Treaty of Haddington

The Treaty of Haddington was a treaty signed in 1548 between France and Scotland that promised Mary, Queen of Scots to Dauphin Francis in marriage in return for French assistance in the Siege of Haddington and subsequent French influence in Scotland. Mary, only six years old at the time, subsequently went to live in France, eventually marrying the Dauphin, while her regents ruled in her name in Scotland.

Parliament at the Abbey of St Mary, Haddington
The treaty was negotiated by the Earl of Arran, who earned a French duchy for himself in the process, with the French diplomats Henri Cleutin, Sieur d'Oysel and André de Montalembert, Sieur d'Essé. The agreement was made at a Convention or Parliament held at the Abbey of St Mary, Haddington. As a condition, Regent Arran had to send his son, James Hamilton, to France as security, as a "hostage".

Before Mary of Guise left the encampment at the Abbey, the English cannon fired and several in her company were killed. Scottish fortresses, including Blackness Castle, seem to have transferred to French keepership at this time. For a time, in the years 1548 and 1549, Scotland seems to have become almost a protectorate of Henry II of France.

John Knox was critical of the proceedings at Haddington, and later wrote that "French soldiers were the officers of arms in that Parliament".
