Edward and Elizabeth had now been married some time, but they had no son, and, of course, no heir, for daughters in those days did not inherit the English crown. Of course, Clarence, Edward's second brother, was the next heir. This increased the jealousy which the two brothers felt toward each other, and tended very much to drive Clarence away from Edward, and to increase the intimacy between Clarence and Warwick. At length, in 1468, it was announced that a marriage was in contemplation between Clarence and Isabella, the Earl of Warwick's oldest daughter. Edward and Queen Elizabeth were very much displeased and very much alarmed when they heard of this plan. If carried into effect, it would bind Clarence and the Warwick influence together in indissoluble bonds, and make their power much more formidable than ever before. Every body would say when the marriage was concluded, "Now, in case Edward should die, which event may happen at any time, the earl's daughter will be queen, and then the earl will have a greater influence than ever in the disposition of offices and honors. It behooves us, therefore, to make friends with him in season, so as to secure his good-will in advance, before he comes into power." King Edward and his queen, seeing how much this match was likely at once to increase the earl's importance, did every thing in their power to prevent it. But they could not succeed. The earl was determined that Clarence and his daughter should be married. The opposition was, however, so strong at court that the marriage could not be celebrated at London; so the ceremony was performed at Calais, which city was at that time under the earl's special command. The king and queen remained at London, and made no attempt to conceal their vexation and chagrin. CHAPTER VI.
