Continuity and Change in Philippine Politics

First Published in 1992. This book examines the elements of continuity and change in Philip pine politics and government over the last quarter century. The period covered, from the early 1960s through 1988, encompasses three distinct phases: the decline of traditional elite democracy, the imposition of martial law and constitutional authoritarianism under Ferdinand Marcos, and, most recently, the restoration of democracy under Corazon Aquino.
