The World Congress of Esperanto (in Esperanto: Universala Kongreso de Esperanto, acronym UK) has the longest tradition among international Esperanto conventions, with an almost unbroken run of more than a hundred years. The congresses have been held since 1905 every year, except during World Wars I and II. Universal Esperanto Association has been organizing these congresses since the 1920s.
These congresses take place every year and gather on average about 2000 participants (since 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 World 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).
Until 1980, meetings were held in Europe and the United States, with the exception of Japan in 1965. Since then, other countries have been Brazil, Canada, China, Cuba, S. Korea, Australia, Israel and Vietnam.

Famous quotes containing the words world, congress and/or esperanto:
“If the Third World War is fought with nuclear weapons, the fourth will be fought with bows and arrows.”
—Louis, 1st Earl Mountbatten Of Burma Mountbatten (19001979)
“The profession I chose was politics; the profession I entered was the law. I entered the one because I thought it would lead to the other. It was once the same road; and Congress is [s]till full of lawyers.”
—Woodrow Wilson (18561924)
“The new sound-sphere is global. It ripples at great speed across languages, ideologies, frontiers and races.... The economics of this musical esperanto is staggering. Rock and pop breed concentric worlds of fashion, setting and life-style. Popular music has brought with it sociologies of private and public manner, of group solidarity. The politics of Eden come loud.”
—George Steiner (b. 1929)
