In virtually every Continental state at this time, aristocracies had to live with the risk that their property might be pillaged or confiscated. Only in Great Britain did it prove possible to float the idea that aristocratic property was in some magical and strictly intangible way the people's property also. The fact that hundreds of thousands of men and women today are willing to accept that privately owned country houses and their contents are part of Britain's national heritage is one more proof of how successfully the British elite reconstructed its cultural image in an age of revolution.

Loyal and substansial Catholic service on the battlefield undermined one of the most longstanding objections to emancipation: namely, that since Catholics owed religious allegiance to a foreign authority in the person of the Pope, their political and patriotic allegiance must necessarily be suspect.

In the wars against Revolutionary and Napoleonic France, as in so many later conflicts, British women seem to have been no more markedly pacifist than men. Instead, and exactly like so many of their male countrymen, some women found ways of combining support for the national interest with a measure of self-promotion. By assisting the war effort, women demonstrated that their concerns were by no means confined to the domestic sphere. Under cover of a patriotism that was often genuine and profound, they carved out for themselves a real if precarious place in the public sphere.

These developments - a massive transfer of land by way of inheritance and purchase, an unprecedented rise in the profitability of land and increasing intermarriage between Celtic and English dynasties - helped to consolidate a new unitary ruling class in place of the more separate and specific landed establishments that had characterised England, Scotland, Wales and Ireland in the Tudor and Stuart eras.

A fundamental reason why Britain was not torn apart by civil war after 1688 was that its inhabitants' aggression was channelled so regularly and so remorsely into war and imperial expansion abroad.

Virtually every war fought since the Act of Union had gone badly at some stage, but before 1783 none had ended in defeat. Nor would any major war in which Britain was involved after this date end in defeat. Those who are curious about this country's peculiar social and political stability probably need look no further than this for essential cause.

Can it be entirely accidental that the most famous fictional spy of them all, James Bond, Number 007, deadly marksman, intriguer, the ultimate man behind the curtain, sexual athlete and ruthless patriot, is also a Scot, as was the author, whose wish-fulfilment he was?
