Novgorod Governorate
In the course of the administrative reform carried out in 1708 by Peter the Great, the territory was included into Ingermanland Governorate (known since 1710 as Saint Petersburg Governorate). In 1727, separate Novgorod Governorate was split off, and in 1772, Pskov Governorate was established (existing between 1777 and 1796 as Pskov Viceroyalty). In 1776, Porkhovsky Uyezd was transferred from Novgorod Governorate to Pskov Governorate. Soltsy was the seat of Soletskaya Volost of Porkhovsky Uyezd.
