    The Constant Princess
    Philippa Gregory

    Katherine of Aragon (also known as Catalina) has known her destiny since childhood: to wed Prince Arthur of England. The daughter of Queen Isabella and King Ferdinand of Spain, 16-year-old Katherine leaves behind her beloved home to forge a new life in a foreign land and take her place as Princess of Wales and, ultimately, Queen of England.
    To Katherine's surprise, her marriage to Arthur is a passionate love match as well as a political union. As the Prince and Princess of Wales, they eagerly plan for their future reign -- until tragedy strikes five months into their marriage. Arthur falls ill, and before he dies the young prince extracts a vow from his wife. She is to marry his brother, Harry, and become Queen of England. She is to rule England in Arthur's stead, fulfilling their dreams and her destiny. But to take the throne, Katherine must deny her true love and tell the world that she and Arthur never consummated their marriage.
    The Constant Princess is the story of a young girl who was raised to be a queen, the lengths to which she goes to fulfill a deathbed promise, and the crucial lie that changed the course of history.

    Questions & Topics for Discussion
    1. The novel opens in Granada, Spain, as five-year-old Catalina witnesses her parents, Isabella and Ferdinand, conquer the last stronghold of the Moors in Spain. What does this chapter reveal about Catalina, as well as about her mother and their relationship? In what ways did having this portrait of Catalina as a child help you better understand some of her later decisions and motivations?

    2. "I did not expect [Arthur] to be so handsome! He is so fair and slight, he is like a page boy from one of the old romances" (34). Why does Catalina's romantic view of Arthur disintegrate after their wedding? How does their journey to Ludlow Castle -- and their first evening there when Catalina acquaints Arthur with some of the customs of her homeland -- become the turning point in their relationship?

    3. On his deathbed, Arthur asks Catalina to marry his brother and rule England in his place. What prompts Arthur to ask this of Catalina? Does Catalina promise Arthur for his sake or for her own? How does she justify telling the lie that makes it possible for her to wed Harry?

    4. After Arthur's death, Lady Margaret Pole suggests that perhaps God wills that Catalina accept her fate as Dowager Princess. "He does not," Catalina responds. "I shall insist on what is mine. I know what is my duty and what I have to do" (164). Why is Catalina so certain that it's God's will she become Queen of England? Is this conviction a result of her faith, her upbringing, or something else?

    5. How is Catalina used as a political pawn by her parents? What is your opinion of Isabella of Spain, both as a monarch and as a mother? How about King Ferdinand?

    6. While at Ludlow Castle, Arthur and Catalina make plans for their future reign as king and queen of England. "You are a tactician," Arthur tells Catalina during one of their conversations. "I wish to God I had your childhood and knew the things you know" (129). What tactics did Catalina learn as the child of two powerful monarchs? How does she put these skills to use in her rise to the throne?

    7. When it's realized that Catalina is not pregnant with Arthur's child, her mother sends an emissary to escort her home to Spain. Why does Catalina, who was raised knowing it's a princess's duty to obey her parents, defy her mother and remain in England? Why is it so important to her that she not return to Spain? Are her reasons more political or personal?

    8. Why does Catalina first accept King Henry VII's marriage proposal and then refuse him? The king vows that Catalina "will regret the day she tried to lead me on as if I were a lovesick boy" (230) and exacts revenge by a false betrothal to Harry. When does Catalina realize that she is being used as a pawn in the king's scheme? Does she have any recourse other than to remain a "constant princess" for six years?

    9. On his deathbed, King Henry tells Harry that the young man is free to marry whomever he chooses. Why does Harry decide to honor his betrothal and marry Catalina? What actions does Catalina take to make Harry want to marry her? What is the significance of Catalina changing her name to Katherine when she becomes queen?

    10. How does Katherine usurp power from the king's grandmother, Margaret Beaufort, and then, "slowly but surely," draw the "management of the entertainments, then of the household, then of the king's business, then of the kingdom, into her hands" (286)? How much control does Katherine eventually come to have over the kingdom?

    11. On two occasions Katherine consults in secret with Yusuf, a Moorish physician. What does she come to realize about Yusuf during their clandestine meetings? How about the Moors in general and her mother's treatment of them in Spain? How does this realization impact her later decision not to lay waste to Scottish lands after she defeats them in battle?

    12. Describe Katherine and Henry's marriage. How is the age difference (Henry is six years Katherine's junior) a factor? How does Katherine's first confinement -- for what turns out to be a false pregnancy -- change their relationship and her standing in the court?

    13. "I have no tears for the husband who is going away because he has left me with everything that I have ever wanted (374)," Katherine says when Henry sets sail to face combat in France. In what ways is this a triumphal moment for Katherine? Later, on the brink of going to war with Scotland, why does Katherine refer to the impending battle as "the moment of my destiny" (375)?

    14. Sixteen years after her historic victory over the Scots, Katherine is summoned to face another battle -- a fight against the dissolution of her marriage during a papal legate sitting. Why, even under this intense scrutiny, does Katherine remain steadfast in her lie that she was a virgin when she married Henry? What final impression does this scene give you of Katherine of Aragon?
