On 8 June 2005, Iran together with Japan became the first country to qualify for the 2006 World Cup, making it Iran's 3rd appearance on the world stage of football. The qualification round both in 2001 and 2004–05 resulted in mass celebrations, hysteria and rioting, causing internal chaos and unrest between youth and government officials. The Iran versus Japan leg of the 2006 World Cup qualifiers in Tehran, played on 24 March 2005, was the highest attended qualifying match among all confederations. The match ended in tragedy with 5 fans killed and several others injured as they left the Azadi Stadium at the end of the match.
