The Huguenots, however, suspicious of the impending reaction at home and misreading the diplomacy of France in Switzerland, grew more and more fearful and began to turn their eyes again toward the prince of Condé as a leader. But fortune and the craft of Catherine had lured the prince away from his own; he had become a broken reed, dangerous to lean upon. In July, 1564, Eleanor de Roye, the brave princess of Condé, died.[858] The Guises and the queen mother, who were now in co-operation,[859] at once began to practice to lure Condé away forever from his party, and the former at the same time, in order to make the alliance between France and Scotland more firm, conceived the idea of marrying the prince of Condé to Mary Queen of Scots.[860] As another possibility the Guises cherished the hope of marrying their niece to Charles IX and thus recovering the ascendency they had enjoyed under Francis II.[861] The corollary of such a plan was the reduction of the Protestants of France. To these ideas Philip II, was stoutly opposed, though he concealed his opposition thereto; Mary was too valuable for his projects to be suffered to become a tool of the Guises. Their purposes were limited to France; his purposes embraced Christendom.[862] In 1575 the Venetian ambassador wrote, à propos of one of the courtships of Queen Elizabeth: “Princes are wont to avail themselves of matrimonial negotiations in many ways.”[863] These words sagely summarize the efforts of much of the diplomacy of the sixteenth century. By a singular combination of events and lineages, Mary Stuart was necessarily almost the cornerstone of the universal monarchy Philip II dreamed of forming in Europe; her possession of the Scottish crown, her claims to England, her relationship with the Guises, united with the religion she professed, made the furtherance of her power the most practicable means to that end. Whether Mary’s future husband were Don Carlos or the Austrian archduke was a matter of detail in Philip’s plan—the end remained constant. Mary Stuart was of too much value to Philip II’s political designs to risk such a marriage as the Guises contemplated.[864] Her hand might be disposed elsewhere with greater advantage.
