Giuseppe Fortunino Francesco Verdi (9 or 10 October 1813 – 27 January 1901) was an Italian Romantic composer primarily known for his operas. He is considered, with Richard Wagner, the preëminent opera composer of the 19th century. Verdi dominated the Italian opera scene after the eras of Bellini, Donizetti and Rossini. His works are frequently performed in opera houses throughout the world and, transcending the boundaries of the genre, some of his themes have long since taken root in popular culture, examples being "La donna è mobile" from Rigoletto, "Libiamo ne' lieti calici" (The Drinking Song) from La traviata, "Va, pensiero" (The Chorus of the Hebrew Slaves) from Nabucco, the "Coro di zingari" (Anvil Chorus) from Il trovatore and the "Grand March" from Aida. Moved by the death of compatriot Alessandro Manzoni, Verdi wrote Messa da Requiem in 1874 in Manzoni's honour, a work now regarded as a masterpiece of the oratorio tradition and a testimony to his capacity outside the field of opera. Visionary and politically engaged, he remains – alongside Garibaldi and Cavour – an emblematic figure of the reunification process (the Risorgimento) of the Italian Peninsula.
