In the excess of his zeal of benevolence he was disposed to forgive all criminals. Thus crime was greatly multiplied, and the very existence of the state became endangered. The clergy, in a body, remonstrated with him, assuring him that God had placed him upon the throne expressly that he might punish the wicked and thus protect the good. He felt the force of this reasoning, and instituted, though with much reluctance, a more rigorous government. War had been his passion. In this respect also his whole nature seemed to be changed, and nothing but the most dire necessity could lead him to an appeal to arms. The princess Anne appears to have been a sincere Christian, and to have exerted the most salutary influence upon the mind of her husband. In the midst of these great measures of reform, sudden sickness seized Vlademer in his palace, and he died, in the year 1015, so unexpectedly that he appointed no successor. His death caused universal lamentations, and thousands crowded to the church of Notre Dame, to take a last look of their beloved sovereign, whose body reposed there for a time in state, in a marble coffin. The remains were then deposited by the side of his last wife, the Christian princess Anne, who had died a few years before. The Russian historian, Karamsin, says: "This prince, whom the church has recognized as equal to the apostles, merits from history the title of Great. It is God alone who can know whether Vlademer was a true Christian at heart, or if he were influenced simply by political considerations. It is sufficient for us to state that, after having embraced that divine religion, Vlademer appears to have been sanctified by it, and he developed a totally different character from that which he exhibited when involved in the darkness of paganism." One of the sons of Vlademer, whose name was Sviatopolk, chanced to be at Kief at the time of his father's death. He resolved to usurp the throne and to cause the assassination of all the brothers from whom he could fear any opposition. Three of his brothers speedily fell victims to his bloody perfidy. Yaroslaf, who had been entrusted with the feudal government of Novgorod, being informed of the death of his father, of the usurpation of Sviatopolk and of the assassination of three of his brothers, raised an army of forty thousand men and marched upon Kief. Sviatopolk, informed of his approach, hastened, with all his troops to meet him. The two armies encountered each other upon the banks of the Dnieper about one hundred and fifty miles above Kief. The river separated them, and neither dared to attempt to cross in the presence of the other. Several weeks passed, the two camps thus facing each other, without any collision.
