This thesis is based on a long-term field research in the Prague Jewish community in which I am trying to express the Jewish identity of young Czech Jews. The aim is to characterize the formation and construction of Jewish identities, their coexistence with other types of social identities and the role of material elements in this process. The formation has a processional nature and there are continual transformations and negotiations of concrete forms of Jewish identities over time. These identities are publicly manifested through various material elements and by this manifestation those identities are also strengthened. I also examine the impact of physical structures and other objects on the Jewish community, how they strengthen its cohesion and on the role that they play in materializing and bringing the collective memories into the present. I simultaneously work with the concept of materiality in the context of the Moishe House Prague project. I examine the position of techno-social tools and the power of leadership. This thesis is based on several theoretical perspectives that I connect and combine in order for me to explore social reality and Jewishness in their entirety.
