We defy the most learned chronologist, the most intelligent annalist, the most industrious antiquary, and the most diligent inquirer into the facts and records of past times, to produce from history, ancient or modern, any parallel for such situations. In truth, no such nation as the United States, all circumstances considered, has ever been discovered in the political hemisphere.1 So the Anti-Jacobin Review summed up the enigma that the American republic continued to constitute for conservative observers in Britain in the early decades of its existence. In this particular instance, months before the outbreak of the Anglo-American War of 1812, the writer was both confounded and outraged that 'a nation, insignificant in the scale of power, in the infancy almost of civilization, and with a circumscribed revenue, arising from sources over which she had not absolute controul' should be 'publicly discussing, in her legislative bodies, not only the propriety and necessity of war with a friendly state, but the means of carrying it on, and the objects to which it should be directed!' 2 How to square the circle of presumed American incompetence with a rising anxiety regarding its potential was an unspoken (and perhaps unrecognised dilemma) for British conservative commentators during these decades.Conservative writers articulated a largely hostile attitude towards the United States of America between 1792 and 1820. They admitted that there were some reasons to admire the achievements of the new republic; and apprehension, which was also expressed, implies some form of respect.It proved to be much too soon yet, however, for writers at this end of the British political spectrum to admit the reality of the establishment of a successful federal republic in place of their thirteen colonies, to 'embrace closure', and to accept that they had departed from the British empire without disintegrating into inter-state conflict, political collapse, economic ruin and loss of all international stature. They had been convinced that an American republic was not viable, 2 and they had fully expected the attempt to result in disaster. Their response to its realization and flourishing was a mixture of resentment, contempt and fear. Moreover, their stance on British political issues which emerged during these decades -parliamentary reform, defence of the British empire, and the question of free trade -also determined that their attitude towards America was unlikely to be appreciative. Indeed, for much of the time they were really discussing British politics through the prism of America. The American constitution, American party politics, American grievances concerning the British navigation laws, Canada, emigration to North America, and the Anglo-American relationship were all deeply interesting matters in themselves. But they also allowed conservative writers to expound scorn for representational politics involving a wide franchise and weak central government; suspicion of reformers; support for protectionist commercial policy, imperialism,...
