Novgorod-Siverskyi

Novgorod-Seversk was a Rurikovich principality on the middle Desna and Seim, centred on Novhorod-Siverskyi. After the Mongol invasions it passed to the princes of Bryansk and then Lithuania.

In 1454 Casimir IV granted the principality to Ivan Shemyakin, a fugitive prince from Moscow. His son Vasily entered Ivan III's service, and the truce of 1503 confirmed the territory as Muscovite. Vasily, the last appanage prince, died in prison in 1523, when the principality was abolished.
