Abstract
This article provides a comparative case study of the development of identity distinctions between two peace movement organizations during the Persian Gulf crisis . Distinctions between these two SMOs' identities are traced through their collective action frames and through self evaluative framing . It is found that the identities are related to the SMOs' organizational structures , their career stages , and their desired positions in relation to the ''mainstream'' and past movement identities . Implications for effectiveness of such identity making is considered .
