As part of my doctoral research, I investigate the phenomenon of "unhappy death" and necropolitics in contemporary theatre. In particular, I examine various forms of necropolitics through which the Other (marginalized minorities) is transformed into an unhappy object and thus constructed as an atavistic Other. In doing so, the research demonstrates how affective politics and necropolitics are instrumentalized and operate through multiple cultural and aesthetic forms. Through an interferential yet close reading of the selected plays, my study explores on textual (linguistic, semiotic, grammar, architexture) and performative levels (sound, dance, lightning) how meaning, affect, textual materiality, and performance reenact and simultaneously deconstruct necropolitical structures such as victimization, racism, xenophobia, and heteronormativity, through which the Other is constituted as unhappy object. The project combines deconstruction, the concept of the differend, and the deferral of centred meaning with Sara Ahmed's cultural politics of emotion and other affect theories to analyse how the plays deconstruct "unhappy death" and expose these affective ideologies that illegitimately frame the Other as a threat. In this way, the plays enable a form of necroethical witnessing of the anarchives of the unhappy dead, that, grounded in the differend, does not moralize necropolitics but renders its operations perceptible. The dissertation ultimately aims to reveal these mechanisms and to extend existing theories of affect by examining their political dynamics and impact on cultural archives and their purpose in "the noctrunal bodies" of democracy.
