The sixth volume in Greenwood’s ongoing series, this book is the first of three volumes to cover the 20th century and the last stages of decolonisation of the British Empire. It is concerned with the original five Dominions, the apparently inappropriate association of the Irish Free State with those Dominions, and the similarly anomalous status of India, the first non-European dependency and the first republic to secure full membership in the Commonwealth and to make it a multiracial association. The book documents the evolution of, changes in, and rise and fall of that Commonwealth association; the shifts in the balance of powers within the Canadian and Australian federations; the fulfilment of union in South Africa and Ireland; the coherence emerging in New Zealand; the bankruptcy in Newfoundland; and the separation of India and Pakistan. Two forthcoming volumes will deal with the colonies, protectorates and mandates in the 20th century.
