Мста
The Msta River was an important waterway since at least the 10th century, since it connected Novgorod with the basins of the Volga and the Northern Dvina. In the course of the administrative reform carried out in 1708 by Peter the Great, the area was included into Ingermanland Governorate (known since 1710 as Saint Petersburg Governorate). In 1727, separate Novgorod Governorate was split off. In 1776, the area was transferred to Novgorod Viceroyalty. In 1796, the viceroyalty was abolished, and the area was transferred to Novgorod Governorate.
