Sheep & the Wool Economy

The expansion of sheep farming across the Highlands in the 18th and 19th centuries is sometimes presented as simply a change in land use, separate from the human story of the Highland Clearances. This separation is not honest history. Sheep farming — specifically the introduction of large-scale commercial sheep breeds such as the Cheviot — was a primary economic driver of the Clearances: landowners evicted tenant communities from glens and straths specifically to replace subsistence farming with far more profitable sheep grazing. The wool and mutton economy's growth and the Clearances' human cost are two sides of the same historical process, not separate topics.

The causal link between sheep farming expansion and the Highland Clearances is well established in historical scholarship, supported by estate records, contemporary accounts, and extensive subsequent historical research; this article treats it as settled fact, not a matter of balance between equally weighted positions. Where genuine historiographical debate exists, it concerns emphasis and interpretation — for example, how much weight to give to landowners' stated economic rationale for clearance versus the human cost and coercion involved — and this article notes that specific point as disputed, while being clear that the disputed element is the moral/interpretive framing, not the basic historical fact that sheep farming replaced displaced communities on cleared land.

Origins: Why Sheep Farming Expanded

The expansion of large-scale sheep farming across the Scottish Highlands from the later 18th century must be understood within the context of the Highlands' changing political and economic structure following the failure of the Jacobite risings and the subsequent dismantling of traditional clan-based social and military organisation. As the old social contract that had bound clan chiefs to their tenants weakened, many Highland landowners increasingly came to view their estates primarily as commercial assets to be managed for maximum financial return, rather than as the basis of a reciprocal social relationship with resident tenant communities.

Within this context, sheep farming offered landowners a compelling economic proposition. Hardy breeds such as the Cheviot could be run extensively across upland grazing with relatively little labour compared with the dense patchwork of small tenant farms that had previously occupied the same land, while producing wool and mutton for growing industrial and urban markets. The profitability calculation was straightforward and widely documented in estate correspondence and records of the period: large-scale sheep farming could generate substantially higher rental and sale income from a given area of land than traditional subsistence tenant agriculture, particularly once Lowland and English wool markets expanded demand.

The Clearances: Sheep Farming as Primary Driver

It is essential to state directly, rather than soften, what this economic logic meant in practice: landowners across large areas of the Highlands evicted tenant communities — sometimes with notice and alternative (though often inferior) land offered, and sometimes through direct force, including the burning of homes — specifically to clear land for sheep farming. This is the Highland Clearances, one of the defining and most painful episodes in Scottish social history, and sheep farming's profitability was not an incidental backdrop to these evictions but their primary economic driver. Areas such as Sutherland saw some of the most extensive and historically notorious clearance activity, where entire communities were relocated — often to marginal coastal crofting townships poorly suited to supporting the displaced population — or left with little practical option but emigration.

The human cost of this process was severe and well documented: communities that had occupied glens and straths for generations were displaced from land that held deep social, cultural, and economic meaning, often with inadequate compensation or support, and the disruption contributed significantly to the depopulation of large areas of the Highlands that continues to shape the region's demographic and cultural landscape today. Some historical accounts sympathetic to landowners have framed the Clearances as an unfortunate but ultimately rational modernisation of an economically unsustainable traditional system; this framing is seriously disputed by the great majority of social historians and by the extensive oral history and testimony of affected communities, which emphasise coercion, trauma, and the prioritisation of landowner profit over tenant welfare. This article treats that landowner-sympathetic framing as a contested historical position, not as an equally weighted alternative to the documented record of displacement and its human cost.

Peak Scale and the Wool Economy's Industrial Connections

By the mid-19th century, sheep farming had reshaped vast areas of the Highland landscape, with large commercial sheep estates replacing the dense patterns of small tenant farming that had characterised much of the region previously. This transformation fed into a broader Scottish and British wool economy, in which raw wool from Highland (and other Scottish) sheep farming fed into textile manufacturing, most notably the long-established and increasingly industrialised woollen textile industry of the Scottish Borders, where towns including those along the Tweed became major centres of woollen cloth and (later) tweed manufacturing. This Borders textile industry, while historically and economically connected to Highland wool production, developed its own distinct industrial character, manufacturing processes, and labour history, and is treated as a separate subject in this series' dedicated Borders Wool/Tweed card rather than duplicated here — this article focuses specifically on the Highland sheep farming expansion and its direct relationship to the Clearances, while acknowledging the wool trade's broader economic connection to Borders manufacturing.

Present-Day Legacy

Sheep farming remains part of the Highland agricultural economy today, though at a significantly reduced scale compared with its 19th-century peak, and in some areas it was itself later superseded by a further shift toward deer estates and sporting land use, reflecting the continuing evolution of Highland land economics driven by changing profitability calculations — a pattern that echoes, in a different form, the same commercial logic that drove the original Clearances. The Highland Clearances themselves are now widely recognised and commemorated as a defining, traumatic episode in Scottish history, studied extensively in academic history, remembered in Highland communities and the Scottish diaspora (particularly in areas of significant Highland emigration such as parts of Canada, the United States, and Australia), and increasingly addressed through heritage interpretation, memorials, and public historical reckoning. An honest account of Scotland's sheep and wool economy cannot separate the industry's genuine commercial success from the human displacement that made much of that success possible.

The spread of sheep farming, from the Borders to Sutherland

Commercial sheep farming came to the Highlands from the south. The geographer Robert Dodgshon notes that Buccleuch estate figures from the Southern Uplands in the early 1680s already show farms with flocks of over 500 sheep, some over 1,000, and about half of all farms held by single tenants. After the bad harvests and bankruptcies of the 1680s, Edinburgh lawyers bought farms there and reorganised them as specialist sheep units.

The first Highland clearances for sheep came in the 1750s in the southern Highlands, as the northward extension of that Border model. Many of the new sheep farmers were Borderers. John Campbell, who replaced four runrig tenants at Glenovoe in Dunbartonshire in 1754 and was reputed to be the first large-scale sheep farmer there, had farmed in Annandale. Not everyone believed in it: in 1775 the agricultural writer Andrew Wight predicted that those converting the Highlands to sheep would, "very probably after doing mischief to themselves", go back to black cattle. In the southern Highlands sheep farms stayed modest, some were first held jointly by former tenants, and many kept a herd of about 20 cattle into the 1840s.

In the north and north-west, clearances came mainly after 1800 and on a far larger scale. "Several thousand" people were cleared from the interior straths of Sutherland, including Strathnaver, in 1814–16, and 3,331 from Kildonan, Lairg and Rogart in 1819. The resulting holdings were vast: Donald and William Mackay built up more than 150,000 acres from a base at Melness, Greig of Tulloch was said to have "100 square miles under sheep", and Cameron of Corychoillie's holdings clipped 37,000 sheep a year. Each was divided into hirsels, each worked by a single shepherd, so that whole townships could be replaced by one shepherd and his family except at shearing time.

Sheep walks and emigration

established Emigrants themselves named sheep as a reason for leaving long before the great clearances. The historian Marjory Harper, in Adventurers and Exiles (2003), quotes the government's Register of Emigrants for a party of Argyll farmers and labourers who sailed for Wilmington, North Carolina, in September 1775. Those from Appin said that a third of their district, 33 of 100 merkland, had already been "turned into Sheep Walks", and they expected two-thirds to follow. In November 1818 Donald Logan of Rogart, who had emigrated to Nova Scotia and come home to help others go, told the government that minor tenants whose farms the proprietors found "more lucrative to lay under sheep" were being moved to unsuitable ground. In 1826–27 forty-four small farmers and labourers in Duirinish, Skye, petitioned for assisted passages because their farms had been "converted into sheep walks".

established Some removals for sheep were tied directly to emigration. In 1826 Maclean of Coll paid for 300 of the 350 people of Rum to go to Cape Breton and let the island to a single sheep farmer, who paid nearly three times the rent of the evicted tenants. In 1838 the Lewis chamberlain Thomas Knox admitted that 70 emigrants whose fares the proprietor had paid "did not wish to go, but farms were cleared to make sheep walks". Sheep displaced people in the south too: Harper notes that in the Southern Uplands commercial sheep farming had since the eighteenth century reduced arable land and displaced people "in a manner reminiscent of the Highlands", and that James Hogg, the Ettrick Shepherd, lamented the emigration of "brave and intelligent Borderers".

shared Harper qualifies a simple link between sheep and exile. She argues that most eighteenth-century Highland emigrants were middle-ranking tenants who paid their own way, often against their landlords' wishes, and that rising rents and the break-up of townships mattered as much as sheep. After 1815, when kelp, cattle and distilling collapsed, sheep farming was "the only sector of the economy that was still buoyant", and landlords gave it more land as they turned to promoting emigration. Historians who stress coercion, such as Eric Richards and James Hunter, agree on the economics but give more weight to eviction.

Saving the Shetland sheep, spreading the Cheviot

In 1790 Sir John Sinclair and the agricultural writer James Anderson persuaded the Highland Society to rescue the Shetland sheep, whose fine wool they believed was the last remnant of Britain's medieval fine-wool breeds. A small flock of four rams and six ewes was shipped to Leith and kept on the island of Inchcolm in the Firth of Forth. Sinclair then founded the British Wool Society (1791–94), which within a year held some 800 sheep, many of them Merino crosses, and sent more than 550 to proprietors across Scotland.

The same campaign helped spread the Cheviot. After the Wool Society's surveyor Richard Ker recommended the Border breed in 1791, Sinclair shipped fifty rams and a hundred ewes 350 miles to Caithness in 1792 and divided them among forty to fifty farmers. Fredrik Albritton Jonsson notes that the sheep frontier crossed the Great Glen only after 1792. In December 1812, as the Sutherland clearances entered their most notorious phase, Sinclair boasted that he had been instrumental in spreading the Cheviot across the northern Highlands. He never seems to have doubted that sheep and Gaels were compatible.

Before the Cheviot: mouflon, Soay, Boreray and North Ronaldsay

established An imported animal. The Handbook of British Mammals (1991), in its account of feral sheep by D. J. Bullock, records that no wild sheep have lived in Britain or Europe since the Ice Age. Domestic sheep descend from the Asiatic mouflon, Ovis orientalis, of south-west and central Asia, and were first domesticated there about 9,000 years ago. The mouflon of Corsica, Sardinia and Cyprus are not truly wild either, but feral relics of early domestic sheep taken to those islands in prehistoric times. The Handbook's history chapter, by D. W. Yalden, says sheep and goats arrived in Britain with Neolithic farmers, about 5,400 radiocarbon years ago.

established The Soay. For centuries the Soay sheep survived only on the island of Soay in the St Kilda group, where the population was put at 150 to 300. It is small, narrow-bodied, long-legged and short-tailed, more like wild sheep than improved breeds: in good condition rams weigh up to about 35 kg and ewes 26 kg. Its coat is mainly wool, coloured from light fawn to blackish with a pale belly and rump, and it casts its fleece in summer. Its bones resemble those of sheep from late Neolithic, Bronze Age and Iron Age sites, though the Handbook notes that an introduction by Vikings or in early Christian times is equally likely. After the St Kildans and their sheep left Hirta in 1930, 107 Soays were moved there in 1932. Between 1952 and 1987 Hirta's flock swung between 610 and 1,783 animals, with periodic die-offs in late winter.

established The Boreray. The Boreray sheep, confined to the island of Boreray, is the breed the St Kildans shepherded, left behind because they could not gather it before the evacuation. The Handbook describes it as a cross between the Blackface, which reached Scotland in the eighteenth century, and the Old Scottish Shortwool, the older native type now represented by Orkney and Shetland sheep. Boreray sheep are small, always horned, and mostly cream to off-white. In 1980 a land count found 699 on the island, about 12 per hectare, a very high density probably sustained by pasture fertilised by seabird droppings.

established Seaweed eaters. The Handbook's habitats chapter, by G. B. Corbet, notes that the sheep of North Ronaldsay in Orkney, a local breed, regularly feed on seaweed.

established A living link. Both St Kilda breeds were classed as rare breeds by the Rare Breeds Survival Trust in 1991, and managed with minimal interference. The Handbook regards the Soay as "an important link" with the sheep first brought to Britain in prehistoric times. It also notes that the name "St Kilda" was once given to the four-horned breed now called the Hebridean. These hardy island sheep are survivors of the older world of Scottish sheep that existed before the Blackface and the Cheviot arrived.

• In 1790 a flock of four Shetland rams and six ewes, thought to be among the last of an ancient fine-wool breed, was kept for safekeeping on the island of Inchcolm in the Firth of Forth (Jonsson, 2013).
• Scotland's Soay sheep, from St Kilda, are more like wild sheep than any improved breed, and cast their fleece every summer.
• The Boreray sheep is the St Kildans' own breed, left behind on Boreray at the 1930 evacuation.
• North Ronaldsay sheep in Orkney regularly eat seaweed.
• In 1775 Andrew Wight predicted that Highland landowners who switched to sheep would soon go back to black cattle.
• The Cheviot sheep breed, central to the Highland sheep farming expansion, is directly associated in historical memory with the Clearances precisely because its introduction so often coincided with the eviction of tenant communities from the same land.
• Some of the most notorious and extensively documented clearance activity occurred on the Sutherland estates, where entire glens were cleared of their populations to make way for large-scale sheep farming.
• Displaced Highland communities were frequently relocated to marginal coastal crofting townships, land poorly suited to supporting the population moved there, compounding the hardship caused by the clearances themselves.
• The Highland Potato Famine of the 1840s struck remaining Highland tenant communities particularly hard, worsening conditions already strained by ongoing clearance activity and accelerating emigration.
• Significant Highland emigration driven partly by the Clearances helped shape Scottish diaspora communities in parts of Canada, the United States, and Australia, with lasting cultural memory of the displacement in those communities.
• In some areas, sheep farming was itself later superseded by deer estates for sporting use, as landowners again recalculated which use of the land offered the best commercial return.
• The wool produced by Highland sheep farming fed into Scotland's wider textile economy, including the Scottish Borders' woollen and tweed manufacturing industry, though that industry developed its own distinct industrial history.
• The claim that the Clearances were an economically necessary modernisation, sometimes advanced in landowner-sympathetic historical accounts, is strongly disputed by the weight of social historians and by Highland oral history and testimony.

• The Oxford Handbook spells the sheep farmer's estate "Corychvilly"; the usual spelling is Corychoillie (Cameron of Corychoillie, a Lochaber drover and sheep farmer). This card uses the usual form.

• Do not present sheep farming's role in the Clearances as a minor or incidental factor; it is documented as the primary economic driver of the evictions across most of the Highlands.

• Do not present the landowner-sympathetic "necessary modernisation" framing of the Clearances as a settled, balanced historical consensus; it is a disputed minority position weighed against the great majority of social-historical scholarship and Highland community testimony.

• Do not conflate Highland sheep farming's wool output with the Scottish Borders woollen/tweed manufacturing industry; these are related but historically and industrially distinct topics, with the Borders industry covered in its own dedicated article.

• Do not call Soay or Boreray sheep wild sheep; they are feral domestic sheep, and Britain has had no wild sheep since the Ice Age.

• Do not state as fact that Soay sheep reached St Kilda in the Neolithic; their bones resemble prehistoric sheep, but a later Viking or early Christian introduction is equally possible.

• Do not state precise eviction or emigration numbers as fixed, universally agreed figures; historical estimates vary by estate, period, and source, and should be presented with appropriate qualification.
