This article seeks to reappraise the role of Prince Frederick as a parliamentarian and also to reconsider the size and significance of his association in both Lords and Commons. Previous studies of Prince Frederick and of the so-called Leicester House grouping have tended to emphasize the prince's limitations as a political figure of real weight, to play down the extent of his activities as a parliamentary figure in his own right and have also paid scant attention to the role of the house of lords in Leicester House's schemes. By reconsidering some of the major political dramas of the 1730s and 1740s, this article aims to redress the balance, arguing that Prince Frederick was an active member of the Lords and that his association, though fluid, was more coherent and significant than is usually acknowledged.
