Могилёвская губерния
Between second half of the 14th century and the middle of the 17th century, the area belonged intermittently to the Grand Duchy of Lithuania, to Poland, and to the Grand Duchy of Moscow. In the 18th century, much of the area belonged to Poland, and in 1772, as a result of the First Partition of Poland, it was transferred to Russia and included in the newly established Mogilev Governorate. It belonged to Mstislavsky Uyezd. In 1919, Mogilev Governorate was abolished, and Mstitlavl Uyezd was transferred to Smolensk Governorate. On 3 March 1924, a half of Mstislavsky Uyezd was transferred to Byelorussian Soviet Socialist Republic, and seven volosts were left in Smolensk Governorate. In 1925, Monastyrshchina Volost was established.
