This volume provides the first detailed analyses of the ‘Anglosphere’ – a re-imagined transnational community of the English-speaking peoples – which came to international prominence in the wake of Brexit. It brings together leading international experts to examine the Anglosphere’s historical links to the British Empire. It interprets the shifting political and economic fortunes of this contested idea, the locations where it is enacted and how it continues to inform transnational identities and politics across the English-speaking world today. The volume reveals that although the Anglosphere is founded on a common view of the past, its advocates seek a shared future which is never fully attained. The volume examines the claims of its proponents regarding the Anglosphere's continuities and commonalities, and argues that its post-Brexit potential is in fact undermined by very real historical and contemporary differences. Ultimately, the Anglosphere is an unsuitable vehicle for ‘Global Britain’ and for a reordering of the West in international relations. This book will appeal to those interested in the causes and consequences of Brexit, right-wing politics in the UK, the USA, Australia, New Zealand and Canada, and the shifting international relations of the twenty-first century.
