History
The Lovat River was a part of the trade route from the Varangians to the Greeks, one of the oldest trading routes passing through Rus'. This branch of the route followed the Lovat upstream and then the Usvyacha and the Western Dvina. The area was populated since the Middle Ages, and Usvyaty (Vsvyach) was first mentioned in chronicles under 1021. The area was changing hands multiple times between Russia and Poland, eventually went to Poland and stayed there until the First Partition of Poland in 1772, when it was included into newly established Pskov Governorate, a giant administrative unit comprising what is currently Pskov Oblast and a considerable part of Belarus. After 1773, the area was split between Nevelsky and Velizhsky Uyezds of Pskov Governorate. In 1777, it was transferred to Polotsk Viceroyalty.
