Giacomo Puccini was an Italian composer known primarily for his operas. Regarded as the greatest and most successful proponent of Italian opera after Verdi, he was descended from a long line of composers, stemming from the late-Baroque era. Though his early work was firmly rooted in traditional late-19th-century Romantic Italian opera, he later developed his work in the realistic verismo style, of which he became one of the leading exponents.

Italian opera is both the art of opera in Italy and opera in the Italian language. Opera was in Italy around the year 1600 and Italian opera has continued to play a dominant role in the history of the form until the present day. Many famous operas in Italian were written by foreign composers, including Handel, Gluck and Mozart. Works by native Italian composers of the 19th and early 20th centuries, such as Rossini, Bellini, Donizetti, Verdi and Puccini, are amongst the most famous operas ever written and today are performed in opera houses across the world.
