This is an aid to anyone interested in the history and politics of Britain in the first half of the 20th century. Purpose built for student needs, it is a practical desk-companion for continuous use on a key phase in the history of Britain. It covers only 31 years - but they are years of such unprecedented change that they link two different worlds, from the imperial certainties of the Edwardian Age to the global anxieties fo the Atom Bomb and the Cold War. It includes: a Chronology of the main political events of the period; lists of ministries, office holders and elections; detailed accounts of political parties; notes on legislation and local government; information and statistics on social issues, including population, education, health, gender, sexuality, crime, the news media and religion; information on economic issues, including trade, prices, unemployment, agriculture, industry, finance, the unions and transport; the main developments in foreign and imperial affairs, and accounts of the two world wars and concise biographies of the key figures of the age.
