Political sociology continues to have a significant place in the study of the relationship between society and politics. The unprecedented US election of 2000 provided many examples of what Braungart suggested in the first of this series in political sociology; that political occurrences are born out of social dynamics. The frameworks political sociologists use to understand, describe, and predict different forms of political participation are shared in this collection of diverse works dedicated to assessing current research and future directions in political participation. Participation in social and political movements now constitutes a significant body of work in political sociology. This volume presents varieties of theoretical frameworks designed to explain political movements. These works also suggest that research in this field is ripe for continued elaboration and testing. The electoral politics of society, whether unusual as presented in our symposium of the 2000 US election or more routine, can be understood in terms of models of political participation that build on the works of political sociologists since the 1970s. In compiling this volume we find the study of political participation to be alive and well, providing fruitful arguments and ideas for research in the next 100 years.
