Out of Italian Gaetano Donizetti or Czech Bedřich Smetana, which opera composer lived and worked earlier?
Gaetano Donizetti Domenico Gaetano Maria Donizetti (] ; 29 November 1797 – 8 April 1848) was an Italian composer. Along with Gioachino Rossini and Vincenzo Bellini, Donizetti was a leading composer of the "bel canto" opera style during the first half of the nineteenth century. Donizetti's close association with the bel canto style was undoubtedly an influence on other composers such as Giuseppe Verdi (1813–1901).
Khovanshchina Khovanshchina (Russian: Хованщина , "Hovánščina", sometimes rendered The Khovansky Affair; since the ending -ščina is pejorative) is an opera (subtitled a 'national music drama') in five acts by Modest Mussorgsky. The work was written between 1872 and 1880 in St. Petersburg, Russia. The composer wrote the libretto based on historical sources. The opera was unfinished and unperformed when the composer died in 1881.
