Wide-ranging, well-informed and measured in its judgements, Willie Thompson's new book provides a first-rate introduction to movements and ideas in the so-called `age of ideologies'---<BR><BR>Kevin Morgan Professor of Governance and Development in the School of Social Sciences, University of Manchester<BR><BR>This is a history of political ideologies during the period famously described by Eric Hobsbawn as "The Age of Extremes'-- from the First World War to the collapse of the Soviet Union.<BR><BR>Ideologies in the Age of Extremes introduces the key ideologies of the age: liberalism, conservatism, communism and fascism. Willie Thompson identifies the political influence of mass movements as a key feature. He uses a powerful approach that considers the different ideologies in relation to each other. This allows him to show that they often emerged from a common root or merged into a common future, stealing each other's clothes and reinventing themselves as the stark opposite of a competing ideology.<BR><BR>This sophisticated yet accessible analysis will be of great interest to students of twentieth-century history and political theory.
