Starodub-Siverskyi
Starodub was a Rurikovich appanage in the Severian land, centred on the fortress south of Bryansk. From the thirteenth century it obeyed the princes of Bryansk.
After Lithuania took Bryansk in 1356, Starodub passed with Trubchevsk to the Gediminid prince Dmitry Olgerdovich. It remained a Lithuanian appanage until Ivan III's victory at Vedrosha brought it to Moscow in 1503. The principality was dissolved in 1517. Polish-Lithuanian forces besieged and captured the town in 1535, executing its defenders.
