Political historians have recognized that politics and high society interacted in eighteenth-century England; and most would also recognize the presence of elite women in the social world of politicians. These assumptions have not, however, been subjected to much scrutiny. This article takes the social aspects of politics seriously and aims to provide an introduction to social politics – the management of people and social situations for political ends – and, specifically, to the involvement of women therein. Politics in eighteenth-century England was not just about parliament and politicians; it also had a social dimension. By expanding our understanding of politics to include social politics, we not only reintegrate women into the political world but we also reveal them to have been legitimate political actors, albeit on a non-parliamentary stage, where they played a vital part in creating and sustaining both a uniquely politicized society and the political elite itself. While specific historical circumstances combined in the eighteenth century to facilitate women's socio-political involvement, social politics is limited neither to women nor to the eighteenth century. It has wider implications for historians of all periods and calls into question the way that we conceptualize politics itself. The relationship between the obstinately nebulous arena of social politics and the traditional arena of high politics is ever-changing, but by trivializing the former we limit our ability to understand the latter.
