Pope Gregory IX and the interdict lasted until 1257. Only with the surprisingly fast death of Pope Gregory IX in August 1241 did the situation seemed to relax at first. As a sign of good will Frederick II had the legates released in order to make way for the election of a new Pope. The newly elected Pope Innocent IV, however, should prove to be an equally intransigent opponent as his predecessor. In 1244 he took his exile seat in safe Lyon, where this time the convocation of the First Council of Lyons was achieved, which formally deposed the Emperor.
