The main character is Adelchi, a Longobard prince torn by the inner conflict between his father Desiderio's will and his own desire for peace. Adelchi is the son of the last Lombard King, Desiderius. The action takes place between 772 and 774, the latter being the year in which Charlemagne, also a protagonist in the tragedy, brought about the end of the Lombard Kingdom
