The country for XXX was what?
Anna Bolena
Felice Romani wrote the Italian libretto after Ippolito Pindemonte's Enrico VIII ossia Anna Bolena and Alessandro Pepoli's Anna Bolena, both recounting the life of Anne Boleyn, the second wife of England's King Henry VIII. It is one of four operas by Donizetti dealing with the Tudor period in English history--in composition order, Il castello di Kenilworth (1829), Anna Bolena (1830), Maria Stuarda (named for Mary, Queen of Scots, it appeared in different forms in 1834 and 1835), and Roberto Devereux (1837, named for a putative lover of Queen Elizabeth I of England).
