In lexicography, "Jamboree" is considered an Americanism that traces back to 1860–65 and refers to a joyful, noisy gathering.

[1] The term is believed to originate from the words jabber (rapid, indistinct talk) and shivaree (noisy celebration), with "m" from jam (crowd).

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.

[4][5] Captain Melas proposed the gatherings should repeat every four years, in the same way Olympic Games were held in Ancient Greece.

[citation needed] It was in 1920 that the first World Scout Jamboree was realized, held in the Olympia halls in Kensington, London.

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.

Hundreds of thousands of day visitors attended events in the south-east of England as part of the Jamboree.

It was accompanied by great heat from the beginning, several contingents, including British and American, therefore left the camp.

[8][9][10] 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.

[12] Jamboree on the Air, usually referred to as JOTA, is an international Scouting and Guiding activity held annually on the third full weekend in October.

The event was first held in conjunction with the fiftieth anniversary of Scouting in 1957, and was devised by radio amateur operator Leslie R. Mitchell who used the callsign G3BHK.

[citation needed] Jamboree on the Internet, known by its acronym JOTI, is an international Scouting activity held annually.

JOTI operates alongside JOTA (Jamboree on the Air) and is an official event of the World Organization of the Scout Movement.
