Wu of the Han Dynasty has brought a new atmosphere to the Han Dynasty in terms of the concept of statecraft, centralization, economic reform, and national defense diplomacy.
The Han Dynasty inherited the Qin system and implemented the system of three princes and nine secretaries in the central government. In addition, Emperor Wu of the Han Dynasty conferred the title of general on his cronies to assist the emperor in handling documents and discussing confidential matters, and was called the Inner Dynasty, and the administrative organs headed by the Prime Minister were therefore called the Outer Dynasty. The power of the three dukes was weakened, but Emperor Wu personally achieved a reasonable balance, and the phenomenon of the prime minister obeying the orders of the inner dynasty was a future development.
The Han Dynasty inherited the Qin system, and implemented the county system in the local area. Emperor Wu divided the country into thirteen prefectures and set up a history of assassination, which was responsible for supervising the county guards and heroes within the state department. The establishment of the prefecture strengthened the centralization of power, the prefecture was not a formal administrative unit, and the Western Han Dynasty still implemented the two-level local administrative operation of the county as a county.
In other words, from the perspective of the operation of the system, Emperor Wu of the Han Dynasty only inherited and adjusted and strengthened the centralization of power, but did not bring fundamental changes to the system. Emperor Wu of the Han Dynasty's greatest contribution to the centralization of power was to subordinate their territories to regular administrative operations for a group of local princes, so that the operation of the three princes and counties could be effectively operated throughout the country.
At the beginning of the Han Dynasty, the parallel implementation of the county and the state brought about the consequence of the closure of the country. When the Western Han Dynasty was founded, the minister's understanding of the death of Qin was that Qin died in isolation, so he adopted a compromise plan, which not only implemented the county system established by Qin, but also reverted to the feudal system. The more serious challenge lies in the division of the two regions, with feudalism on the coast in the east and counties in the interior in the west. Such an arrangement not only allowed the princes to control the areas with better economic conditions, but also easily connected into a line, directly threatening the safety of the central government.
The problem has long been perceived, Emperor Wen of the Han Dynasty implemented the construction of the princes without his strength, and Emperor Jing of the Han Dynasty directly cut the feudal domain and pacified the rebellion of the Seven Kingdoms, and the power of the princes was not as good as before. However, the fiefdoms and generous taxes of the local princes were always a potential threat to the central government, so Emperor Wu of the Han Dynasty took specific measures to complete the goal of cutting the feudal domain since the early Han Dynasty without using force.
Emperor Wu of the Han Dynasty adopted the suggestion of his master father Yan and implemented the Tui En Order, which was called Grace, so that the feudal was not limited to the eldest son, and the other sons could also inherit the land, so the territory of the feudal country became smaller and smaller. In addition, the new lieges were placed under the jurisdiction of the county guards, and their status was the same as that of the county order. Twenty years after the implementation of the Tui'en Order, even the princely powers only had more than ten cities left, and they were no longer able to pose a threat to the central government.
Emperor Wu of the Han Dynasty also implemented other measures to reduce feudal domains. First, under the pretext that the gold quality of the tribute was not enough, he successively cut down more than 100 marquis, which was called the gold and the lord. Second, officials who had served as vassals could no longer serve in the central government, so that people with lofty ideals were unwilling to serve the princes, and the princes lacked strategists.
Emperor Wu of the Han Dynasty accomplished the goal of weakening the power of the local kings, adjusted the administrative system of the central and local governments, revitalized the centralization of power, and consolidated the power of the Western Han Dynasty, which became the main achievements of Emperor Wu of the Han Dynasty.
