International Youth Congress
The International Youth Congress is the largest annual meeting of young Esperantists in the world. The participants come from all over the world for one week, and they usually number around 300, although there has been a congress with more than 1000 attendees before. The congress takes place in a different country every year and is organized by the World Esperanto Youth Organization, the youth wing of the Universal Esperanto Association. Both the IJK and the World Esperanto Congress take place each summer, usually in consecutive weeks but rarely in the same country.
