Yaroslav the Wise also accepted the division of Kievan Rus' along the river after Mstislav had defeated him in a battle fought at Listven by Chernigov.

[3] Historians debate whether the future prince of Tmutarakan and Chernihiv was the son of Rogneda or Vladimir's Czech wife: the first option is preferred by George Vernadsky, the second by Janet Martin.

[1][3] Vladimir the Great administered large portions of Kievan Rus' through his sons by placing them in towns in the borderlands.

[1][5] The Primary Chronicle narrates, under the year 988, that Mstislav became the prince of Tmutarakan after the death of one of his brothers, Vysheslav of Novgorod.

[9] Under Mstislav, who was the first known prince of Tmutarakan, the town developed into an important emporium for traders from the Kievan Rus' and the Byzantine Empire.

[1] Mstislav remained neutral during the civil war which followed his father's death and ended with the victory of his brother, Yaroslav the Wise in 1019.

[11] The Byzantine chronicler John Skylitzes writes of one "Sphengos, the brother of Vladimir"[12] who assisted the imperial fleet in attacking "Khazaria" in 1016.

Rededia later, in his dying breaths, insisted that his comrades not hold a blood vendetta to avoid further gruelling wars for the Kassogians who had already fought the Mongols previous to Mstislav's campaign.

Rededia's legacy was immortalized by his fellow Kassogian bards and his name continues to live even in modern Circassian minstrels, poems and folk songs.

[31] He was buried in the Transfiguration of the Holy Savior Cathedral which had been by that time "built to a point higher than a man on horseback could reach with his hand".
