‘The next necessary thing’, wrote Clifford Geertz in The Anthropologist as Author, ‘is to enlarge the possibility of intelligible discourse between people quite different from one another in interest, outlook, wealth and power, and yet contained in a world where, tumbled as they are into endless connection, it is increasingly difficult to get out of each other’s way.’ New nationalisms are part of that connection, and part of the resultant structures of evasion, or ‘identity’. Mongrels need new rules. And all nations are becoming mongrels, hybrids or foundlings, in the circumstances of globalization.

This is the overall impression left by Michael Fry’s definitive new book, The Union: England, Scotland and the Treaty of 1707—both a careful history of the Treaty of Union, detailing in particular the years from 1698, and a polemical argument for its repeal, and for the resumption of Scottish independence. Note, ‘resumption’ rather than ‘claiming’. Its appearance could hardly be more timely. May 1st, 2007 will mark the 300th anniversary of the ‘United Kingdom of England, Wales, Scotland and Ireland’. This elderly piece of multiculturalism has endured alternative titles, ‘Britain’ and ‘Great Britain’ for example, all intended to make it sound more united than it ever was. People appear to be getting used to the idea of Iraq disappearing, divided between Kurdistan and one or more Muslim-Arab states. But an analogous fate may overtake Britain’s faltering Union, if Scotland, Wales and Northern Ireland opt for new directions at the May 2007 elections to their ‘devolved’ assemblies. In that case a new acronym may soon come into play, the ‘ruk’ (‘Rest of the uk’). This would be mainly England of course, though now with the curious sense of ‘Little England’ plus London—a cosmopolis with nothing little about it, outside of Westminster and Buckingham Palace.

About twenty years ago Eric Hobsbawm, annoyed by my own connections with what then seemed the hopeless cause of Scottish nationalism, reminded me sharply that it was the Scots who really made the British Union in the 18th and 19th centuries. He was implying that to withdraw from the uk would be a retrograde move, and that to try and reform it made more sense. Whatever is now thought of that political recipe, Hobsbawm’s historical judgement was surely right. Though the British Kingdom unites a surprising number of countries and cultures, ranging from Wales to the micro-nations of the Isle of Man and the Channel Islands, its backbone remains the link with Scotland. That rapport, in turn, rests formally upon one thing. This is not an idea, or a sacred code or emblem, or even what sociologists call a ‘habitus’. It is a sheaf of papers.

I recall vividly the first time I set eyes on the Treaty, at a court hearing in the 1980s on Scottish protests over Mrs Thatcher’s Poll Tax. Some Scottish lawyers maintained that a head-count tax might be incompatible with the 1707 Treaty of Union, and hence illegal under Scots Law. The presiding judge testily decided that a copy of the Treaty was required, and dispatched a clerk to make a photocopy from the Signet Library archives. Some hours passed before he returned with a handful of folded sheets—the nearest thing to a written constitution that British statehood has ever attained. A few days later the verdict came. There were no grounds for thinking the Poll Tax incompatible with any clauses of the Treaty, and Scots would have to put up with it. The Treaty hadn’t saved them. The same miserable old sheets would be included, unchanged, in Blair’s 1998 legislation on devolution. So the restored Scottish parliament was to go on being hamstrung by them, exactly like its ancestor of 292 years before.

This and many other absurdities can be made more sense of in the broader perspectives of The Union. Fry’s close scrutiny of the motives for the 1707 Treaty underlines its unique character. It involved neither colonization nor forced assimilation—of the sort displayed earlier in Wales and Ireland—but an international agreement between two frequently battling kingdoms. They had been united under the same monarchy since 1603, but even this had grown precarious. Scottish in origin, the Stuart dynasty constantly threatened an armed come-back after twice being evicted, during the civil wars of mid-century and again in 1688. (The question would not be finally resolved until forty years after the parliamentary Union, at the Battle of Culloden in 1746.) In 1707, Queen Anne’s English parliament was demanding more serious political reform, a single assembly located (naturally) in London and supporting the new Protestant monarchy, forerunner of today’s Windsors. Their hope was for a more united Anglo-Scots ruling class, which would be easily dominated by the English aristocracy. At that time, poor and thinly-populated Scotland represented only a small part of the main island’s population, and even less of its resources.

London’s new urgency was fueled by international problems. An expanding colonial empire could no longer tolerate home-island dissent, least of all from a regime that was showing alarming signs of wanting its own colonies and foreign policy. Scotland had often been allied with France, the dominant great power of the time and England’s chief competitor. The Stuarts were in exile in France, and counting on diplomatic and military support from Louis xiv. At the same time, the condition of the Scottish economy had become pitiable. No-one will ever be sure what percentage of the population starved to death during the terrible 1690s, a period to which Fry pays great and deserved attention. In these circumstances, the Edinburgh political elite sought an over-ambitious remedy: launching a colonial enterprise of its own, by occupying the Isthmus of Darien (today’s Panama).

A joint counter-attack by England and Spain defeated this venture in 1698–99 but, as Fry recounts, simultaneously emphasized the need for London to close the northern ‘back door’. After the assimilation of Wales and Ireland, a different solution had to be found for the Scots. In contemporary terms, ‘security’ called for a political deal, rather than the dangers of occupation and repression. The English knew they could defeat Scotland’s formidable clannic armies. They had done so already in Cromwell’s time, but at huge cost; in today’s world, comparable perhaps to recent assaults on Afghanistan. A much better solution was to buy off the northern aristocracy and warlords (including some compensation for their humiliation over Darien).
