The Bicentennial World's Fair was an event held on Deneva in 2361, presumably in celebration of the 200th anniversary of the founding of the United Federation of Planets. Denevan Vice-President Garson Tiernan and Jasminder Choudhury both reminisced about the Fair while en route to Ingraham B aboard the USS Enterprise-E in 2381. (TNG novel: Losing the Peace)
