Esperanto is a constructed international language created by the Polish-Jewish eye doctor Ludwik Lejzer Zamenhof (1859–1917). He published it in Warsaw on 26 July 1887 in a short book known as the Unua Libro ("First Book"), under the pen name Doktoro Esperanto – "Doctor One-who-hopes". The name stuck to the language.

Who speaks Esperanto, and where?
Esperanto has no home country. Its speakers live in more than 120 countries, with the strongest communities in Europe, East Asia and Brazil, and growing groups in Africa. They meet at congresses, host each other through the Pasporta Servo network, and talk online. See where Esperanto is spoken.
What culture does Esperanto have?
More than a century of use has produced original novels and poetry, translations of world classics, music, films, podcasts and magazines. The World Esperanto Congress has met almost every year since 1905, and 15 December, Zamenhof's birthday, is celebrated as Zamenhof Day.
Is Esperanto a success or a failure?
Both views have serious arguments. Esperanto never became the world's second language, as Zamenhof hoped, and critics point to its European vocabulary. Supporters answer that it is by far the most widely used constructed language and has a living community after almost 140 years. We cover the criticism of Esperanto and how it compares with other constructed languages openly.
