This article is concerned with the European public theatre system’s relationship with migration. Focusing on the Portuguese theatre landscape and especially Lisbon, the essay will map some of the major issues regarding theatre and migration today, identifying both systemic failures and structural and aesthetic shifts in the public theatres’ engagement with migrant communities. Contemporary performative approaches will be surveyed with a special emphasis on initiatives that go against crisis narratives and position migration as a structural component of society rather than a temporary challenge. The article proposes a shift from aesthesized theatre practices towards activist aesthetics, a politically responsive, participatory and durational practice that would not only introduce counter narratives on migration, but it would be instrumental in re-thinking our national cultural, literary and theatrical canons.
