The 9th World Festival of Youth and Students was held from 28 July to 5 August 1968 in Sofia, capital city of the then People's Republic of Bulgaria. The festival attracted 20,000 people from 138 countries. Initially, the event was planned to be held in Algeria in the summer of 1965, but due to the military coup in that country the date was postponed, and Bulgaria became the new venue for the festival.
