In Renaud Camus on Remigration: The Bourne Speech, Camus argues that mass immigration into Europe is a form of colonization, which he calls "the Great Replacement", and that only remigration, meaning the organized return of immigrants, can preserve European nations and civilization. He criticizes the legal and political systems that protect this demographic shift, calling them part of a broader ideology he terms "Global Replacism", driven by elites, international finance, and ideological conformity. Camus compares the current situation to historical occupations, and calls for a peaceful but determined decolonial resistance, based on civil disobedience and national renewal. He was denied entry to the United Kingdom to deliver this speech at the "Big Remigration Conference" on April 26, 2025, organized by the Homeland Party.
