L'Action Française is a French political movement founded in the early 20th century, primarily known for its royalist and nationalist ideologies. It emerged in response to the political instability in France and sought to promote traditional values, advocating for the restoration of the French monarchy and a strong national identity. The movement gained significant influence in the 1920s and 1930s, attracting intellectuals and activists. The organization was associated with the publication of a newspaper also called L'Action Française, which played a crucial role in disseminating its ideas. Over time, it became linked with anti-Semitism and far-right politics, leading to its decline after World War II. Despite this, its legacy continues to influence certain segments of French political thought.
