This chapter builds on the framework and context established in Chapter 1, which in many ways shaped the political experience of Henry St John, 1st Viscount Bolingbroke (1678–1751). It provides a revisionist interpretation by demonstrating that, rather than an anti-party writer, Bolingbroke is best understood as the promoter of a very specific party, a systematic parliamentary opposition in resistance to what he perceived to be a Court Whig faction in power. Drawing on all of Bolingbroke’s well-known works, as well as his lesser-known journalism and unpublished sources, the chapter shows how most of his writings were calculated to legitimise opposition in the shape of a specific kind of political party: the Country party.
