The Olympic Oath (distinct from the Olympic creed) is a solemn promise made by one athlete, judge or official, and one coach at the Opening Ceremony of each Olympic Games. Each oath taker is from the host nation and takes the oath on behalf of all athletes, officials, or coaches at the Games. The athletes' oath was first introduced for the 1920 Summer Olympic Games, with oaths for the officials and coaches added in 1972 and 2010. The oath is usually said in the language of the nation which is hosting the games; however, in 1994 both the athletes' and officials' oaths were said in English. Until the 1984 games the oath takers swore upon their nation's flag; since then all have taken the oath whilst holding the Olympic Flag. All three of the oaths were combined into one beginning at the 2018
