During the fourteen years which followed his victory of Bannockburn, King Robert was consolidating his kingdom. He had obtained recognition even in the Western Highlands and Islands, and the sentiment of the whole nation had gathered around him. The force of this sentiment is apparent in connection with ecclesiastical difficulties. When Pope John XXII attempted to make peace in 1317 and refused to acknowledge the Bruce as king, the papal envoys were driven from the kingdom. For this the country was placed under the papal ban, and when, in 1324, the pope offered both to acknowledge King Robert and to remove the excommunication, on condition that Berwick should be restored to the English, the Scots refused to comply with his condition. A small rebellion in 1320 had been firmly repressed by king and Parliament. The birth of a son to King Robert, on the 5th March, 1323-24, had given security to the dynasty, and, at the great Parliament which met at Cambuskenneth in 1326, at which Scottish burghs were, for the first time, represented, the clergy, the barons, and the people took an oath of allegiance to the little Prince David, and, should his heirs fail, to Robert, the son of Bruce's daughter, Marjorie, and her husband, Robert, the High Steward of Scotland. The same Parliament put the financial position of the monarch on a satisfactory footing by granting him a tenth penny of all rents. The deposition and murder of Edward II created a situation of which the King of Scots could not fail to take advantage. The truce was broken in the summer of 1327 by an expedition into England, conducted by Douglas and Randolph, and the hardiness of the Scottish soldiery surprised the English and warned them that it was impossible to prolong the contest in the present condition of the two countries. The regents for the young Edward III resolved to come to terms with Bruce. The treaty of Northampton, dated 17th March, 1327-28, is still preserved in Edinburgh. It acknowledged the complete independence of Scotland and the royal dignity of King Robert. It promised the restoration of all the symbols of Scottish independence which Edward I had removed, and it arranged a marriage between Prince David, the heir to the Scottish throne, and Joanna, the sister of the young king of England. A marriage ceremony between the two children was solemnized in the following May, but the Stone of Fate was never removed from Westminster, owing, it is said, to the opposition of the abbot. The succession of James VI to the throne of England, nearly three centuries later, was accepted as the fulfilment of the prophecy attached to the Coronation Stone, "Lapis ille grandis": "Ni fallat fatam, Scoti, quocunque locatum, Invenient lapidem, regnare tenentur ibidem".
