This "Reign of Terror" (La Terreur) is becoming highly controversial amongst academic historians. Don't believe everything on wikipedia, even if it fits your views.
I'm not saying that Furret is a bad historian: he is the reason why we can be closer to the truth, now. By disproving some of the marxist interpretation claims and advancing his own interpretation, he allowed younger historian to do the same to his own, finding proofs through legislative archives that some "French revolution facts" were not really facts, and especially, the legend about the assembly: "La Terreur est a l'ordre du jour".
French textbook still have not been updated, and neither was wikipedia :/
