In a study examining the history of Euroscepticism since 1945, this book argues that opposition to Europe has been shaped decisively by the opportunities available to sceptics to oppose government policy and the arena in which European policies have been made. The book argues that opponents to European integration have evolved from a group of anti-Europeans, into anti-marketeers and finally into a mainstream group of Eurosceptics committed to opposing political, economic and monetary union agendas. Anthony Forster argues that Euroscepticism, in addition to being a political stance, displays the seeds of becoming a new faith. Through a detailed analysis of British post-war politics he shows the development of a core set of beliefs, a history of persecution, displays of moral rectitude in opposing Europe and the power of scepticism to change existing beliefs. This challenging new history of Euroscepticism should be a valuable resource for undergraduate students of politics and European studies.
