The end of the MacDonald Lords came in 1493 when MacDonald II had his ancestral homeland, estates, and titles seized by King James IV of Scotland. Since that time, the MacDonald Clan has contested the right of James IV to the Lordship of the Isles and uprisings and rebellions against the Scottish Monarch were common. More recently, the Lordship of the Isles has been held by the Duke of Rothesay, the eldest son and heir apparent of the King of Scotland, a title which, since the creation of the Kingdom of Great Britain, is borne by the Prince of Wales. Thus Prince Charles is the current Lord of the Isles.
The arms adopted by the Lord of the Isles varied over time, but the blazon given and illustrated in the "Armorial of Sir David Lindsay of the Mount" (1542) is: Or, an eagle displayed gules beaked and armed sable overall a lymphad sable.
