Principality of Chernigov
Gleb Vladimirovich, son of Vladimir the Great, ruled the principality in the early eleventh-century. Murom was part of the territory of the Principality of Chernigov in the late eleventh-century, controlled by the Sviatoslavichi clan, the descendants of Iaroslav the Wise; probably it was retained by Vsevolod Iaroslavich even after this Prince of Chernigov became Grand Prince in 1076.
