until 1054. Subsequently, his son who would eventually be titled Grand Prince Sviatoslav initiated the Chernigov branch of the Rurikids. During the civil war of the Yaroslavichi, Chernigov was contested between the sons of Sviatoslav and Vsevolod. After the death of Sviatoslav in 1076, it came to the decision of the Council of Liubech, that the sons of Sviatoslav, Oleg and Davyd, and their descendants secure the principality. The principality subsequently obtained a certain degree of autonomy and was primarily secured thereafter. The Principality was later split into three main apanage principalities: Chernigov proper, Novgorod-Seversk, and Murom-Ryazan. While Tmutarakan, due to its remoteness, often became contested and eventually was overtaken. Murom and later the Ryazan principality drifted away from the influence of Chernigov and after some time was contested by the Principality of Vladimir. Nonetheless, the influence of the Chernigov princes remained large and they retained the title of Grand Prince of Kiev for some time. Chernigov was one of the largest economic and cultural centers of Kievan Rus'.
