This study examines how the British Empire of the 18th century contained revolution by integrating opposition agents as new spaces of power opened up. Monika Barget convincingly argues that this process of constitutionalisation meant that groups from the aristocracy to religious communities, from the army to the people at large, were brought into the system in a way that balanced the obvious, serious challenges that the Glorious Revolution, the Jacobite Rebellion, the American Revolution, and Jacobin threats of the late-18th century posed to the Empire. Barget highlights the lasting political and legal repercussions of this process. The structure of the chapters, each focussing on specific agents and conflict media, also links the history of political agency and political institutions with an expanding European and even trans-continental media market.
