Early in 1536 Queen Catharine died. Her heart had been broken by the conduct of the king and by separation from her daughter the Princess Mary. Time and again she had been commanded under threat of the severest punishment to accept the sentence of Cranmer's court, but both herself and the Princess refused steadfastly to subscribe to such a dishonourable verdict. After Catharine's death and merely to save her life Mary signed a document agreeing to the abolition of papal supremacy and the invalidity of her mother's marriage, though nobody attached any importance to a submission that was obtained in such circumstances. The death of Catharine was a great relief to Henry and Anne, more especially to the latter, who had some reason for believing that she herself had lost her hold on the affections of the king. Henry had already grown weary of the woman for whose sake he had put his lawful wife away and separated his kingdom from the Catholic Church, and the disappointment of his hopes for the birth of an heir to the throne confirmed his intention of ridding himself of a partner, who was regarded by his own subjects and the nations of Europe only as his concubine. She was arrested on a charge of misconduct with her brother and other gentlemen of the court, was tried before a body of the peers, and was put to death at Tyburn (17th May, 1536). Cranmer, who in his heart was convinced of her innocence, promptly held a court and pronounced her marriage with Henry null and void. On the very day of her execution he issued a license for the king to marry Jane Seymour, one of Anne's maids of honour, and before the end of the month the marriage was celebrated. In June Parliament confirmed Cranmer's sentence by declaring the invalidity of Henry's previous marriages, and the illegitimacy of Mary and Elizabeth, and by fixing the succession on the heirs of the king and Jane Seymour. Furthermore, in case there might be no children it empowered the king to determine by his will who should succeed. The object of this was to enable him to appoint as his heir his bastard son, the Duke of Richmond, but this intention was frustrated by the death of the Duke (July 1537).
