Stability and changeability of identities, especially in the context of their disappearance and revival, is one of the leitmotifs of the current publication, which is a fruit of a collective effort of scholars who represent diverse areas of the humanities and varied approaches to the issue of identity in the lands occupied by the Persian-language civilization. Treating the issue of identity in an interdisciplinary manner made it possible to present it from a variety of standpoints, consequently yielding a complex picture of the matter. Moreover, as it often happens when an interest in a certain research problem is shared by many specialists, new perspectives were discovered. The effect of synergy that emerged during the preparation of this publication undoubtedly adds to its quality. In addition, whereas sociologists and psychologists have long conducted research on identity or identities, an approach to the subject made from the point of view of Oriental Studies is to some extent an innovation and constitutes an interesting challenge.
