Known as the race of Diarmid, the clan Campbell was for centuries a most powerful influence in Argyll and the west of Scotland. In the 13th century Archibald Campbell obtained the Lordship of Lochow through his marriage with the daughter of the King’s Treasurer, and for a long period thereafter the Campbells of Lochow formed one of the chief branches of the clan.

Sir Colin, of Lochow, the progenitor of the Campbells of Argyll, was knighted in 1280, and from him the chiefs of the Argyll family received the designation, MacCailean Mor, retained by the Dukes of Argyll till the present day. His descendant Sir Duncan was created a peer by King James II in 1445, and Duncan’s grandson Colin was created Earl of Argyll in 1457. Archibald, his son, who was Lord High Chancellor, was killed at Flodden in 1513.

Archibald, 5th Earl, although a prominent Reformer, commanded the army of Queen Mary at the battle of Langside, while his brother Colin supported the young king. Archibald, 7th Earl, commanded the army which was defeated by the Earls of Huntly and Errol in 1594. His son was the leader of the Covenanters. He was created Marquis in 1641, but in spite of his loyalty was beheaded in 1661. His son Archibald was also beheaded for his part in the rebellion of Monmouth. Archibald, 10th Earl, returned with William of Orange, and by him was elevated to a Dukedom. John, 2nd Duke of Argyll, was created Duke of Greenwich in the peerage of the United Kingdom.
