Year 1813 (MDCCCXIII) was a common year starting on Friday (link will display the full calendar) of the Gregorian calendar and a common year starting on Wednesday of the 12-day slower Julian calendar.

Giuseppe Fortunino Francesco Verdi (Italian pronunciation: [dʒuˈzɛppe ˈverdi]; 10 October 1813 – 27 January 1901) was an Italian Romantic composer, mainly of opera. He was one of the most influential composers of the 19th century. 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 – such as "La donna è mobile" from Rigoletto, "Va, pensiero" (The Chorus of the Hebrew Slaves) from Nabucco, "Libiamo ne' lieti calici" (The Drinking Song) from La traviata and the "Grand March" from Aida.

Verdi’s masterworks dominate the standard opera repertoire a century and a half after their composition.

Verdi was born the son of Carlo Giuseppe Verdi and Luigia Uttini in Le Roncole, a village near Busseto, then in the Département Taro which was a part of the First French Empire after the annexation of the Duchy of Parma and Piacenza. The baptismal register, on 11 October lists him as being "born yesterday", but since days were often considered to begin at sunset, this could have meant either 9 or 10 October. The next day, he was baptized in the Roman Catholic Church in Latin as Joseph Fortuninus Franciscus. The day after that (Tuesday), Verdi's father took his newborn the three miles to Busseto, where the baby was recorded as Joseph Fortunin François; the clerk wrote in French. "So it happened that for the civil and temporal world Verdi was born a Frenchman."
