The Prosperous Justice Party (PKS) is the most interesting phenomenon in contemporary Indonesian politics. Not only is it growing rapidly in membership and electoral support, it is also bringing a new and markedly different approach to Islamic politics, one which has no precedent in Indonesian history.
Understanding PKS and analysing its political behaviour presents challenges to scholars and observers. This is partly due to the fact that the party represents a new trend within Indonesian Islam which has few parallels with preceding movements.
