Roman, eldest son of Glaib, and once prisoner in Vladimir, had married a daughter of Sviatoslav, the Kief prince, and had thus become an ally of “the sister’s son.” In 1180 Roman’s brothers turned to Vsevolod of Vladimir, saying: “Thou art our lord and father; settle between us and Roman, who takes away our land at the advice of his brother-in-law, Sviatoslav.” Vsevolod moved against Roman, who met him at Kolomna. Sviatoslav sent his son Glaib from Kief to aid Roman. Vsevolod invited this son of Sviatoslav to meet him and negotiate. Glaib was unwilling to do so, but as Kolomna was occupied by Vsevolod, he had to accept the inevitable. Upon his arrival, Vsevolod ordered him put in chains and sent him to Vladimir, whither he sent all the men and property seized by Glaib’s warriors, commanding that both man and property should be kept under strong guard. Roman, leaving his two younger brothers in Ryazan to defend it, fled to steppe regions. When Vsevolod marched to Ryazan, the princes submitted, whereupon he made peace and apportioned the principality between them. All kissed the cross to Vsevolod, even Roman, who returned now and joined his brothers. When he heard that his son had been captured, Sviatoslav was tremendously indignant, and went at once to Chernigoff. In Chernigoff, at that time, ruled Yaroslav, brother of the Kief prince. Of the younger princes, there were present in the city Igor, son of Sviatoslav, and his brother, Vsevolod the “Rushing Bull,” as he is called by a Russian poet. With them were their sons just reaching maturity. All had taken to heart the offense which Sviatoslav had suffered. After they had counseled together and were agreed, Sviatoslav addressed them in these words: “As a father, I command you to act as follows: thou, Igor, will stay with Yaroslav, my brother, to guard Chernigoff, while I will go to Suzdal to free my son from Vsevolod. And let God judge between us.” Sviatoslav left one half of his forces in Chernigoff, and led away the other half, taking with him a man who was his guest at that time, Yaropolk Bezoki. Sviatoslav’s son, Vladimir, who had become prince in Novgorod after the death of Mystislav, was to meet his father on the road. The allies from North and South assembled in lands within the Tver boundaries, and marched toward Pereyaslavl.
