This chapter explores what its author sees as three of the most important, and closely related, recent historiographical themes relating to the articulation but also the impact of British political ideas since 1800: political realities, modernity, and moralities. The chapter analyses the close connections and interplay between these three initially seemingly uncomfortable bedfellows, and argues that collectively they have produced a contemporary historiography that, in crossing boundaries in its consideration of cultural, social, and intellectual history; ideas and action; popular and elite attitudes; high ideals; but also sometimes painful realities, is now richer in its understanding of all of these.
