James III (10 July 1451 – 11 June 1488) was King of Scots from 1460 to 1488. James was an unpopular and ineffective monarch owing to an unwillingness to administer justice fairly, a policy of pursuing alliance with the Kingdom of England, and a disastrous relationship with nearly all his extended family. However, it was through his marriage to Margaret of Denmark that the Orkney and Shetland islands became Scottish.
