Attila is an opera in a prologue and three acts by Giuseppe Verdi to an Italian libretto by Temistocle Solera, based on the play Attila, König der Hunnen ("Attila, King of the Huns") by Zacharias Werner. Initially, Verdi had enlisted Francesco Maria Piave to prepare the libretto, after Verdi's own scenario. After finding Piave's work unsatisfactory, Verdi then turned to Solera, but finally returned to Piave for Act III. The opera received its first performance at the Teatro La Fenice, Venice, on March 17, 1846.
