A fundamental condition for the evolvement of any society is the development of social identity, which confers a sense of belonging and identification. The meaning of social identity is influenced by the ethos that members of a society share. The ethos consists of shared, central societal beliefs that give the society a dominant orientation and characterize it. The societal beliefs that underlie the ethos can change as a result of new, prolonged experiences of the society. Israeli society presents an example of such a process.

During the years of intractable conflict, Israeli society developed societal beliefs of a conflictive ethos that were conducive to successful coping with the conflictive situation. The ethos included beliefs about the justness of the Jews' goals, about security, and about delegitimising the Arabs, together with motifs of positive self-image, patriotism, unity, and peace. These beliefs characterised Israeli Jewish society and contributed meaning to the Israeli social identity. As the peace process developed, the societal beliefs of the conflictive ethos began to change, at least among part of the society members. But as the violent conflict re-erupted in fall 2000, the ethos of conflict is strengthening its standing in the society. The present paper describes the changes in the conflictive ethos with regard to each of the societal beliefs and discusses the implications of these changes for the meaning of the Israeli Jewish identity. Finally, general conclusions regarding the presented conception of social identity are outlined.
