The far right is achieving unprecedented electoral success, even in countries once considered immune such as Spain and Portugal. For decades, the stigma surrounding the long dictatorships of António Salazar and Francisco Franco seemed to inoculate the Iberian Peninsula against far-right mobilisation, yet Chega and VOX have shown that collective memory evolves – and stigma fades. This Element argues that understanding the far right's global rise requires attention to authoritarian nostalgia: a longing for an idealised authoritarian past. When activated by credible political actors with sufficient media visibility, this sentiment can generate support for far-right movements even in societies with a collective memory firmly condemning their authoritarian past. Using original survey data, the Element shows how contemporary far-right forces mobilise the ghosts of authoritarianism to erode democratic norms, revealing the enduring power of collective memory in shaping political behaviour.
