After the fall of the Roman Empire the form of government established by the northern conquerors incapacitated them in a great measure from further conquests, and long maintained each state in its proper boundaries; but when vassalage and the feudal militia were abolished mankind were anew alarmed by the danger of universal monarchy, from the union of so many kingdoms and principalities in the person of the Emperor Charles. But the power of the house of Austria, founded on extensive but divided dominions, and their riches, derived chiefly from mines of gold and silver, were more likely to decay, of themselves, from internal defects, than to overthrow all the bulwarks raised against them. In less than a century the force of that violent and haughty race was shattered, their opulence dissipated, their splendour eclipsed. A new power succeeded, more formidable to the liberties of Europe, possessing all the advantages of the former and labouring under none of its defects, except a share of that spirit of bigotry and persecution with which the house of Austria were so long and still are so much infatuated.

Europe has now, for above a century, remained on the defensive against the greatest force that ever perhaps was formed by the civil or political combination of mankind. And such is the influence of the maxim here treated of, that though that ambitious nation in the five last general wars has been victorious in four,​[23] and unsuccessful only in one,​[24] they have not much enlarged their dominions, nor acquired a total ascendant over Europe. There remains rather room to hope that by maintaining the resistance some time the natural revolutions of human affairs, together with unforeseen events and accidents, may guard us against universal monarchy, and preserve the world from so great an evil.

Hume's Political Discourses — Part 69

In the three last of these general wars Britain has stood foremost in the glorious struggle, and she still maintains her station as guardian of the general liberties of Europe, and patron of mankind. Beside her advantages of riches and situation, her people are animated with such a national spirit, and are so fully sensible of the inestimable blessings of their government, that we may hope their vigour never will languish in so necessary and so just a cause. On the contrary, if we may judge by the past, their passionate ardour seems rather to require some moderation, and they have oftener erred from a laudable excess than from a blameable deficiency.
