The current understanding on the roles of socio religious organizations was being challenged and questioned. The seminar discussed the relationship between the state and the roles of these religious organizations during the Reformasi Era. These were among the important issues because transformation of ideas and movements have occurred within Islamic organizations in Indonesia.Since the beginning of the twentieth century, socio-religious organizations have played important roles in Indonesia’s nation building. Muhammadiyah, NU, and Persis are among the organizations which have contributed significantly to the development of Islam in Indonesia. They have been the driving forces for community development such as in education, socio-political, economy, and health.
