In 1290 King Edward I of England sent Walter de Huntercombe to take possession of Mann. It remained in English hands until 1313, when Robert Bruce took it after besieging Castle Rushen for five weeks. In 1314, it was retaken for the English by John Bacach of Argyll. In 1317, it was retaken for the Scots by Thomas Randolph, 1st Earl of Moray and Lord of the Isle of Man. It was held by the Scots until 1333. For some years thereafter control passed back and forth between the kingdoms until the English took it for the final time in 1346. The English Crown delegated its rule of the island to a series of lords and magnates. Tynwald passed laws concerning the government of the island in all respects and had control over its finances, but was subject to the approval of the Lord of Mann.
