He sent a powerful army to descend the banks of the Dnieper, capturing all the cities on the right hand and on the left, and binding the inhabitants by oaths of allegiance.

The army advancing with resistless strides arrived before the walls of Kief, took possession of the deserted palaces of this ancient capital, and Sviatoslaf proclaimed himself monarch of southern Russia.
But while Sviatoslaf was thus prosecuting his conquests, at the distance of four hundred miles south of Novgorod, Vsevelod advanced with an army to this city, and was in his turn received by the Novgorodians with the ringing of bells, bonfires and shouts of welcome.

All the surrounding princes and nobles promptly gave in their adhesion to the victorious sovereign, and Sviatoslaf found that all his conquests had vanished as by magic from beneath his hand.
Under these circumstances, Vsevelod and Sviatoslaf were both inclined to negotiation.

As the result, it was agreed that Vsevelod should be recognized as the monarch of Russia, and that Sviatoslaf should reign as tributary prince of Kief.

To bind anew the ties of friendship, Vsevelod gave in marriage his beautiful sister to the youngest son of Sviatoslaf.
