The pamphlet debate concerning the perceived effects of parliamentary enclosure on property and population in eighteenth-century Britain has been largely neglected by intellectual historians. One consequence of this debate was to undermine the credibility of the classical republican economic vision of agrarian simplicity, due to its proponents' failure to come to terms with the enormous disjunction between ancient and modern economies. Although the enclosure of agricultural land had provoked hostility since at least the fifteenth century, after 1700 its opponents developed new arguments to take account of the legislature's increasingly prominent role in facilitating the process. In doing so, anti-enclosure writers drew on classical republican ideas, arguing that enclosure was contrary to the public interest because it eroded the independence of the yeomanry, valorized by numerous republican authorities as integral to the country's military strength. In their criticisms of modern policy, these writers praised the agrarian laws of the Roman republic, as well as the Tudor tillage acts. The agricultural ‘improvers’, on the other hand, denied the validity of these precedents on the grounds that the historical contingencies which had produced the Roman agrarian laws, or the Tudor tillage acts, were of limited relevance in a society based on the interdependence of agriculture, manufactures, and commerce.
