It uses the largely unused archive of the House of Lords, which survived the parliamentary fire in 1834, to provide systematic evidence of public subscription to petitions produced in response to legislation. A total of 330 “large responsive petitions,” signed by fifty-six thousand people, were presented to the Lords between 1688 and 1720. This enabled a wide range of social and geographical groups to lobby Parliament. Parliamentarians actively sought to direct the public into voicing opinion through petitioning on matters of policy. The intervention of the language of “interest” from the mid-seventeenth century helped to legitimize and control public involvement in politics in the eyes of elites, and offered an alternative to political mobilization based on party allegiances and conceptions of society organized by ranks or sorts. The participation of the public through a regulated process of petitioning ensured that the whig oligarchy was porous and open to negotiation, despite the passage of the Septennial Act and declining party and electoral strife after 1716.</jats:p>
