Novgorod Land was subdivided into five pyatinas. The division was first mentioned in the end of the 15th century and was in use after Novgorod was taken over by the Grand Duchy of Moscow. It is unclear whether the division existed in the Novgorod Republic. The division into pyatinas was abolished in the 18th century, after the governorates were established.
