Zygmunt Gloger in his monumental book Historical Geography of the Lands of Old Poland provides this description of the Mscislaw Voivodeship:
“Mscislaw (Mscislavia), which lies at the Wiechra river, was probably founded in the late 13th century, and named after Duke of Smolensk, Mstislav Romanovich the Old. In the 14th century, it was captured by the Grand Duchy of Lithuania, and for a while remained a fief (...) By 1538, the Duchy of Mscislaw was already governed by a starosta, who during the reign of King Zygmunt August was renamed into a voivode, while the Duchy was turned into a voivodeship. First Voivode of Mscislaw was Jerzy Oscik, Traby coat of arms.
The Voivodeship of Mscislaw was not divided into counties (see powiat). Its sejmiks took place at Mscislaw, where two deputies to the Sejm were elected, and two to the Lithuanian Tribunal (...) It ceased to exist in 1772, when after the first partition of Poland, Mscislaw Voivodeship was annexed by the Russian Empire".
