Due to the First World War, where many Scouts were killed, the first international gathering of Scouts was held in 1920. This, the first Jamboree, was held at London’s Olympia for 8,000 Scouts from 34 Countries.

Jamboree is now an international term used to describe a large gathering of Scouts. Since 1920, World Scout Jamborees have been held almost every four years, except during the Second World War, and hosted all over the world.

1st World Scout Jamboree – 1920
Olympia, London, England, 1920. 8,000 Scouts from 34 countries represented at the roll call. The location was a huge glass-roofed building covering six acres. The concrete floor had to be covered with earth for competitions. Some non-Scout participants: an alligator from Florida, a baby crocodile from Jamaica, a lioness cub from Rhodesia, monkeys from South Africa, a baby elephant, a camel. Baden-Powell acclaimed the Chief Scout of the World. He said, "If it be your will, let us go forth from here fully determined that we will develop, among ourselves and our boys, a commradeship through the worldwide spirit of the Scout brotherhood, so that we may help to develop peace and happiness in the world and goodwill among men."

2nd World Scout Jamboree – 1924
Ermelunden, Copenhagen, Denmark, 1924. Innovations: a week's home hospitality for Scouts after the event; the World Scout Championship. Problems: too many visitors and a deluge! B-P named "Bademester" (Danish for "bathing master"). 4,549 wet Scouts accommodated by the public for a night. Awards for different contests distributed by B-P at Copenhagen Stadium. This Jamboree showed that Scouting was not just a game, but that it made a significant contribution towards education in world citizenship.

3rd World Scout Jamboree – 1929
Arrowe Park, Birkenhead, England, 1929. The coming of age Jamboree celebrating Scouting's 21st anniversary. 69 countries represented by 50,000 Scouts (320,000 visitors!). B-P blew the kudu horn at the opening. The first Scout Promise. B-P became Lord Baden-Powell of Gilwell. Also the "Jamboree of Mud". A golden arrow and a hatchet were buried. Gilded wooden arrows were presented to national contingents. B-P said, "Now I send you forth to your homeland bearing the sign of peace, goodwill and fellowship to all your fellow men. From now on the symbol of peace and goodwill is a golden arrow. Carry that arrow on and on, so that all may know of the brotherhood of men."

4th World Scout Jamboree – 1933
Gödöllö, Hungary, 1933. 25,792 Scouts in camp. The Jamboree daily paper was printed in Hungarian, English, French and German, with contributions in other languages. The unofficial language was "Jamboreese", which consisted mostly of signs emphasized by a happy smile. Each foreign contingent was provided with a "cousin", a local Scout who could help them with the Hungarian language. Air Scouts participated for the first time. First issue of commemorative Scout stamps. The Jamboree badge: the white stag of Hungary. "You may look on that white stag as the pure spirit of Scouting, springing forward and upward, ever leading you onward and upward, to leap over difficulties, to face new adventures."(B-P)

Vogelensang-Bloemendaal, Netherlands, 1937. A total of 28,750 Scouts from 54 countries. Daily displays in the arena. Girl Guides used the arena to welcome Lady Baden-Powell, World Chief Guide. The cleanest Jamboree yet: 120 showers and 650 water taps. 71 bridges over the canals that intersected the site. B-P was eighty years old. On presenting the Jamboree emblem, a Jacob staff, B-P said, "Now the time has come for me to say good-bye. I want you to lead happy lives. You know that many of us will never meet again in this world."

6th World Scout Jamboree – 1947
Jamboree of Peace", Moisson, France, 1947. 24,152 Scouts were present. Ten years since the last Jamboree, and B-P had died in 1941. Loudspeakers were an unpleasant innovation of the time. Indian Scouts celebrated their country's independence. "Challenges" were part of the programme. The final march, in the formation of a Carrick Bend (the symbol of the Jamboree). At the opening ceremony Scouts marched in by countries; at the closing ceremony each sub-camp formed the unit, and bore at its head the many flags and banners of the Scouts of all the countries represented in the sub-camp.

7th World Scout Jamboree – 1951
Salzkammergut, Bad Ischl, Austria, 1951. 12,884 Scouts were present. Simplicity was the keynote of the Jamboree. Seven towers were erected, each recalling a previous Jamboree. As the name of each was announced, a flag was hoisted on one of the towers and the song of that Jamboree sung. It was the first time that German Scouts were able to take part in a World Scout Jamboree as full members of the World Organization. One Scout attended from Japan. He knew no language other than his own and the word "Jamboree", yet he made the journey with no problem. The sight of Scouts waving the welcome flags at the airport told him that he had arrived at the right place.

8th World Scout Jamboree – 1955
The Jamboree of New Horizons, Niagara on the Lake, Canada, 1955. The first World Scout Jamboree and first international Scout gathering to be held outside of Europe. Total of 11,139 participants from 71 countries present. Many firsts: all cooking done over charcoal; television came to a World Scout Jamboree; so did Hurricane Connie! Unusual arrivals were two whaling boats which were sailed up the river from Montreal through the Rideau Canal and across Lake Ontario; three Brazilian Scouts arrived by jeep; New Zealand Scouts who left home four months before the Jamboree started and travelled over 45,000 Km (30,000 miles). The greatest impact: Canadian hospitality.

The year of B-P's centenary. An amateur radio station operated from camp. A Scout from Pakistan hiked all the way. There was a 24-page camp newspaper, "Jubilee Journal". And then, traditonally one might say, there was the night of the great storm - "Jamborain". An obelisk was erected at Sutton Park to commemorate this anniversary of Scouting.

"The Bamboo Jamboree", a nipa palm and Bamboo City. The meeting of Occident and Orient; a revelation to both. The Filipino smile was unforgettable. In view of weather conditions at previous Jamborees, French Scouts, well prepared for all contingencies, marched past giving a splash of colour in yellow raincoats. A World Scout Jamboree is not really the arena shows or campfires. The real Jamboree takes place in the hearts of Scouts from many lands.

Marathon, Greece, 1963. 14,000 participants. Theme: "Higher and Wider". The Greek Crown Prince and Chief Scout opened the Jamboree.

World Scout Jamboree YEAR – 1979
The world is the place and the time is the whole year of 1979. Instead of one Jamboree, the World Organization announced the "World Scout Jamboree Year" in order to multiply by thousands the spirit of a Jamboree by holding several World Scout Jamboree Year camps and countless Join-in-Jamboree activities all over the world. The Join-in-Jamboree symbol represented the waves of friendship that rise from international gatherings of Scouts and flow around the world spreading the spirit of the Scout brotherhood.
