This study aims to understand the cultural exchanges and borrowings that occur between violent regionalisms in Europe. Based on a comparative analysis of the figurative traces produced by Basque, Corsican and Northern Irish nationalist movements, this article examines the transnationalization of the representation of violence. Whether it is through the vehicles of symbolism, the symbols themselves or the use of a specific rhetoric, the constellation of common images and iconographic practices serve to reinforce the message and the legitimacy of the group. That being said, the transnational nature of the “culture” of violence, should not hide the peculiarities of each of the nationalist factions, including repertoires of collective action that remain relatively different such as the use of assassination, explosives, as well as whether the violence is directed internally or externally.
