In the hush that had followed his first words his voice carried clear to all the crowding men. When he finished there came a silence, and then of a sudden cheer on cheer rose on the stairs and through the hall. "Peter, the son of Alexis! Hail Peter! Hail the two boy Czars!" The nearest soldiers dropped the points of their spears and joined in the shouting. A flush came into the younger boy's face and he smiled, and squeezed Ivan's hand tighter. He knew that the danger had passed. Slowly the soldiers who had climbed nearest to the boys drew back down the stairs. Swords were returned to scabbards, harsh voices grew quieter, and within a quarter of an hour the Red Staircase and the great hall were empty of men. Then the door of the room from which the two boys had come opened, and Natalia and her women stepped out. The Czarina, a woman of courage herself, took Peter in her arms. "My brave son," she murmured, "thou art worthy of thy father. I would have stood beside thee, but the people hate me, and it would have been worse for us all." "I needed no one, little mother," said Peter. "If I am ever to be a ruler I must not fear to face my own men." Then his face grew more serious. "But if I ever am Czar they will not break into the Kremlin this way, mother, nor wilt thou need to hide thyself from them." "God grant it be so, Peter!" answered Natalia. "I think they've learned much from thee this very day." The Streltsi had indeed learned that the boy Peter was no coward, and their dislike changed to affection; but there were others in Moscow who plotted and planned against him, because the family of the late Czar's first wife were very powerful in Russia and they hated his second wife Natalia, and her son, who had been his father's favorite. Everything that conspirators could do to break the boy's spirit was done; he was time and again placed in peril of his life; he was threatened and tempted and slandered to the people, but all to no avail. His mother did her best to shield him from his enemies, but when she found that her care was not enough she trusted to his own remarkable judgment and courage. These never failed either the boy or his mother. As time passed it grew more and more clear that Peter was as strong as his poor stepbrother Ivan was weak, and in order to satisfy the people the younger boy was made joint-Czar with the elder. The real power in Russia then, however, was the Princess Sophia, Peter's half-sister, a bitter enemy of both the boy and his mother. She did her best to break her stepbrother's spirit, hoping that he might come to some untimely end, as so many of the royal family had already done. She knew that Ivan was simply a weak tool in her hands, and so bent all her energies to try and ruin the younger Czar by taking away all restraint from over him, and letting him indulge every pleasure and whim.
