There was much suppressed dissatisfaction among the nobles, and many plots were hatched against him. In the year of his coronation, a fire swept wooden Moscow, and about 1,700 people perished in the flames. Ivan ordered an investigation, and withdrew to Vorobief. Crowds gathered in the thoroughfares, when mysterious persons appeared among them declaring that the Glinskis had set the city on fire. Soon after shouts were heard, "It is the Princess Anne Glinski who, with her two sons, has bewitched the city; she has taken human hearts, plunged them in water, and with this water has sprinkled the houses. This is the cause of the destruction of Moscow!" A mob collected and made for the palace of the Glinskis and one of them, George, was stabbed. They went on to Vorobief, where they demanded the life of Ivan's uncle. The czar's own life was in danger and the mob had to be dispersed by force. Ivan did not forget this, and terrible was his vengeance upon the (p. 115) boyards. At this time he gave his confidence to two men, one a priest named Silvester, who had the reputation of being a very honest man; the other, a member of the smaller nobility, named Adachef who, in 1551, as Minister of the Interior, gave to Russian cities the first municipal liberties. Ivan showed an unusual interest in the people; it was under his orders that a new code of laws (Soudebnik) was prepared, and many reforms were made in the Church. This rather increased than diminished the hostility of the nobles. Ivan's favorites, Silvester and Adachef had grown ambitious and the former especially was overbearing. He openly opposed the czar, and tried to sow discord between him and his wife. When Ivan's favorite son died, Silvester told him that it was a punishment from heaven for his disobedience. The two men tried to procure the dismissal of the Glinskis and Romanofs, and for that purpose made friends with the boyards whom Ivan suspected. In 1553, the czar fell dangerously ill; he called in the boyards and ordered them to swear loyalty to his infant son Dmitri. They refused. He was informed that the nobles were conspiring with his cousin Vladimir, whose mother was distributing money in the army. He was in terror for the lives of his wife and son. Once he said to the boyards who had remained faithful, "Do not, I pray you, forget that you have sworn an oath to my son and to me; do not let him fall into the hands of the boyards; fly with him to some foreign country, whithersoever God may guide you." Ivan recovered but he never could forget the anguish of those days.
