Giuseppe Verdi's opera I Lombardi alla prima crociata receives its first performance in Milan, Italy.

I Lombardi alla Prima Crociata (The Lombards on the First Crusade) is an operatic dramma lirico in four acts by Giuseppe Verdi to an Italian libretto by Temistocle Solera, based on an epic poem by Tommaso Grossi, which was "very much a child of its age; a grand historical novel with a patriotic slant". Its first performance was given at the Teatro alla Scala in Milan on 11 February 1843. Verdi dedicated the score to Maria Luigia, the Habsburg Duchess of Parma, who died a few weeks after the premiere. In 1847, the opera was significantly revised to become Verdi's first grand opera for performances in France at the Salle Le Peletier of the Paris Opera under the title of Jrusalem.

Giuseppe Fortunino Francesco Verdi (Italian: [dʒuˈzɛppe ˈverdi]; 9 or 10 October 1813 – 27 January 1901) was an Italian composer best known for his operas. He was born near Busseto to a provincial family of moderate means, receiving a musical education with the help of a local patron. Verdi came to dominate the Italian opera scene after the era of Gioachino Rossini, Gaetano Donizetti, and Vincenzo Bellini, whose works significantly influenced him.

In his early operas, Verdi demonstrated a sympathy with the Risorgimento movement which sought the unification of Italy. He also participated briefly as an elected politician. The chorus "Va, pensiero" from his early opera Nabucco (1842), and similar choruses in later operas, were much in the spirit of the unification movement, and the composer himself became esteemed as a representative of these ideals. An intensely private person, Verdi did not seek to ingratiate himself with popular movements. As he became professionally successful he was able to reduce his operatic workload and sought to establish himself as a landowner in his native region. He surprised the musical world by returning, after his success with the opera Aida (1871), with three late masterpieces: his Requiem (1874), and the operas Otello (1887) and Falstaff (1893).

His operas remain extremely popular, especially the three peaks of his 'middle period': Rigoletto, Il trovatore and La traviata. The bicentenary of his birth in 2013 was widely celebrated in broadcasts and performances.
