It seems that Edward was not satisfied, and felt that, while his brother was king, he could not achieve what he deserved in Scotland. With Robert's full backing, he embarked on an expedition to Ireland. He seems to have landed in Ulster at the end of May 1315, with the support of Ulster nobles, who had close links with Scotland; but then forced them to acknowledge him as king of Ireland, implying an intention to conquer the whole island. He proceeded to the south, ravaging as usual as he went; but did not find the support he expected. By October 1316, he wrote to the Welsh suggesting that he should join them in an attempt to expel the English from Wales, and that he should become prince of Wales as well as king of Ireland! There was so little reality in all this that in 1317, his brother had to come briefly to his aid in Ireland, but with little success. Edward's position as king was impossible to sustain; and in October 1318 he was killed in battle at Faughart, near Dundalk.
Edward Bruce, d. 1318, Scottish king of Ireland, brother of Robert I of Scotland. He aided his brother in the war for independence from England and in 1315 was declared heir to Robert's throne. With Robert's approval he then invaded Ulster, to which he had some hereditary claim. He was crowned king of Ireland in 1316 and found many Irish allies against the Anglo-Irish rulers. However, he failed to consolidate his gains and was killed in battle in 1318.
