The Olympic rings were first used by Baron Pierre de Coubertin in 1914. In the Olympic there were only 10 sports but now there is a big difference. And the difference is that there is more than 20 sports in the Olympics, wow!.
The olympic symbols represent the five continents which are Africa Asia, Europe , America, and Australia . The ring colors are blue, yellow, black, green, and red which represents each colour on the flags, like south africa is green, and Australia is blue ,Black is New Zealand, ANd red is Egypt. And last of all Yellow is Europe
because each flag of the countries that were part of the Olympic movement contain at least one of those colors.
The 5 rings interlock with each other to stay put.
