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.

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.

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.

At one level Great Britain at the beginning of the 18th century was like the Christian doctrine of the Trinity, both three and one, and altogether something of a mystery.

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.

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.

Ever since the Reformation, the case of legislation confining Catholics had been constructed primarily to protect a nervously Protestant against what was assumed to be a fifth column in its midst... Ministers believedm with some justice, that Catholics retained an attachment to their exiled co-religionists, the princes of the House of Stuart. After the Battle of Culloden had confirmed Jacobitism's insignificance, however, government attitudes towards Catholicism began perceptibly and logically to relax.
