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.

Chilvalry's essential function, Maurice Keen has written, is always to hold up an idealised image of armed conflict in defiance of the harsh realities of actual warfare. By definition, chivalry also reaffirms the paramount importance of custom, hierarchy and inherited rank.

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.

In Great Britain, woman was subordinate and confined. But at least she was also safe.

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?

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.

From the 15th century to 1688, England and Wales, like Scotland, had been peripheral kingdoms in the European power game, more often at war with each other that with Continental powers, and - except under Oliver Cromwell - scarcely very successful on those occasions when they did engage the Dutch, or the French, or the Spanish.
