This article examines three models—moral economy, rational choice, and class structure—that have been applied to rebellions and revolutionary movements in Southeast Asia. All three are found lacking in various ways and unable to provide convincing explanations for the growth and continuing strength of the contemporary revolutionary movement in the Philippines. The Aquino government is challenged by a movement that has a mass base of roughly ten million and fields a fighting force of twenty thousand to twenty-five thousand men and women. It is active in virtually every province and city of the nation. Based on the present case study, suggestions are made both for ways in which the insights of extant theories can be synthesized and ways in which these theories must be revised if they are to be made more generally applicable to today's revolutions.
