Due to its artificial and unnatural structure, Israeli society has since the beginning of its establishment, been a context for the emergence of different kinds of cleavages and tensions. This state of affairs has endangered the political stability of the Israeli regime. The present research is trying to answer this question: what is the effect of religious-secular cleavages in Israel on the future of the political stability of the regime? The article hypothesizes that the religious-secular cleavage is one of the most important social cleavages in Israel and its expansion can be considered as a serious threat to the political stability of the regime. The present research indicates that there are three kinds of cleavages in Israel which constitute the most important social cleavages in society: the Arab-Jewish cleavage; the Ashkenazi-Sephardim cleavage; and the religious-secular cleavage. Although all these three cleavages affect Israel’s political stability, we concentrate on the cleavage that exist between religious and secular forces in society as one of the most serious social cleavages in Israel. It undermines Israel's political stability in at least two ways: the cleavage undermines Israel's political legitimacy; and its shift from the social arena into the political arena transforms it into a political cleavage.
