Im going to tell you a little bit about Esperanto's history.

After 10 years of creation Esperanto the first book of Esperanto was published in 1887, the number of speakers increased rapidly in East & West Europe, the Russian Empire, the America's, China and Japan. Since then, World Congresses have been held each year, except during the world wars, and usually attract anywhere from 2,000-6,000 people. although it has never been accepted as an official secondary language of any country, some linguists believe it should be, and in 1968 self proclaimed artificial island micro-nation, Rose Island, was the first place it was used as an official first language.
