<p>This book arises out of a specially commissioned issue of West European Politics marking the journal's 30th anniversary. It examines the profound changes in the European political landscape over the last three decades, including the fall of Communism; progressive European integration; territorial restructuring; public sector reforms at European, national, regional and local levels; changes in democratic participation, protest, elections, political communication, political parties and party competition; and challenges to the welfare state. The book also discusses how political science has responded to these changes in terms of its substantive focus, concepts, methods and theories. Many of the 17 contributions included identify important challenges for the future, including those stemming from EU integration, the reduced electoral accountability of politicians, the problematic legitimation of party government and the sharpening of the edges of the state. Contributors include K. A. Anderson, F. C. Castles, C. Crouch, M. Egeberg. M. Ferrera, H. Goetz, L. Hooghe, E. M. Immergut, R. F. Inglehart, M. Keating, H.-D. Klingemann H. Kriesi, M. Lodge, J. Lovenduski, P. Mair, G. Marks, Y. Mény, L. Morlino, H. Obinger, V. A. Schmidt, P. C. Schmitter, and G.
