Ignoring legendary origins, the MacKenzies claim to be descended from Colin, progenitor of the Earls of Ross. He died in 1278 and was succeeded by his son Kenneth, whose son was also named Kenneth, In 1362 Murdoch, son of Kenneth, received from David II, the lands of Kintail.
In 1491 the MacKenzies defeated the MacDonalds in a fierce battle known as Blair-na-park. The clan supported James IV. At Flodden where their chief was captured by the English, and at the Battle of Pinkie the MacKenzies fought for James V. Colin, 11th chief, fought in the army of Queen Mary at Langside. Kenneth, 12th chief, in 1607 received a charter of the lands of Lochalsh and Lochcarron, and it is said that at this time all the lands from Ardnamurchan to Strathnaver were in the possession of the MacKenzies or their vassals.
Kenneth was created Lord MacKenzie of Kintail in 1609. Colin, 2nd Lord, was created Earl of Seaforth by James VI. in 1623, and was Secretary of State in Scotland to Charles II. Kenneth, 4th Earl, was nominated a Knight of the Thistle by James VII, whom he followed to France. William, 5th Earl, joined the Earl of Mar in 1715, was at Sheriffmuir, and later escaped to France. He was detained and his estates forfeited. He returned to Ross-shire and was wounded at the Battle of Glensheil in 1719. In 1726 he was pardoned by George I, and died in Lewis in 1740.
Kenneth, his grandson, repurchased the forfeited estates and in 1771 was restored to the Earldom of Seaforth. Francis Humbertson MacKenzie, who had succeeded to the estates of Seaforth and Humbertson, was created a British peer in 1797 by the title Lord Seaforth, Baron MacKenzie of Kintail. He died in 1815, his four sons having predeceased him, and his eldest daughter married J. A. Stewart of Glasserton who assumed the name Stewart MacKenzie of Seaforth.
The Earldom of Cromartie and several baronetcies are held by branches of the clan.
