Although social movements and media can destabilize authoritarian governments, not all social protest is effective or culminates in the toppling of dictatorships. Frequently, the military’s response determines the outcome. Terence Lee uses four case studies from Asia to provide insight into the military’s role during the transitional phase of regime change. Lee compares popular uprisings in the Philippines and Indonesia – both of which successfully engaged military support to bring down authoritarian rule – with protest movements in China and Burma which were violently suppressed by military forces. Lee’s theory of “high personalism” and power-sharing among the armed forces leadership provides a framework for understanding the critical transitory phases of democratization.
