This collection brings together leading political scientists in order to address the challenges faced by democracy in the 21st century. The contributors tackle the changing nature of democratic ideas, in particular equality in society and the satisfaction of citizens. They examine changing patterns of political involvement, from voting to new forms of participation and protest using the Internet and new technologies. Finally, they look at the challenge to democracy posed by the changing nature of state institutions: party systems, bureaucracy and e-government, regulation and the processes of institutional development.
