In the year 1503, Ivan III. lost his spouse, the Greek princess Sophia. Her death affected the aged monarch deeply, and seriously impaired his health. Twenty-five years had now elapsed since he received the young and beautiful princess as his bride, and during all these tumultuous years her genius and attractions had been the most brilliant ornament of his court. The infirmities of age pressed heavily upon the king, and it was manifest that his days could not much longer be prolonged. With much ceremony, in the presence of his lords, he dictated his will, declaring his oldest son Vassili to be his successor as monarch, and assigning to all his younger children rich possessions. The passion for the aggrandizement of Russia still glowed strongly in his bosom even in the hour of death. Vassili, though twenty-five years of age, was as yet unmarried. He decided to select his spouse from the daughters of the Russian nobles, and fifteen hundred of the most beautiful belles of the kingdom were brought to the court that the prince, from among them, might make his selection. The choice fell upon a maiden of exquisite beauty, of Tartar descent. Her father was an officer in the army, a son of one of the chiefs of the horde. The marriage was immediately consummated, and all Moscow was in a blaze of illumination, rejoicing over the nuptials of the heir to the crown. The decay of the aged monarch, however, advanced, day by day. His death, at last, was quite sudden, in the night of the 27th of October, 1505, at the age of sixty-six years and nine months, and at the close of a reign of forty three years and a half.
