When Constantine announced Christianity as the official religion of the Roman Empire in 14th century, a great deal of attention has been attracted to the relationship between religion and state and much literature has appeared so far. The literature has not much been directly refered to social scientists, being based on a Christian interpretation of religious societies and a Western concept of state. We are not intended to study the origin of state, yet we are aware of the fact that any intensive study of religion and state should be based on methods rooted in different worldviews rather than in religio-cultural traditions . As a result, religion and state are comparatively studied in this article with respect to worldviews such as Buddhism, Hinduism, Christianity, and Islam.
