Macbeth is an opera in four acts by Giuseppe Verdi, with an Italian libretto by Francesco Maria Piave and additions by Andrea Maffei, based on William Shakespeare's play of the same name. Written for the Teatro della Pergola in Florence, it was Verdi's tenth opera and premiered on 14 March 1847. Macbeth was the first Shakespeare play that Verdi adapted for the operatic stage. Almost twenty years later, Macbeth was revised and expanded in a French version and given in Paris on 19 April 1865.
 

The first version of Macbeth was completed during the time which Verdi described as his "galley years," which ranged over a period of 16 years, and one which saw the composer produce 22 operas. By the standards of the subject matter of almost all Italian operas during the first fifty years of the 19th century, Macbeth was highly unusual. The 1847 version was very successful and it was presented widely.

Pleased with his opera and with its reception, Verdi wrote to Antonio Barezzi, his former father-in-law and long-time supporter about two weeks after the premiere:
 

"I have long intended to dedicate an opera to you, who have been father, benefactor, and friend to me. It was a duty I should have fulfilled sooner if imperious circumstances had not prevented me. Now, I send you Macbeth which I prize above all my other operas, and therefore deem worthier to present to you."

The 1865 revision, produced in a French translation and with several additions was first given on 19 April of that year. It was less successful, and the opera largely faded from public view until the mid-20th century revivals.
