Alessandro Francesco Tommaso Antonio Manzoni (Italian: [alesˈsandro manˈdzoːni]; 7 March 1785 – 22 May 1873) was an Italian poet and novelist.
He is famous for the novel The Betrothed (orig. Italian: I promessi sposi) (1827), generally ranked among the masterpieces of world literature. The novel is also a symbol of the Italian Risorgimento, both for its patriotic message and because it was a fundamental milestone in the development of the modern, unified Italian language. Manzoni also sat the basis for the modern Italian language and helped creating linguistic unity throughout Italy. He was an influential proponent of Liberal Catholicism in Italy.
