The Earldom of Mar is one of the oldest and most historically significant of all the Scottish earldoms, its origins reaching back into the Pictish and early medieval world of north-eastern Scotland long before the clan system took the form we recognise today. Mar, the ancient mormaerdom centred on upper Donside and the surrounding Aberdeenshire uplands, was a territorial power of the first order in Scotland's formative centuries, and the family most closely associated with it — recorded variously as Mar, Mair, or Mac an Mhaoir — left a mark on the history of the north-east that can still be traced in its castles, its documents, and its landscape. The story of Clan Mar is in many respects the story of a region as much as a family, and Kildrummy Castle — the great fortress that served as the principal seat of the Mar earls — stands as its most enduring monument.
What Are the Origins of the Mar Name and Earldom?
The name Mar is territorial in origin, derived from the ancient district of Mar in Aberdeenshire, a broad upland region of the north-east encompassing the valleys of the Don and Dee and the high ground between them. The earldom is among the most ancient in Scotland, predating the Norman settlement that transformed the Lowlands in the twelfth century, and the mormaers — the great regional lords of early medieval Scotland — who held it were among the most powerful men in the kingdom. The associated surname Mair, or Mac an Mhaoir in Gaelic, means son of the mair or son of the steward, indicating an administrative or judicial role of considerable importance in the old Gaelic social order. The mair was a legal officer responsible for enforcing the decisions of courts, managing the affairs of an estate, or carrying out the instructions of a lord — a position of real authority and trust. The Mar family and the Mair name thus represent two related but distinct dimensions of the same north-eastern tradition: the great territorial lords of the earldom on one hand, and the professional administrative class that served the lords and the law on the other.
What Lands and Castles Were Associated with the Earldom of Mar?
The heartland of Mar was upper Donside and the district around Strathdon in Aberdeenshire, a landscape of river valleys cutting through moorland and hill country toward the high ground of the Grampian range. Kildrummy Castle, whose dramatic ruins stand in a hollow of the Don valley near the village of Kildrummy, was the principal seat of the Mar earls and one of the most important castles in medieval Scotland. Built in the thirteenth century, Kildrummy was a sophisticated and extensive fortification by the standards of its time, with a plan that showed clear familiarity with the most advanced castle-building practices of contemporary Europe. Its great hall, chapel, and concentric defences made it a fortress capable of withstanding prolonged siege, and its position in upper Donside gave its holders a commanding presence over the routes between the Lowlands and the Highland interior. The castle was heavily involved in the Wars of Scottish Independence in the early fourteenth century, twice besieged and on one occasion taken by treachery — a blacksmith within the castle was bribed to set fire to the grain stores, causing the garrison to surrender. The ruins that survive today are extensive enough to give a vivid impression of the castle at its height, and Kildrummy is regarded as one of the finest examples of thirteenth-century Scottish castle architecture in the country. The wider northeast world the Mar earls inhabited was shared with powerful neighbours including the Clan Gordon, whose own Aberdeenshire territories and earldom of Huntly eventually came to dominate much of the same landscape.
What Was the Clan Motto and What Did It Mean?
The motto associated with the Mar name is Pans Plus, a phrase rendered in French rather than the Latin more common in Scottish heraldry, translating as think more or think further. It is a motto of intellectual deliberation — a counsel to reflect carefully before acting, to consider consequences and weigh alternatives rather than rushing to judgment or action. For a family whose history included some of the most consequential political decisions in Scottish history, a motto that valued careful thought over impulsive action carried genuine meaning. The two wings emerging from a chapeau, or cap of dignity, that appear in the clan’s heraldic tradition reinforce this image with a suggestion of swiftness and elevated purpose — the ability to act decisively once thought has identified the right course. Together, motto and crest present a family that aspired to the combination of wisdom and capability that the best governance requires.
Who Were the Notable Figures Associated with the Earldom of Mar?
The history of Mar is populated by figures of considerable historical weight. Gartnait, one of the early mormaers of Mar, appears in records from the eleventh and twelfth centuries as a significant power in the north-east. The medieval earls of Mar were among the most important lords in Scotland, their earldom giving them a territorial base and a military capacity that placed them at the centre of the great conflicts of the thirteenth and fourteenth centuries. Donald, Earl of Mar, a nephew of Robert the Bruce, served as Guardian of Scotland during the minority of David II and was killed at the Battle of Dupplin Moor in 1332, one of the most significant military defeats of the period. In the Jacobite era, John Erskine, the sixth or eleventh Earl of Mar depending on which reckoning of the title is followed, led the Jacobite rising of 1715 — the most substantial of all the Jacobite risings in terms of the forces involved. Mar raised his standard at Braemar in September 1715, declaring for the Old Pretender and drawing a substantial Highland and Lowland force to his cause. His military campaign, however, was fatally undermined by his own indecisive generalship, and the Battle of Sheriffmuir in November 1715 — a confused engagement fought to no clear conclusion — effectively ended the rising’s momentum. Mar fled to France, dying in exile in 1732, and his title was forfeited. The abortive rising of 1715 is sometimes called the Mar Rising or the Fifteen in his honour, and his failure is one of the more melancholy episodes in Jacobite history. The northeast traditions of Mar connect also with the story of Clan Keith, whose hereditary Marischalship of Scotland placed them in the same institutional world as the Mar earls across several centuries of north-eastern Scottish history.
How Did Mar Feature in the Wars of Scottish Independence?
The Earldom of Mar was deeply involved in the Wars of Scottish Independence that consumed Scotland from 1296 onward. Kildrummy Castle was twice besieged during this period. In 1306 it sheltered the family of Robert the Bruce while he was fighting to assert his claim to the Scottish throne, and the castle’s fall to the English that year, achieved by the treachery of the blacksmith Osbourne who burned the grain in exchange for as much gold as could be packed into his mouth, was a serious blow to the Bruce cause. The castle was subsequently held by the English before reverting to Scottish control as the tide of the war turned after Bannockburn in 1314. The involvement of the Mar earls and their castle in these events placed the earldom at the heart of the most consequential military and political struggle in Scottish history, and the stories that attached to Kildrummy during the wars gave it a legendary quality in the national memory that its physical ruins continue to evoke.
How Is the Mar Name Remembered Today?
The Earldom of Mar has had a complex legal and historical existence since the forfeiture of 1716, with competing claims to the title generating litigation that has continued into modern times. The name Mar itself, and its variant Mair, is carried by descendants across Scotland and the wider diaspora, and those researching either form of the name will find the Aberdeenshire parish records and the legal records of the earldom among their most productive sources. Kildrummy Castle, now maintained as a scheduled monument and open to visitors, provides the most dramatic physical connection to the Mar story, its substantial ruins in the Don valley remaining among the most evocative castle sites in Aberdeenshire. The motto Pans Plus — think more — endures as the most memorable legacy of the Mar heraldic tradition: a quiet counsel to deliberation in a world that rarely slows down enough to take it.
