Universal Congress of Esperanto

The Universal Congress of Esperanto has the longest tradition among international Esperanto conventions, with an almost unbroken run of nearly a hundred years. The Congresses have been held since 1905 every year, with the only exception being the years of the two World Wars. The Universal Esperanto Association has thus about 100 years of experience in congress organizing.

These congresses take place every year. These congresses gather on average about 2000 participants (since the World War II it has varied from 800 to 6000 depending on the venue). The average number of countries represented is about 60. Some specialized organizations also gather a few hundred participants in their annual meetings. The Universal Congress usually takes place in the last week of July or first week of August, beginning and ending on a Saturday (8 days in total).
