The 'Auld Alliance' originated as an offensive and defensive treaty made by John, King of Scots, and Philip IV of France, directed against Edward I of England, in 1295-6. Remarkably, this original treaty of Paris/Dunfermline was frequently renewed throughout the course of the next two-and-a-half centuries, becoming latterly a cornerstone of Scottish foreign policy. Combining narrative and analysis, this book covers the uncertain beginnings of the Alliance, moving on to the major military commitment of the Scots to the French side in the Hundred Years' War (1337-1453) with England, the subsequent settlement of Scots in France in the fifteenth century, the close naval and military links between James IV and Louis XII of France in the early sixteenth century, and the climax and end of the Alliance following the marriage of Francis II of France to Mary, Queen of Scots (1558).
