This work traces the early rise and subsequent decline of politically effective student activism in Malaysia. During the 1970s, the state embarked on a project of “intellectual containment” that both suppressed ongoing mobilization of university students and delegitimized further activism. That project has been notably successful in curbing student protest, erasing a legacy of past engagement, and stemming the production of potentially subversive new ideas. Innovative student proposals for reform that were once sanctioned and even welcomed (within bounds) are now illicit and discouraged, reflecting not only changes in Malaysia’s political regime, but changes in the political culture overall. This incisive study sheds new light on the dynamics of mobilization and on the key role of students and universities in postcolonial political development.
