Aimée Dion is a doctoral student in History at Laval University (Quebec City, Canada). Through the use of comparative history, her thesis project focuses on the political use of images and on the construction of war cultures. She is primarily interested in the visual representations of the First World War in Ireland and Quebec between 1914 and 1918. Her research focuses on the representation of nationalism and on the construction of collective identity and political culture through posters. By studying war posters and cultural posters, she examines the mobilizing force of images. Her master’s thesis explains the impact of World War I on the parallel nationalist trajectories of Ireland and Quebec, the global conflict acting as a catalyst to their diverging nationalist paths.
