The five rings represent the flags of the majority of countries that participate in the Olympic events. Blue, yellow, black, green and red, as well as the white in the background, were found in the majority of the nations' flags.
Designed in 1912 by Baron Pierre de Coubertin, it was initially delayed from becoming the official symbol of the Olympics by the beginning of World War I. Finally debuted in the 1920 Summer Olympics, the rings commonly symbolize wholeness and continuity, combined together to indicate peace and fraternity. Up until 1951, the official International Olympic Committee handbook stated that the five rings represented the major regions of the world. Due to little historical evidence of any connection between a particular ring and a specific region by Coubertin, the suggestion was removed.
