Page "Esperanto" Paragraph 17

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.
