On August 14, 1949, 20,000 young people from 82 countries, gathered in the Ujpest Stadium, inaugurating the festival. For two weeks, the participants took part in cultural, sport, and political activities. The festival expressed its solidarity for the "anti-colonialist struggle" of the peoples of Indonesia, Malaysia and French Indochina and also for the "anti-fascist struggle" of the Spanish and Greek peoples. It was the first time that a delegation from what would become East Germany took part.
The motto of the festival was: Youth Unite! Forward for Lasting Peace, Democracy, National Independence and a better future for the people!
