1435 CE
Yishiha, a eunuch of Haixi Jurchen derivation, had been ordered to lead an expedition to the mouth of the Amur to pacify the Wild Jurchens when the Ming dynasty under the the Yongle Emperor established the Nurgan Regional Military Commission on the banks of the Amur River in 1409.
The Nurgan Regional Military Commission is abolished in 1435, and the Ming court ceases to have substantial activities here, although garrisons will continue to exist in Manchuria.
