A hero of the Royalist Cause in Scotland, James Graham the 1st Marquess of Montrose or "The Great Montrose" as he is still known to the Highlanders today united several of the Highland clans and along with Alasdair Mac Colla's Irishmen succeeded in defeating the Parliamentarian-aligned Scots Covenanters in a series of impressive victories during the War of the Three Kingdoms.
