The Department of State Affairs or Shangshu Sheng was one department in the Three Departments and Six Ministries government structure officially established since the Sui dynasty in the history of China. As one of the three departments, it was the highest executive institution of the imperial government since the Sui dynasty. Developing from the Shangshu Tai in the Eastern Han dynasty, the name Sheng was inherited even though the institution was now removed from the Imperial Court. The head of the Department is Shangshu Ling. The Director was known as chancellor but was often absent. The Right and Left Deputy Directors actually shouldered the duties. Beneath the Deputy Directors were the Right and Left Assistant Clerks who had the Right and Left Excellency to assist with their daily work and were in charge of the Six Ministries. The general office of the Department of State Affairs was called the Dou Sheng. The Department controlled the Six Ministries, which included the Ministry of Personnel, the Ministry of Revenue, the Ministry of Rites, the Ministry of Defense, the Ministry of Justice, and the Ministry of the Public Works. During the Jurchen Jin dynasty, the emperor Wanyan Liang abolished the Zhongshu Sheng and the Chancellery in 1156, leaving only the Department of State Affairs in charge of the whole government. This enlarged the power of the emperor, as the Department of State Affairs simply executed the orders of the emperors, who became absolute monarchs. Branch offices of the Department of State Affairs known as the Xing Shangshu Sheng or Xing Tai was established in other parts of the empire. During the Yuan dynasty however, the Zhongshu Sheng replaced the Department of State Affairs as the top government agency. The Department of State Affairs was additionally institutionalized in 1270, but was soon abolished in 1272. The head of the Department was normally a single Director. It was established again in 1287 and 1309, but was likewise abolished in 1291 and 1311 respectively, after which the Zhongshu Sheng alone served. The Department of State Affairs was established in these short periods to deal with financial affairs such as during the "New Deals" of Külüg Khan, who also changed the branch offices of the Zhongshu Sheng to those of the Department of State Affairs or Xing Shangshu Sheng before it was changed back by his successor Ayurbarwada Buyantu Khan. The early Ming dynasty adopted the Yuan Zhongshu Sheng, but the Department of State Affairs was never again established. The abolishment of the Zhongshu Sheng by the Ming in 1380 marked the end of the Three Departments system.
