Quick Answer: What Were the Three Departments and Six Ministries?

The Three Departments and Six Ministries (三省六部, Sān Shěng Liù Bù) organized central administration under the emperor. The framework took shape in the Sui and became closely associated with the Tang. They divided work on central government business into drafting, review and execution.[1][2][3]

  • Draft: The Secretariat (中書省, Zhōngshū Shěng) prepared policy documents and decrees.[1][2]
  • Review: The Chancellery (門下省, Ménxià Shěng) examined drafts and could send them back.[1][2]
  • Execute: The Department of State Affairs (尚書省, Shàngshū Shěng) supervised the implementation of policy through specialized ministries.[1][2]

The offices held different duties within an administration centered on imperial authority.[1][2][4]

In the Tang model, reviewing a decree and putting it into effect were separate administrative responsibilities.

A decree could pass from the people who wrote it to officials who checked it and then to offices that handled the work. The three departments and six ministries describe where those responsibilities sat in a model of central government.[1][2][4]

What the Three Departments Did

The Secretariat drafted documents on the emperor’s behalf. The Chancellery reviewed them and could propose changes or return a draft. An approved decree carried the emperor’s authority. The Chancellery could return a draft for revision before it moved forward. Once approved and transmitted, the order went to the Department of State Affairs for administrative execution.[1][2]

An edict’s wording and its implementation posed different problems. A draft might need revision before the court accepted it. Carrying it out might involve officials in several offices. This division gave officials defined responsibilities without removing the emperor from the process.[1][2][4]

What the Six Ministries Handled

Under the Department of State Affairs, six ministries, also called boards in some English accounts, had different fields of responsibility. The table gives broad functions. The exact division of tasks changed over the history of these offices.[1][2][3]

MinistryMain field of work
PersonnelCivil appointments, evaluation and promotions
RevenueHouseholds, taxation and fiscal matters
RitesState ritual, ceremonies and examination administration
WarMilitary administration and appointments
JusticePenal administration and review of cases
WorksPublic construction and infrastructure

For example, household records mattered to Revenue, while a matter of civil appointment belonged to Personnel. The court could also have other offices for particular purposes, so the table is a guide to these six units within a larger government.[1][2][3]

How the Model Changed After the Tang

Later courts adapted the model. The Song Yuanfeng reforms of 1082 looked back to the scheme described in the Tang Sixfold Statutes of 738. That reform reorganized offices in a Song setting with its own institutions. Keeping the same names could preserve an ideal of administration while changing what particular officeholders did.[4]

The Ming retained the six ministries as a familiar form of administration. Its arrangements at the center differed from the Tang model. The Grand Secretariat belongs to that later institutional story. A county magistrate handled government at a different level from the court offices described here.[2][4][5]
