While World Scout Jamboree is the expression used by the
World Organization of the Scout Movement, other organizations held events called "jamborees" for their members. 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. 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 Jamboree site bore the name of the birthplace of the
Olympic Games,
Olympia. 8,000 Scouts from 34 countries attended the event. , published in 1929 for the
3rd World Scout Jamboree 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. To replace the cancelled event of 1979, the
World Scout Committee determined that an alternative celebration, the
World Jamboree Year should take place. Several regional camps took place, such as the 12th Australian/4th Asia-Pacific Jamboree, held in Perth, Western Australia, along with countless Join-in-Jamboree activities — designed to allow Scouts from around the world to participate in an activity that thousands of other Scouts around the world were also participating in at the same time. This
Join-in programme was reproduced again as part of the
Scouting 2007 Centenary celebrations. The greatest attendance of all Jamborees was in 2019, where over 45,000 members experienced a Jamboree in West Virginia, US. This number represented the permanent contingent who remained for the entire event. They were joined by hundreds of thousands of visiting Scouts who participated on a day basis. The first Jamboree was more akin to an exhibition of Scouting, allowing visitors to see how things were done in other parts of the world. The Second Jamboree was conducted on a camp basis and each successive Jamboree has developed on this format where the programme is typically more activity oriented, with plenty of time for Scouts from different nations to interact and learn about each other in less formal ways than an exhibition would allow. The
16th World Scout Jamboree went to the
Southern Hemisphere for the first time, in
Sydney,
NSW,
Australia. The
21st World Scout Jamboree in 2007 was held in
Hylands Park,
Essex, United Kingdom, and celebrated the
Centenary of Scouting. Because of this, the honour of hosting the event was again bestowed upon the United Kingdom, as the birthplace of Scouting. Over 40,000 young people camped in August at
Hylands Park in
Chelmsford,
Essex. Hundreds of thousands of day visitors attended events in the south-east of England as part of the Jamboree. The
22nd World Scout Jamboree was at
Rinkaby, Sweden from 27 July to 8 August 2011; the
23rd World Scout Jamboree was at
Kirara-hama,
Yamaguchi City, Japan from 28 July to 8 August 2015; the
24th World Scout Jamboree was at
The Summit Bechtel Family National Scout Reserve in West Virginia, United States, from 22 July to 2 August 2019. The
25th World Scout Jamboree was at
Saemangeum in
South Korea from 2 to 12 August 2023. It was accompanied by great heat from the beginning, several contingents, including British and American, therefore left the camp. On August 7, the Korean government decided to end the jamboree in Saemangeum early and to evacuate the participants to Seoul, the heat wave was to be replaced by a tropical storm. The jamboree program continued in the capital city of
Seoul, with participants staying at various locations throughout the city, including military bases and universities. The closing ceremony was held at the
Seoul World Cup Stadium, which hosted the
2002 FIFA World Cup. The
26th World Scout Jamboree will be held in 2027 at
Sobieszowo Island near
Gdańsk in
Poland. The
27th World Scout Jamboree will be held in 2031 at
Silkeborg,
Denmark. ==Related world-wide events==
