Esperanto Language - Official Use

Official Use

Esperanto has never been a secondary official language of any recognized country. However, there were plans at the beginning of the 20th century to establish Neutral Moresnet as the world's first Esperanto state. Qian Xuantong, a Chinese linguist, promoted the replacement of Chinese with Esperanto. In addition, the self-proclaimed artificial island micronation of Rose Island used Esperanto as its official language in 1968.

The US Army has published military phrase books in Esperanto, to be used in war games by mock enemy forces. In the summer of 1924, the American Radio Relay League adopted Esperanto as its official international auxiliary language, and hoped that the language would be used by radio amateurs in international communications, but its actual use for radio communications was negligible.

Esperanto is the working language of several non-profit international organizations such as the Sennacieca Asocio Tutmonda, a left-wing cultural association, or Education@Internet, which has developed from an Esperanto organization; most others are specifically Esperanto organizations. The largest of these, the World Esperanto Association, has an official consultative relationship with the United Nations and UNESCO, which recognized Esperanto as a medium for international understanding in 1954. Esperanto is also the first language of teaching and administration of one university, the International Academy of Sciences San Marino.
