Book excerpt: Beginning in 2005 as a small electoral reform initiative, the Coalition for Clean and Fair Elections, known as Bersih, became the most prominent social movement in Malaysia. Based on participant observation approach and first-hand interviews with key actors, this book examines how Bersih became a movement that aggregated the collective grievance of Malaysians and brought Malaysian sociopolitical activism to a new level. This book makes a major contribution to the scholarly work on social movement theories in the Southeast Asian context and to the growing literature on social movements and democratization.
