Conspiracy theories in France

Rennes-le-Château (; ) is a commune approximately 5 km (3 miles) south of Couiza, in the Aude department in the Occitanie region in Southern France.

The Great Replacement, also known as replacement theory or great replacement theory, is a debunked white nationalist far-right conspiracy theory coined by French author Renaud Camus. Camus's theory states that, with the complicity or cooperation of "replacist" elites, the ethnic French and white European populations are deliberately being replaced by non-white peoples—especially from Muslim-majority countries—through mass migration, demographic growth and a drop in the birth rate of white Europeans. Since then, similar claims have been advanced in other national contexts, notably in the United States. A consensus of academic scholars have dismissed these claims of a conspiracy of "replacist" elites as rooted in a misunderstanding of demographic statistics and premised upon an unscientific, racist worldview.
