Based on the reading of the book “Notes Toward a Performative Theory of Assembly” by Judith Butler, the notion of assembly is examined as a plural and embodied action of collective bodies in public space, as it may occur in the form of multiple and different types of protests, demonstrations or political movements. It refers to a form of political performativity that takes place in the public sphere every time individuals assemble, signifying and constituting the imaginary of the multitude. The main question of this paper is whether a form of political assertion through the public display of the body, is condemned to reproduce the national imaginary, or whether it can involve those individuals who stand on the boundaries of the recognizable and whom diverse power relations take them away from an embodied way of living. For example, can the produced space of an assembly be considered as that “crack” in the space of appearance, radically questioning and transforming the character of the latter? An attempt is made to examine the notion of precarity as a common element of demonstrations, as well as the notion of multitude as that changing body of singularities which can challenge and resist. Finally, considering security as the new modern governing technique, new potentialities towards the disconnection of everyday life and public space from its mechanisms are being searched for. The goal of this research study is to analyze the spatial and political dimensions of the assembly and to understand its significant impact on the possibility of emerging imaginaries through and beyond dominant narratives.
