Смоленская губерния
In the course of the administrative reform carried out in 1708 by Peter the Great, the area was included into Smolensk Governorate and remained there until 1929, with the exception of the brief period between 1775 and 1796, when Smolensk Governorate was transformed into Smolensk Viceroyalty. The area was split between Dukhovshchinsky, Krasninsky, Porechsky, and Smolensky Uyezds.
