Principality of Pereyaslavl

The Principality of Pereyaslavl was a regional principality of Kievan Rus' on the left bank of the middle Dnieper, centred on the city of Pereyaslavl (today Pereiaslav in Ukraine) on the Trubizh river. The Primary Chronicle dates the city's foundation to 992, and from the late ninth century the surrounding land was organised as a dominion of the Kievan princes. Pereyaslavl was usually assigned to a younger son of the Grand Prince of Kiev; in the division of Yaroslav the Wise's inheritance it passed to Vsevolod, and it remained one of the most important principalities of Rus' after Chernigov and Kiev. Its territory stretched eastwards towards the Seversky Donets, where the Cuman city of Sharukan was said to lie. The principality was devastated by the Mongols in March 1239, after which the city was largely abandoned and the land became tributary to the Golden Horde. Some historians trace the title to 1323, but by then the principality had long ceased to function as an independent polity. In the 1360s the region was acquired by Algirdas of Lithuania.
