Chernihiv

The Principality of Chernihiv was a Rus realm centered on the Desna basin. After the Mongol invasion its center shifted to Bryansk. In 1337 Gleb ruled Chernihiv.

The principality accepted Lithuanian grand duke Gediminas's suzerainty in the early 1320s; Algirdas attached it to Lithuania in 1356—1357. Its last grand prince, Roman Mikhailovich, was killed at Smolensk in 1401. After the war of 1500—1503, Chernihiv and neighboring Severian towns passed to Ivan III of Moscow.
