James V was destined for a French marriage by the
Treaty of Rouen of 1517, which aimed to secure the
Auld Alliance. Erskine travelled to France, Rome, and England regarding James's marriage, notionally to
Madeleine of Valois daughter of
Francis I of France Erskine was sent to France as a diplomat to contract this marriage in April 1530. He was joined in this commission with
John Stewart, Duke of Albany. However, at this time James V's advisors and the Duke of Albany hoped to gain political advantage by contracting the King's marriage to
Catherine de' Medici the young
Duchess of Urbino. On his way to Rome to meet Albany in December 1531 to further the Urbino marriage with
Pope Clement VI, Erskine was shipwrecked on the French coast. When Erskine arrived in Rome in the spring of 1531 he dined with the Spanish ambassador Mai, who may have been a fellow student at Pavia. Erskine's instructions may have included asking Albany to press Clement VI to allow James V to tax the church in Scotland. The historian Robert Kerr Hannay argued that the resultant 'tax of the three teinds' was part of the process of the formation of the College of Justice. The marriage plan changed, and in February 1533, two French ambassadors,
William du Bellay, sieur de Langes and Etienne de Laigue, sieur de Beauvais, who had just been in Scotland, told the Venetian ambassador in London that James was thinking of marrying
Christina of Denmark. Two years later, Erskine was in France with
David Beaton still trying to secure the King's marriage to Princess Madeleine. He had letters of recommendation from James V to
Eleanor of France, the
Queen of Navarre, Madame Aubigny and Robert Stuart, sieur d'Aubigny, the Chancellor
Antoine Duprat Cardinal of Sens, the Admiral
Philippe de Chabot, the Grand Master
Anne de Montmorency, and the French Secretary Jean le Breton,
sieur de Villandry. Erskine and Beaton were instructed to arrange for Madeleine to come to Scotland next summer, when she was fourteen, or in July 1535. Initially, Francis I organised a substitute bride: Erskine was at
Cremieu on 6 March 1536 when the contract was made for James V to marry
Mary of Bourbon, daughter of the
Duke of Vendôme. ==Further reading==
