The Amur river region was raided by the 1651 Russian expedition of Yerofey Khabarov, after which the indigenous Daur people were either killed or fled away further into territory of the Qing Dynasty's China. Before the Russian conquest, the territory belonged to the Chinese region of Manchuria. The precursor of Primorskaya Oblast was the Albazino Voivodeship that existed 1882-1886 and was abolished upon the conclusion of the Sino-Russian border conflicts. At first it was part of the Eastern Siberian General Government, but beginning 1884 within the Cis-Amur General Government.
