What's ULI

The Union for the International Language (ULI) was founded on July 31, 1910 with for mission of developing and of propagating the international auxiliary language Ido.
Ido is a reform of Esperanto made by the Delegation for the adoption of an International Auxiliary Language following the refusal from Esperantists to accept the improvements and simplifications of Esperanto suggested in January 1908 after having met in Paris in October 1907 with the support of more than 1200 members of Academic societies, Faculties, Universities and more than 300 international associations, to select the best project of international auxiliary language.

The main Ido uses the Latin alphabet without accent marks rejecting the accentuated letters ĉ ĝ ĥ ĵ ŝ ŭ specific to Esperanto. Unlike in Esperanto adjectives in Ido do not agree in the plural and in the accusative case, and the use of the ending "n" for the accusative case is not used systematically as it is in Esperanto but only when the subject-verb-object word order is not followed. New affixes like "des-, - iv, - oz, - al" were also introduced. In short, the international auxiliary language Ido, by eliminating the useless complications from Esperanto brings a solution without equal to the global linguistic problem.

Today the ULI whose seat is located in Amsterdam (Holland) is an international association functioning with the assistance of volunteers who work to develop and propagate Ido mainly in the following ways :

- Maintaining the universality of Ido by the Linguistic Committee
- Publishing the quarterly review "Progreso"
- Organizing international Meetings for Ido enthusiasts
- Supporting and assisting national associations of Ido
- Providing information in the media (Internet, press, radio...)
- Searching for patrons
- ...
