The Political Mistress: Intimacy, Emotion, and Parliamentary Politics in the Late 18th Century

Between c.1796 and 1809, Lady Harriet Ponsonby, Countess Bessborough and Lord Granville Leveson Gower were embroiled in a passionate affair. Their liaison created tensions in aristocratic society because they belonged to rival political parties, the Whigs and the Tories respectively. In the early years of their relationship, Leveson Gower was emerging on the political scene, while the countess was already well-versed in the complexities of party politics. Leveson Gower thus solicited her advice and support and Bessborough duly shared her knowledge and insight into the political world, which created an unusual dynamic that scholars have yet to explore. This article examines several letters that Bessborough wrote to Leveson Gower to analyse how she supported her lover's fledgling parliamentary career and how she navigated their political differences. I argue that Bessborough adapted a rhetoric of affection, deference, duty, and loyalty, that was typically used by aristocratic wives, to justify her interest in her lover's career and her passion for parliamentary politics. This article contributes to scholarship that explores aristocratic women's political participation by examining the strategies a political mistress could employ to exert influence over men. It also illustrates the value of using methodologies from the history of emotions to investigate the drives and passions that shaped interactions in the late 18th-century political sphere.
