Unua Libro


Dr. Esperanto's International Language (Russian: Международный язык, International Language), commonly referred to as Unua Libro (First Book), is an 1887 book by L. L. Zamenhof, in which he first introduced and described the constructed language Esperanto. First published in Russian on July 26 [O.S. July 14] 1887, the publication of Unua Libro marks the formal beginning of the Esperanto movement.Writing under the pseudonym "Dr. Esperanto", Zamenhof originally referred to the language as the international language; the use of Esperanto did not arise until 1889 when people began to use his pseudonym as the name of the language itself. Zamenhof reproduced a significant portion of the content of Unua Libro in the 1905 Fundamento de Esperanto, which he established as the sole obligatory authority over Esperanto in the Declaration of Boulogne, ratified by the first World Esperanto Congress later that year.
