Britannia's Zealots, Volume I opens the first longitudinal study to examine the Conservative Right from the late-19th century to the present day. British Conservatism has always contained a significant section fundamentally opposed to progressive reform. A permanent minority in Parliament, dissident right-wing Conservatives nevertheless had allies in the press and sympathy among grassroots party members enabling them to create crises in the media and at party meetings.

N.C. Fleming charts the evolution of reactionary politics from its preoccupation with the Protestant constitution to its fixation with the prestige and strength of Britain’s global empire. He examines the overlooked ways in which Conservative Right parliamentarians shaped their party’s policies and propaganda, in and out of office, and their relationships with the press and ordinary activists. He seeks to demonstrate that this influence could be circumscribing, and on occasion highly disruptive, with consequences which remain relevant for today's Conservative party. Britannia’s Zealots, Volume I will be of great interest to academics and students of British history, right-wing politics, imperialism, and 20th-century history.
