The 19th century was the time when Nationalism was important. Composers were writing music typical of their own countries. Wagner, as we have seen, took German myths for his opera stories. In Spain they had their own kind of opera called “zarzuela”. In Russia Mikhail Glinka (1804-1857) wrote "Ruslan and Lyudmila" which was based on a Russian fairy tale. Other Russian composers include Alexander Borodin who wrote "Prince Igor", and Modest Mussorgsky (1839-1881) who wrote "Boris Godunov". Both these operas are about stories from Russian history. Nikolai Rimsky-Korsakov (1844-1908) wrote a fairy tale opera "Sadko", and Pyotr Tchaikovsky (1840-1893) used some very Russian tunes in "Eugene Onegin" and "The Queen of Spades".
