<P> The Scouting program became an international success following its founding by Robert Baden - Powell in 1907 . With its continuing growth, the founder of the movement saw a need for a gathering of representatives of Scouting from all around the world . The general aim was to foster a worldwide brotherhood, and to help the young Scouts in the movement learn about other peoples and nations by direct interaction with them . </P> <P> The idea of organizing such periodical international gatherings was originally conveyed to Baden - Powell by the General Chief of the Scouts of Greece, Konstantinos ("Kokos") Melas, during the 1918 international Scout meeting, in England. Captain Melas proposed the gatherings should repeat every four years, in the same way Olympic Games were held in Ancient Greece . The suggestion was accepted with enthusiasm by Baden - Powell, who named the gatherings "Jamborees". </P> <P> It was in 1920 that the first World Scout Jamboree was realized, held in the Olympia halls in Kensington, London . Symbolically, the Jamboree site bore the name of the birthplace of the Olympic Games, Olympia . 8,000 Scouts from 34 countries attended the event . </P> <P> Thereafter, a Jamboree has been held every four years . There are two exceptions to this: no Jamboree was held between 1937 and 1947 because of the Second World War, and the 1979 Jamboree, which was to be held in Iran, was cancelled due to the political upheaval in the region at that time . The Jamboree has been held in different countries around the world . The first seven Jamborees were held in Europe . The eighth World Jamboree was held in North America where the tradition of moving the Jamboree among the continents began . As yet, Africa has not hosted a jamboree . </P>
