The lapse of a few years, however, after this time, made a total change in Charles's position and prospects. His health improved, and his constitution began to be confirmed and established. When he was about twelve years of age, too, his brother Henry died. This circumstance made an entire change in all his prospects of life. The eyes of the whole kingdom, and, in fact, of all Europe, were now upon him as the future sovereign of England. His sister Elizabeth, who was a few years older than himself, was, about this time, married to a German prince, with great pomp and ceremony, young Charles acting the part of brideman. In consequence of his new position as heir-apparent to the throne, he was advanced to new honors, and had new titles conferred upon him, until at last, when he was sixteen years of age, he was made Prince of Wales, and certain revenues were appropriated to support a court for him, that he might be surrounded with external circumstances and insignia of rank and power, corresponding with his prospective greatness. In the mean time his health and strength rapidly improved, and with the improvement came a taste for manly and athletic sports, and the attainment of excellence in them. He gradually acquired great skill in all the exploits and performances of the young men of those days, such as shooting, riding, vaulting, and tilting at tournaments. From being a weak, sickly, and almost helpless child, he became, at twenty, an active, athletic young man, full of life and spirit, and ready for any romantic enterprise. In fact, when he was twenty-three years old, he embarked in a romantic enterprise which attracted the attention of all the world. This enterprise will presently be described. There was at this time, in the court of King James, a man who became very famous afterward as a favorite and follower of Charles. He is known in history under the name of the Duke of Buckingham. His name was originally George Villiers. He was a very handsome young man, and he seems to have attracted King James's attention at first on this account. James found him a convenient attendant, and made him, at last, his principal favorite. He raised him to a high rank, and conferred upon him, among other titles, that of Duke of Buckingham. The other persons about the court were very envious and jealous of his influence and power; but they were obliged to submit to it. He lived in great state and splendor, and for many years was looked up to by the whole kingdom as one of the greatest personages in the realm. We shall learn hereafter how he came to his end.
