Vitebsk Governorate
The south of Pskov Oblast was transferred to Polotsk Governorate, which in 1777 became Polotsk Viceroyalty. In 1796, the viceroyalty was abolished and the area was transferred to Belarus Governorate; since 1802 to Vitebsk Governorate. After 1919, Vitebsk Governorate was a part of Russian Soviet Federative Socialist Republic. In 1924, Vitebsk Governorate was abolished, and Sebezhsky, Nevelsky, and Velizhsky Uyezds were transferred to Pskov Governorate.
