Jacobitism involved much more than a debate about the merits of a particular dynasty. Men and women were well aware that its success was almost certain to involved them in civil war. And the more politically educated knew that the Stuart Pretender was a pawn in a worldwide struggle for commercial and imperial primacy between Britain and France.

The pre-war empire had been sufficiently informal and sufficiently cheap for Parliament to claim authority over it without having to concern itself too much about what this authority entailed. The post-war empire necessitated a much greater investment in administrative machinery and military force. This build-up of control had to be paid for, either by British taxpayers or by their colonists.

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.

In the last quarter of the 20th century, Britons have been understandably obsessed with the problem of having too little power in the world. In the third quarter of the 18th century, by contrast, their forebears were perplexed by the problem of having acquired too much power too quickly over too many people.

An unprecedented number of uniformed males, marching, parading and engaging in mock battles in every region of Great Britain brought a pleasant frisson of excitement into many normally quiet and deeply repetitive female lives.
