Contrary to received wisdom, the British are not an insular people in the conventional sense - far from it. For most of their early modern and modern history, they have had more contact with more parts of the world than almost any other nation - it is just that this contact has regularly taken the form of aggressive military and commercial enterprise.

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.

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.

A British imperium enabled Scots to feel themselves peers of the Ebglish in a way still denied them in an island kingdom. The language bears that out very clearly. The English and the foreign are still all too inclined to refer to the island of Great Britain as 'England'. But at no time have they ever customarily referred to an English empire.

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.

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.

Most Britons still lived and died without encountering anyone whose skin colour was different from their own. Slaves, in short, did not threaten, at least as far as the British at home were concerned. Bestowing freedom upon them seemed therefore purely an act of humanity and will, an achievement that would be to Great Britain's economic detriment, perhaps, but would have few other domestic consequences.
