The surname Campbell, most probably derived from the Gaelic cam-beul (twisted mouth), is one of the oldest in the Highland, and a crown charter of 1368 acknowledges Duncan MacDuihbne as founder of the Campbells, who were established as Lords of Loch Awe. The founder of the Argyll line was Cailean Mór (d. 1294), whose descendant, Colin Campbell (d. 1493), 1st Earl of Argyll, married Isabel Stewart of Lorne. To this day the eldes son of the family has borne the title of Marquis of Lorne, and the marriage in 1871 of the Marquis, later 9th Duke of Argyll, to HRH Princess Louise, fourth daughter of Queen Victoria, is recalled by the two tartans bearing their names.

Throughout the fifteenth century the Campbells gave steady support to the Crown in an area where royal influence was under severe pressure, first from the rival Crown of Norway and then from the descendants of Somerled, former Lord of the Isles, with the eventual emergence of the Crown's most powerful rival in the MacDonald Lordship of the Isles. The Lordship of the Isls was broken by the Crown by the end of the fifteenth century, leaving the Campbells the main power in the area. Thereafter they continued to act as the chief instrument of central authority in the region. This long struggle for supremacy, and with it, the headship of the Gael, may be said to be the real cause for the ancient enmity between the Campbells and the MacDonalds.

Campbell support for central government brought rewards. In 1607 Archibald, seventh Earl of Argyll, was granted former MacDonald lands in Kintyre, while in 1615 Campbell of Cawdor was allowed to purchase Islay and most of Jura which had previously belonged to the Macleans of Duart.

Sir John Campbell (1635-1716), 11th Laird of Glenorchy, was created Earl of Breadalbane in 1681. Described as being "cunning as a fox, wise as a serpent, and supple as an eel... [who] knew neither honour nor religion but where they are mixed with interest", he was involved in the scheming which resulted in the Massacre of Glencoe, but no evidence of his guilt could be produced. His line was founded by the colourful crusader "Black" Colin Campbell (d. 1498), who received Glenorchy in 1432 from his father, Sir Duncan Campbell, who had ejected the MacGregors from the lands. The commander who actually carried out the infamous Massacre of the MacIan MacDonald's of Glencoe was a Campbell Chieftain of Glenlyon. The founder of the Cawdor branch, another Sir John Campbell (d. 1546). An orphan who had inherited her father's title of Thane of Cawdor, she was kidnapped in 1499 by Campbell’s father, Archibald (d. 1513), 2nd Earl of Argyll, and married to his son in 1510. The Campbells of Loudoun are descended from Sir Duncan Campbell, second of the first MacCailean Mór, who married a Crauford of Loudoun. The Earldom of Loudoun, created for John Campbell (1598-1663), politician, has since the eighteenth century descended through the female line.

Arguably the most famous Campbell of them all, Sir Colin Campbell (1792-1863), commander of the Highland Brigade at Balaclava, Commander-in-Chief during the Indian Mutiny, the hero of Lucknow and Cawnpore, was not strictly a Campbell at all, being born Colin MacLiver, son of a Glasgow carpenter. His mother was a Campbell, though, and when her brother, Colonel John Campbell, took the fifteen-year-old boy to be interviewed for the Army by the Duke of York, the Duke wrote his name down as Campbell. And Campbell it remained.

The Clan Campbell is now organized world-wide in several associations and societies connected to the Clan Campbell Federation. The current Chief is the twelfth Duke of Argyll and twenty-sixth Chief. Inveraray Castle is still his family home.

MacDonald of Clan Ranald

John MacDonald, the Lord of the Isles, married Amy MacRuari and she bore him three sons.  The youngest was Ranald and from him descended the Houses of Clanranald and Glengarry.

The MacDonald's of Clan Ranald take their name from Ranald, the son of John of Islay, 1st Lord of the Isles and Amy Macruari. Ranald was the obvious heir to chiefship of Clan Donald but However, when the succession occured it was Donald, Ranald's younger half-brother who became chief. Ranald however did receive the territories of Moydart, Lochaber and Arisaig.

The next chief was Alan, eldest of Ranald's five sons. Alan is the founder of the Glengarry MacDonald's. During the 1400's there were long running feuds between the various branches of Clan Donald. These culminated in 1544 with the battle of Blar-na-leine. The battle was between the supporters of Ranald, son of the fifth chief and his cousin John of Moidart who opposed him. On Ranald's side were the Frasers of Lovat and siding with John were the MacDonnells of Keppoch and the Clan Cameron. In the end the Frasers were defeated and John of Moidart became the chief of Clan Ranald.

Another remarkable chief succeeded to Clan Ranald in 1687. This was Alan who, after only three years as chief, led his Clan at Killicrankie in support of King James VII. He was forced into exile in France where he served in the French army for a short time. In September of 1715 he was one of the first to join the Jacobite cause. He was created Lord

Clanranald by the grateful James VII.

The Clan Ranald was also well represented in the '45 rebellion for which the chief was forced into exile once more in France. He was allowed to return in 1754. The chiefly line died out in 1944 at which time the chiefship passed to the descendants of Alexander MacDonald of Boisdale, a younger brother of the seventeenth chief.
