PRINCES of NOVGOROD-SEVERSKIY and KURSK-mg.ac/Projects/MedLands/RUSSIA,%20Rurik.htm#SviatoslavOlegovichdied1164B

The principality of Novgorod-Severskiy was created in 1139, its territory being carved out of the principality of Chernigov. The town of Novgorod-Severskiy lies on the River Dnesa upstream of Chernigov in a north-easterly direction. Although the boundaries between the two principalities are hard to identify, it appears that Novgorod-Severskiy governed the southern half of the territory while Chernigov continued to govern in the northern and western areas[686]. The principle of lateral succession appears to have applied to Novgorod-Severskiy, the ruling prince being succeeded by the next most senior male member of his own generation before the succession passed to the subsequent generation. The members of the family shown below are named by Baumgarten with reference to primary sources[687].
