This study discusses demographic, political and intellectual transformations among religious Jews in the last few decades with the aim of predicting the future impact of these developments, particularly the effect that this has had on their presence in Israeli politics and public sphere. It analyses the sources of their power, or more precisely, how their influence on the Israeli public sphere has increased. It traces a number of these sources despite differences in their importance and how fixed or intersecting they are: the demographic source, since the number of religious people in Israel is increasing because of natural population growth; the ideological source produced by the political and historical context. It approaches their rising influence on three levels: political, military and public sphere.
