Auxiliary languages
Travel topic
Auxiliary languages are artificial or constructed languages created with the intent of facilitating communication between peoples who would otherwise have difficulty communicating. They are separate from lingua francas, which are natural or organic languages that become dominant for one reason or another as means of communication between speakers of other languages.
Esperanto distribution
The speakers of auxiliary languages are not evenly distributed; the chance to find somebody who could communicate with you in that language is much higher in some regions. There are no reliable statistics about Esperanto speakers, but it seems there are more speakers than on average in certain parts of Europe, China, Korea, Japan, Iran, Brazil, Argentina, Mexico, Togo and Madagascar.
History
The first auxiliary language to gain enough ground to have large conferences was Volapük, which held meetings throughout its heyday in the 1880s, with the last one in Paris in 1889, in which participants spoke only in Volapük. Esperanto surpassed Volapük in popularity in the 1890s, and the first Esperanto Congress, the Universal Congress of Esperanto (Universala Kongreso de Esperanto), was held in Boulogne-sur-Mer in 1905. Nearly seven hundred participants, with many from France and Germany, attended. The Universal Esperanto Association has held yearly conferences ever since then, with hiatuses during the world wars. Ido, a relative of Esperanto, has been the subject of conferences since the 1920s.
Events
Of the handful of these languages with substantial communities, a few have meetings and conventions. Esperanto has multiple events most years. Ido has at least one event every year. Interlingua also has at least one event every year.

Home stay
As the speakers usually appreciate meeting fellow speakers, there may be possibilities to have a local host, if you know the language. For Esperanto this is formalized in the Pasporta Servo.
Respect
As the auxiliary languages are a try at replacing lingua francas, such as English, using those in the auxiliary language communities is a touchy issue. Trying to use your own language, the local language, and gestures, where your ability in the auxiliary language in question is not sufficient, may be better received. This of course also depends on the situation and whom you are talking to. It may also be possible to bend words of some other language into a form resembling that of the auxiliary language.
