This article examines the Portuguese maritime epic through the discourses of gatekeepers, particularly members of the Portuguese parliament. The study positions the maritime epic as a crucial element of Portuguese identity and self-esteem, central to an ongoing culture war over the past and the contestation of official narratives. The analysis reveals that, while the maritime epic serves as a ‘lieu de mémoire’ for collective memory, it is increasingly contested by decolonial movements and actors. The findings indicate (i) a left–right polarisation and (ii) a more nuanced, depolarised stance among mainstream political actors, characterised by two distinct approaches: a voluntarist perspective, advocating for revising the narrative, and an antivoluntarist stance, expressing caution regarding the terms of the debate.
