This book chronicles the expansion and creation of new public spheres in and around Parliament in the early Stuart period. It focuses on two closely interconnected narratives: the changing nature of communication and discourse within parliamentary chambers; and the interaction of Parliament with the wider world of political dialogue and the dissemination of information. Concentrating on the rapidly changing practices of Parliament in print culture, rhetorical strategy, and lobbying during the 1620s, the book demonstrates that Parliament not only moved toward the centre stage of politics but also became the centre of the post-Reformation public sphere.
