Hundreds of far-right activists marched through Paris on May 6. The march was in memory of Sébastian Deyz, a young man who died in 1994.

"Europe, youth, revolution" came out of the procession. The slogan was imported from Italy in the 1960s by a group that had a lot of tenderness for Hitler, says Nicolas Lebourg, a specialist on the far right in France. "The GUD is their legend, it is something that is unifying, under the flag with Celtic cross," he says.
