"La Espero" ("The Hope") is a poem written by L. L. Zamenhof (1859-1917), the initiator of the Esperanto language. The song is often used as the anthem of Esperanto, and is now usually sung to a triumphal march composed by Frenchman Félicien Menu de Ménil (although there is an earlier, less martial tune created in 1891 by Claes Adelsköld, as well as a number of others less well-known). It is sometimes referred to as the hymn of the Esperanto movement.
Some Esperantists object to the use of terms like "hymn" or "anthem" for La Espero, arguing that these terms have religious and nationalist overtones respectively.
Probably the only language in the world with its own flag and anthem, the word "Esperanto" translates as "hope" or "hoping one" and also provides the title of the anthem of the language. The anthem speaks of the goal of the language, to bind the nations together with a common language in peace.
