John T. Sidel, London School of Economics and Political Science. This lecture shows how Communism and Islam played a crucial, constitutive role in the making of the Indonesian “Revolusi,” suggesting the essentially cosmopolitan nature of its origins and its emancipatory energies. John T.

This talk covers a set of chapters in a book he is completing, titled Republicanism, Communism, Islam: Cosmopolitan Origins of Revolution in Southeast Asia, which he hopes to complete this year.
