The area was originally populated by speakers of Uralic languages and then colonized by the Novgorod Republic. It was located on the trading route connecting central and northern Russia, from Moscow to the White Sea along the Onega River. After the fall of Novgorod, the area became a part of the Grand Duchy of Moscow. The descendants of the Novgorod population are the Pomors who inhabit the White Sea coast and traditionally are engaged in fishery. Many localities in the district along the coast, such as Unezhma (now abandoned), have historical significance as old Pomor villages. The western coast of the Onega Bay is known as the Pomor Coast (Pomorsky Bereg).
