The "grand coordinator" of the
Ming dynasty (1368–1644) was one of several institutional innovations promoted by the
Xuande Emperor (r. 1425–1435). Following precedents set by the
Hongwu and
Yongle emperors, who had sent officials on temporary civilian and military missions in the provinces, in September 1425 Xuande appointed officials to "tour and pacify" (
xunfu) two southern provinces. Five years later, three more officials from the central government were sent to
Henan,
Shaanxi, and
Sichuan on similar assignments. There is also evidence that more "touring pacifiers" were sent to the field between 1425 and 1430, when the position did not yet formally exist. In 1435, grand coordinators were also dispatched to provinces on the northern borders of the Ming empire, from
Gansu in the west to
Liaodong in the east. Eventually there were grand coordinators in every province. Grand coordinators could also take charge of strategically important regions that were not provinces. In 1547, one was sent to curb smuggling and
piracy on the coasts of Fujian and Zhejiang. Another one was appointed to
Tianjin to protect access to Beijing in 1597 during a large-scale
Japanese attack on Korea. Grand coordinators were members of no specific agency and only received ad hoc commissions with no definite tenure. They managed and oversaw provincial government by coordinating the work of the three highest provincial agencies: the Provincial administration commission (
buzheng si 布政司), the Provincial surveillance commission (
ancha si 按察司), and the Regional military commissioner (
du si 都司). Because grand coordinators were also high-ranking members of the
Censorate, they had impeachment powers and direct access to the throne, which considered them to be "provincial-level surrogate[s] of the emperor". Although they were civil officials, they also received military titles when they had to supervise important military matters. ==Qing governor==
