Treaty of Northampton

Prior to the Treaty of Northampton, Edward II claimed he adhered to a truce, but he allowed English privateers to attack Flemish vessels trading with Scotland. For example, privateers seized the Flemish vessel Pelarym worth �2,000. All the Scots on board were massacred. Bruce demanded justice, but in vain. Consequently, Robert I renewed the Auld Alliance between Scotland and France which was concluded 26 April 1326, at Corbeil.

In 1327, the Scots invaded northern England and defeated the English at Stanhope and Weardale. Soon afterwards, the Scots invaded Ulster in Ireland. Isabella and Earl Mortimer of March could not raise a force on such short notice and agreed to make peace on Bruce's terms. In May 1328 Isabel and Mortimer agreed in the treaty that they in the name of young Edward III "renounced all pretensions to sovereignty" to Scotland; and Joanna (six years of age), sister of Edward III, was promised in marriage to David (four years of age), son of Robert Bruce. In the quitclaim of Edward III of 1328, one can see the treaty of Northampton mentioned: The Scottish borders set by Alexander III "shall remain for ever to the eminent prince Lord Robert, by the grace of God the illustrious king of Scots, our ally and dearest friend, and to his heirs and successors, divided in all things from the realm of England, entire, free, and quit, without any subjection, servitude, claim, or demand."

Also, as part of the treaty, Edward III agreed to return the Stone of Destiny to Scotland. However, this was never done.
