Sora was declared a royal city by the king of Naples, Charles I Anjou in the 14th century; in the following centuries its lords were the Tomaselli, Cantelmi, Della Rovere and Boncompagni families. In 1798 Sora was a center of resistance against the French, under the leadership of brigands as Gaetano Mammone and Michele Pezza, called "Fra’ Diavolo".
The town was greatly damaged by the 1915 earthquake. Sora was also the birthplace or film director Vittorio De Sica (Sora 7th July 1901- Neuilly France 1974).
