Three Departments and Six Ministries

Before the Three Departments and Six Ministries, the central administrative structure of the Qin and Han dynasties was the Three Lords and Nine Ministers (三公九卿, Sāngōng Jiǔqīng) system.

Under the reign of Emperor Wen of Wei (r. 220–226), the Central Secretariat was formally created to draft imperial edicts and to balance out the powerful Department of State Affairs[1] The office of the Chancellery was first instituted during the Jin dynasty (266–420) and carried on throughout the Northern and Southern Dynasties period (420–589), where it often became the most powerful office in the central government.

The position of Chief Steward for writing (shangshu) became more important during the reign of Emperor Wu of Han (r. 141-87 BC), who tried to escape the influence of the Grand Chancellor and Censor-in-Chief(yushi dafu 御史大夫) by relying on other officials.

Emperor Guangwu of Han (r. 25–57) created the Department of State Affairs with the shangshu as head of the six sections of government.

However, by the mid-Tang period the Grand Chancellors had regained their predominance, and Vice Directors of the department were required to have special designations to participate in policy making discussions.

The six divisions were replicated at the local prefectural level, and each directly reported to their respective ministries in the central government.

[4] The Six Ministries (六部 Liù Bù), also known as the "Six Boards," were government agencies directed by the Department of State Affairs and formally institutionalized during the Cao Wei and Jin dynasty (266–420) periods.

The succeeding Ming dynasty (1368–1644) abolished the Central Secretariat entirely and put the Six Ministries under the direct control of the emperor.

The chief steward for writing (shangshu 尚書), aided by eunuch secretary-receptionists (zhongshu yezhe 中書謁者)), forwarded documents to the inner palace.

This institution continued after the end of the Han dynasty into Cao Wei and it was Emperor Wen of Wei who formally created the Central Secretariat, headed by a Secretariat Supervisor (zhongshu jian 中書監) and a Director (zhongshu ling 中書令).

Although lower in rank than the Department of State Affairs, the personnel of the Central Secretariat worked closer to the emperor and were responsible for drafting edits, and therefore their content.

In the Northern and Southern dynasties, the personnel ranged from princes and high ranking family members to professional writers.

The position and responsibilities of the Central Secretariat varied greatly in this period, sometimes even being put in charge of judicial and entertainment matters.

Emperor Gaozong of Tang (r. 618–626) called it the "Western Terrace" (xitai 西臺), Wu Zetian (regent 684–690, ruler 690–704) called it the "Phoenix Tower" (fengge 鳳閣), and Emperor Xuanzong of Tang (r. 712–755) named it the "Department of the Purple Mystery" (ziweisheng 紫微省).

During the Sui-Tang period, the duty of the Central Secretariat was to read incoming material to the throne, answer questions from the emperor, and to draft imperial edicts.

However the title of Director remained an honorific while real leadership of the Central Secretariat went to the Right Vice Director of the Department of State Affairs (shangshu you puye 尚書右仆射, or youcheng 右丞), who also held the title of Court Gentleman of the Central Secretariat (zhongshu shilang 中書侍郎).

The Left Vice Director (zuo puye 左仆射, or zuocheng 左丞) held the titles of Court Gentleman of the Chancellery (menxia shilang 門下侍郎) and Grand Chancellor concurrently.

[14] The Jurchen dominated Jin dynasty (1115–1234) had a Central Secretariat that functioned similarly to the Song institution, but the paperwork was done by academicians rather than professional drafters.

Below the state counsellors there were four consultants (canyi zhongshusheng shi 參議中書省事) responsible for paperwork and took part in decisions.

These new external duties were reduced in the Tang dynasty (618–907) to just the city gates, the insignia, and the Institute for the Advancement of Literature.

The position of supervising secretary originated in the Department of State Affairs, from where they were transferred to the Chancellery in the early Tang period.

[19] The Chancellery began to decline in significance during the mid-Tang period as it competed in political power with the Central Secretariat.

[20] The Chancellery only continued to exist in name during the Song dynasty (960–1279) while its functions were carried out by the Central Secretariat and the Department of State Affairs.
