The Federal Republic of Yugoslavia was created in April 1992. It included the Republic of Montenegro and the Republic of Serbia. In May of 1992, the United Nations Security Council said that all nations should not let the FR of Yugoslavia take part in any international sports. The International Olympic Committee said that athletes from Serbia and Montenegro (and also Macedonia) could still take part in the 1992 Summer Olympics in Barcelona. The athletes had to be Independent Olympic Participants (IOP), wear plan white clothing and use the Olympic Anthem and Olympic flag during the events. They could not be a part of the opening and closing ceremonies of the games.
