Britain's Declining Empire: The Road to Decolonisation, 1918-1968An authoritative political history of one of the world's most important empires on the road to decolonisation. Ronald Hyam's 2007 book offers a major reassessment of the end of empire which combines a study of British policymaking with case studies on the experience of decolonization across Africa, Asia and the Caribbean. He describes the dysfunctional policies of an imperial system coping with postwar, interwar and wartime crises from 1918 to 1945
