Which composer wrote the opera 'The Barber of Seville'?

Gioachino Rossini wrote the opera The Barber of Seville.

Premiered in Rome in 1816, the opera is an Italian opera buffa based on Pierre Beaumarchais's 1775 comedy Le Barbier de Séville. Its fast-moving plot follows Count Almaviva, Rosina, and Figaro as they try to outwit Rosina's guardian, Dr. Bartolo.

Rossini's version was not the first opera based on Beaumarchais's play. Giovanni Paisiello had created an earlier setting in 1782, and Paisiello's supporters helped cause a hostile reception for Rossini's premiere. The second performance was much more successful, and Rossini's work eventually became the best-known version.

A common mix-up connects the story with Mozart because Mozart wrote The Marriage of Figaro, which is based on the second play in Beaumarchais's trilogy. Rossini's overture is also famous for having been reused from two of his earlier operas rather than being drawn from themes in The Barber of Seville itself.
