There is a very (very) long history of terrorist attacks in France from a wide variety of groups. https://fr.wikipedia.org/wiki/Terrorisme_en_France https://fr.wikipedia.org/wiki/Terrorisme_en_France (link to the French one, the English version is shorter) Only looking at post-WWII, you have far-right groups, far-left groups, Corsican regionalists, Basque regionalists, various independentists (Breton, New Caledony, Caribbean, etc.), extension of the Algerian civil war of the 90s, etc. Those account for hundreds of attacks, with a various amount of deads. Only recently have Islamist attacks begun. The most lethal single attack until today in France was in fact from a far-right group in the 60s.
