World Scout Jamboree movement learn about other peoples and nations by direct interaction with them. 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". It was in 1920 that the first World Scout Jamboree was realized, held in the Olympia halls in Kensington, London. Symbolically, the
American Boy Scouts left the ABS in 1910 and formed the New England Boy Scouts. On March 12, 1911, the Rhode Island group voted to break away from the American Boy Scouts and formed the Rhode Island Boy Scouts. The ABS joined the Order of World Scouts in 1911. In August 1911, General Edwin A. McAlpin was elected national president and Chief Scout. In March 1912, an ABS Scout in uniform shot and killed a boy with a rifle after a Scout function. Remington Arms designed the 4S Boy Scout Rifle and advertised it as the "Official Rifle of the American Boy Scouts"
