Helena, as regent, appears to have governed well. She did not marry again, thus the rights of Ivan and his brother Yuri were not endangered by her. Her lover, Kniaz Telepniev, for a time kept at bay the rival factions of the more powerful nobles, and possibly was instrumental in thwarting the plots of the Glinski. At Helena's command two of her relatives were executed for conspiring against the infant Tsar. She enclosed the Kitai Gorod with a wall of stone; improved the defences of Moscow in other ways, gave the people a new coinage, founded monasteries, built churches, and continued the policy of the rulers of Moscow. Five years after her husband's death she died suddenly, of poison it is said, and the rumour may be credited. In 1538, Ivan, then in his eighth year, and his brother Yuri, his junior by eighteen months, were left to the mercies of the most powerful factions about the court. They were neglected; Ivan himself said of this period, "we two were treated as strangers: even as the children of beggars are served. We were ill clothed, cold, and often went hungry." Jealous of each other the courtiers would not allow the princes to attach themselves to anyone. If Ivan felt drawn to anyone, or any person took notice of him, all the others combined to separate the two. The Shooiskis were then the most powerful family, and Shooiski treated Ivan with scant consideration. His tutors encouraged him to ride at full speed through the streets and try to knock down the old and feeble; they allowed him to have animals tortured for his diversion, and laughed with him at their plight when flung from the roof of the palace. Ivan learned to read, and spelled through all the books he could obtain. From these old chronicles,--from those of the Kings of Israel, to the doings of his own ancestors--he seems to have obtained the idea of the powers of sovereignty. A close observer he noticed that although ordinarily he was treated as of little account, when any act of state had to be done he was always summoned to give the command. Young as he was, Ivan knew his importance. One day, when he was thirteen years old, he went out sporting with Gluiski, and Gluiski incited him to repress the arrogance of Shooiski. Ivan did it by having Shooiski pulled out into the street and worried to death there and then by Gluiski's hounds.
