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.

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 past, the British had signally failed to build an effective structure of royal authority and administration in their American colonies. As a result, no possibility existed of soothing and winning over influential and talented Americans, in the way that influential and talented Scotsmen were increasingly being won over, by giving them increased access to state employment.

Recognising that an ostentatious cult of heroism and state service served an important propaganda function for the British elite does not mean, of course, that we should dismiss it as artificial or insincere. All aristocracies have a strong military tradition, and for many British patricians the protracted warfare of the period was a godsend. It gave them a job, and, more important, a purpose, an opportunity to carry out what they had been trained to do since childhood: ride horses, fire guns, exercise their undoubted physical courage and tell other people what to do.

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.

Human beings are many-layered creatures, and do not succumb to the hegemony of others as easily as historians and politicians sometimes imply. Those Welsh, Scottish and Anglo-Irish individuals who became part of the British Establishment in this period did not in the main sell out in the sense of becoming Anglicised look-alikes. Instead, they became British in a new and intensely profitable fashion, while remaining in their own minds and behavior Welsh, or Scottish, or Irish aswell.

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.
