By the time the 1920 Games in Antwerp came around, the Olympics were much more established.
The opening ceremony was notable because the Olympic flag, designed in 1913 by founder of the International Olympic Committee Baron Pierre de Coubertin, was flown for the first time.
The Olympic oath, which calls for athletes to respect and abide by Olympic rules, was introduced and Belgian fencer Victor Boin had the honour of reciting it on behalf of all the athletes at the Games.
Doves being released as a symbol of peace also made their debut.
